SUMMARY:PhD dissertation: 'Shedding light on extended scalar sectors'
DESCRIPTION:By Víctor Enguita \nVenue & Time: Red Room / 12:00 \nAbstract: \nThe Standard Model has a number of traits which are surprising from the theoretical perspective and may hint the presence of some underlying hidden structure beyond the SM. In this thesis\, we explored some of the open problems which materialize from those traits and could be solved by the presence of an extended scalar sector. First\, we considered axion-like particles (ALPs) using an Effective Field Theory (EFT) approach and imposed improved limits on their CP-odd couplings to fermions. The remainder of the thesis was devoted to the Electroweak hierarchy problem (EWHP). We presented two original works which follow two different guiding principles\, one traditional and the other rather innovative: symmetry and near-critical dynamics. The first among these works presents non-abelian discrete symmetries as able to suppress large radiative corrections and stabilize the masses of scalar particles. In the second contribution\, we argue that the small observed mass of the Higgs could be a trademark of the near-criticality of the Higgs sector\, backed by the observation that every parameter in the Higgs potential seems in fact to also be near-critical.  We explore the consequences of this fact using the so-called “Higgs metastability bound” in the case of a concrete model—the low-scale Majoron model—and demonstrate that this justification of the mass of the Higgs implies new experimental signals in future experiments and in particular\, in the future colliders. We argue that this conclusion is actually more general and should apply to wider contexts than the concrete model analysed.\nSupervisors: Belén Gavela & José Miguel No

SUMMARY:2nd EDI Training: 'Beyond law: Invisible Barriers to Women’s Access to Public Life'
DESCRIPTION:Speaker: Soledad Escobar Villegas \nPhD in Political Science and García Pelayo Research Fellow at the Centre for Political and Constitutional Studies\, Ministry of the Presidency (Spain). \nAbstract: Over the last decades\, Western societies has introduced significant legislative changes aimed at promoting gender equality and increasing the representation of women in decision-making positions. However\, legal progress does not always translate into equal participation in practice. \nThis seminar will examine the gender representation gap in politics and society by distinguishing between formal legislative advances and the structural constraints and internal dynamics within political and social environments that continue to limit women’s access to the public sphere. The session will analyze patterns of underrepresentation and explore factors such as unequal career progression\, workplace cultures\, and informal power structures. It adopts an intersectional approach\, considering not only gender but also women’s ethnic and cultural backgrounds. The aim is to encourage students to critically assess how social and institutional systems shape women’s representation. \nThis seminar aligns with the objectives of the scientific outreach and culture component outlined in the Severo Ochoa project (CEX2020-001007-S\, funded by MCIN/AEI/10.13039/501100011033). In addition to scientific excellence\, this project highlights the center’s commitment to a strong program of training and outreach activities with high social impact. In this context\, organizing training activities on equality\, diversity\, and inclusion helps to reinforce the role of the IFT as an institution committed to social responsibility and the continuous improvement of the scientific environment. This seminar provides tools to analyze the structural barriers present in the scientific field\, particularly in STEM disciplines such as theoretical physics\, aligning with the objectives of attracting and retaining diverse talent that foster an inclusive scientific environment.

SUMMARY:PhD dissertation: 'On String Phenomenology From a Swampland Perspective'
DESCRIPTION:Author: Gonzalo F. Casas\n\n\nTitle: On String Phenomenology From a Swampland Perspective.\n\n\nVenue & Time: Blue Room / 11:00\n\n\nAbstract:  This thesis investigates the deep interplay between particle physics\, cosmology\, and quantum gravity within the framework of string phenomenology. Focusing on Type IIA Calabi–Yau orientifolds with intersecting D6-branes\, we show that the suppression of neutrino masses at infinite-distance limits necessarily entails the emergence of light towers of states. This result establishes a direct link between particle-scale physics and the geometry of extra dimensions\, while also suggesting potentially testable phenomenological signatures. The thesis further connects inflationary dynamics to the quantum-gravity cutoff and examines how supersymmetry breaking in no-scale vacua can give rise to Minkowski backgrounds\, offering a novel perspective on moduli stabilization.\n \nSupervisor: Fernando Marchesano

SUMMARY:PhD Defense by Marienza Caldarola: 'Unveiling the Universe with Gravitational Waves: a Machine Learning approach'
DESCRIPTION:Title: Unveiling the Universe with Gravitational Waves: a Machine Learning approach\n\nVenue & Time: Blue Room / 10:30\n\nAbstract: This thesis is devoted to the study of gravitational waves\, combining theoretical investigations with novel applications of machine learning. The first part of the work addresses the dynamics of hyperbolic encounters\, a class of transient gravitational wave signals. By incorporating orbit precession and post-Newtonian corrections\, this study provides theoretical insights into the emission properties.\nThe second part shifts toward data-driven approaches\, exploring the use of advanced machine learning methods in gravitational waves field. Two main applications are considered: constraining the energy density of the stochastic gravitational wave background through astrometric measurements and inferring the properties of lensed gravitational wave signals. In both cases\, the machine learning frameworks developed here show significant gains in computational efficiency\, with particular promise for real-time signal analysis and alerts\, demonstrating the transformative role of machine learning in enhancing current and future gravitational wave data analysis strategies.\n\nSupervisors: Savvas Nesseris and Sachiko Kuroyanagi

