Large neutrino mass in cosmology and keV sterile neutrino dark matter from a dark sector

IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain

Seminars_es

Speaker: Thomas Schwetz from Karlsruhe Institute of Technology (KIT) Venue&Time: Red Room / 3:00 PM Abstract: Recent results from cosmology place sever upper bounds on the sum of neutrino masses, starting to be in conflict with lower bounds from neutrino oscillations. If this neutrino tension persists, it may indicate new physics in cosmology and/or neutrino […]

Searching for New Physics through the Neutrino (bag)pipe

IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain

PhD Dissertation_es

Daniel Naredo Tuero PhD dissertation Searching for New Physics through the Neutrino (bag)pipe Venue&Time: Red Room / 11:00 Abstract: Among the many open problems that plague the Standard Model (SM) of particle physics, the massive nature of neutrinos stands out as it is one of the few indications of New Physics that we have observed […]

Holo Club: Explicit Connections Between Krylov and Nielsen Complexity

Gray Room 3 Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain

Journal clubs_en

Speaker: Le-Chen Qu (IFT) Venue&Time: Grey Room 3 / 11:30 Abstract: We establish a precise correspondence between Krylov complexity and Nielsen complexity in quantum many-body systems. By identifying the Krylov basis with the generators of elementary gates in Nielsen's geometric framework, the Krylov complexity of precursor operators acquires a geometric interpretation as the length of […]

SPS Journal Club: ‘Probing the Rigidity of String Theory’

IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain

Journal clubs_en

Speaker: Georgina Staudt (Max Planck Institute Munich) Venue&Time: Red Room / 12:00 Abstract: We investigate the deformability of the Veneziano amplitude. If string theory is the unique theory of quantum gravity, the tree level amplitudes of weak coupling limits should be non-deformable. We make progress in this direction for tachyon-free superstring theories by deriving a […]

DIFT Colloquium: ‘Gamma Ray Bursts, Cosmic Rays and the Sociology of Science’

AULA POLIVALENTE UAM Plaza Mayor Campus de Cantoblanco UAM. C. Einstein, 7, Fuencarral-El Pardo, 28049 Madrid, Madrid, Madrid, Spain

Seminars_es

Speaker: Álvaro de Rújula from IFT & CERN Venue & Time: Aula Polivalente UAM Abstract: Gamma-Ray Bursts (GRBs) and Cosmic Rays (CRs) are not difficult to comprehend. Quasars and micro-quasars are seen to emit highly relativistic “Cannonballs” (CBs), though the underlying mechanism remains unfathomable. The observation that core-collapse supernovae also emit CBs —plus some trivial […]

Old Journal Club: ‘Renormalization and Effective Lagrangians’

Blue Room Instituto de Física Teórica (IFT) - C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain

Journal clubs_en

Pau Garcia Romeu (IFT) will present Renormalization and Effective Lagrangians by Joseph Polchinski. Venue&Time: Blue Room / 17:00 Abstract: There is a strong intuitive understanding of renormalization, due to Wilson, in terms of the scaling of effective lagrangians. We show that this can be made the basis for a proof of perturbative renormalization. We first […]

Open String Axiverse

IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain

Journal clubs_en

Speaker: Giovanni Villadoro from ICTP Venue & Time: Red Room / 15:00 Abstract: Localized charged fields are a general feature of many realistic string compactifications. I will review how in four dimensions they can lead to a multitude of perturbatively-exact global symmetries that, when spontaneously broken, generate a new axiverse compatible with post-inflationary evolutions.