SUMMARY:PhD Defense by Lorenzo Paoloni: "On the Moduli Space Curvature and Gravity Decoupling"
DESCRIPTION:Title: On the Moduli Space Curvature and Gravity Decoupling\n\nVenue & Time: Blue Room / 10:00-12:30\n\nAbstract: This thesis investigates the asymptotic regimes of four-dimensional N = 2 supergravity moduli spaces\, seeking a robust geometric definition of gravity decoupling. It does so in the context of the Swampland Program\, whose primary objective is to delineate the precise boundaries between consistent low-energy effective field theories and those incompatible with quantum gravity. Ultimately\, this thesis establishes a precise\, quantifiable dictionary between macroscopic moduli space geometry and microscopic quantum field theory constraints\, demonstrating that scalar curvature divergences at infinite distance are not geometric artifacts\, but rather the definitive sentinels of quantum field theories successfully isolating themselves from gravity.\n\n\n\n\nSupervisor: Fernando Marchesano

SUMMARY:PhD Defense by Jesús Gambín Egea: “Quantum Properties of Inflationary Perturbations”
DESCRIPTION:Title: Quantum Properties of Inflationary Perturbations\n\nVenue & Time: Orange Room / 15:00-16:30\n\nAbstract: This thesis studies quantum aspects of inflationary perturbations beyond tree level\, with particular emphasis on loop corrections and renormalization. We develop a practical implementation of dimensional regularization for inflationary in-in calculations\, based on separating infrared and ultraviolet contributions and exploiting the universal high-momentum behavior of the mode functions. This allows the ultraviolet renormalization of inflationary observables to be carried out in a largely model-independent way. We apply these methods to the renormalization of scalar and tensor power spectra and of the scalar bispectrum\, and investigate which loop corrections represent intrinsically loop-generated physical effects\, as opposed to contributions that are degenerate with local counterterms. We also study the limits of classical stochastic descriptions of inflationary fluctuations and the non-Gaussian statistics relevant for primordial black-hole formation.\n\n\n\n\nSupervisor: Guillermo Ballesteros

SUMMARY:PhD Defense by David Alonso-González: Into The Dark: Novel and Complementary Searches in Hidden Sectors
DESCRIPTION:Title: Into The Dark: Novel and Complementary Searches in Hidden Sectors\n\nVenue & Time: Blue Room / 11:00-13:30\n\nAbstract: This thesis explores weakly coupled extensions of the Standard Model\, focusing on hidden sectors that may evade conventional experimental searches while addressing some of the main open questions in particle physics\, such as the nature of dark matter and the origin of neutrino masses. The work is organized around three complementary case studies involving a thermal dark matter candidate connected to the Standard Model through a vector portal\, axionlike particles produced in core-collapse supernovae and their possible detection at terrestrial neutrino experiments\, and the interplay between dark matter direct detection experiments and spallation source facilities to constrain the properties of sterile neutrinos. These three works emphasize the importance of combining different experimental strategies to constrain or reconstruct new weakly coupled physics scenarios.

SUMMARY:PhD Defense by Indira Ocampo Justiniano: A machine learning approach for unraveling the nature of dark matter and dark energy
DESCRIPTION:Title: A machine learning approach for unraveling the nature of dark matter and dark energy \nVenue & Time: Orange Room / 11:00-13:00 \n\nAbstract: Cosmology nowadays is benefiting from an exponential increase of data\, transforming into a precision science. This will help us understand better two of the most important open issues in theoretical physics\, namely understanding the nature of dark matter and dark energy. However\, the vast quantity and quality of the data collected from present and upcoming cosmological surveys has become so demanding\, that sophisticated computational tools are required. As a result\, machine learning methods are being implemented for data analysis and model constraints with the hope of alleviating tensions in the parameters inferred from different cosmological probes. A significant challenge remains in the complexity of these models: as architectures become more accurate\, this usually comes with the trade-off of their interpretability. This can lead to a lack of transparency and trustworthiness in a field that demands validation based on physical laws. The research presented in this thesis focuses on different architectures based on neural networks to search for signatures of physics beyond ΛCDM\, with a particular emphasis on interpretability tools that allow extracting the most informative data for the model’s predictions. \nSupervisor: Savvas Nesseris \n\nA small reception will take place afterwards on the terrace of IMDEA around 13:00. \n  \n
