SUMMARY:Seminar by Claudia Frugiuele (INFN\, Milan): "Is the large uncertainty of deltaCP fundamentally encoded in the neutrino quantum state?"
DESCRIPTION:Title: “Is the large uncertainty of deltaCP fundamentally encoded in the neutrino quantum state?” \nSpeaker: Seminar Claudia Frugiuele (INFN\, Milan) \nVenue & Time: Red Room / 15:00 \nAbstract: Quantum estimation theory provides a framework to quantify the ultimate precision limits for parameter estimation in physical systems. I will introduce its basic concepts and apply them to neutrino oscillations\, focusing on the estimation of the PMNS parameters. \nA central puzzle is why the CP\, violating phase δCP remains significantly less constrained than the other mixing parameters. Using quantum estimation tools\, I will  show that this limitation is not due to a lack of information encoded in the neutrino quantum state. Instead\, it arises from the suboptimal nature of standard flavor measurements\, particularly near the first oscillation peak. \nI will then compare the achievable precision with that of other mixing parameters\, for which current measurements are already close to optimal. \nI will conclude with the case of astrophysical neutrinos\, where the same tools quantify how much information on the PMNS parameters and on the source composition is lost to phase averaging and to flavor-only measurements.

SUMMARY:Seminar by Carlos Garcia Garcia (CIEMAT): “The status of single scalar field dark energy”
DESCRIPTION:Title: The status of single scalar field dark energy \nSpeaker: Carlos Garcia Garcia (CIEMAT) \nVenue & Time: Red Room / 15:00 \nAbstract: We are entering an exciting era in cosmology\, with tantalizing hints of dynamical dark energy. While current data are not yet sufficient to determine its nature\, they may already provide clues about its microphysical origin. Assuming the latest observations (DESI BAO + SNe Ia + CMB) are correct\, I will show that the evidence for dynamical dark energy remains mild and depends on prior choices. Furthermore\, assuming dark energy arises from a single scalar field\, I will show that current data mildly favor models with a negative squared mass and either a non-minimal coupling to gravity or a non-standard kinetic term. These scenarios lead to distinct signatures in the ISW effect\, the growth of cosmic structure\, and Solar System tests of gravity. I will discuss why current probes are not yet sufficient to distinguish between them and the prospects for uncovering the microphysical nature of dark energy with upcoming observations.

SUMMARY:Seminar by Cypris Plantier (LPSC\, Grenoble): “Various aspects of higher-form fields: from gauge-group topology to dark matter”
DESCRIPTION:Speaker: Cypris Plantier (LPSC\, Grenoble) \nVenue & Time: Red Room / 15:00 \nTitle: Various aspects of higher-form fields: from gauge-group topology to dark matter \nAbstract: Quantum field theory allows for the existence of antisymmetric tensorial gauge fields possessing several Lorentz indices. These so-called higher-form fields constitute intriguing\, ambiguous objects sitting at the interface between local dynamics and global topology: they naturally couple to extended operators\, encode topological structures\, and play a central role in characterizing the vacuum structure of non-abelian gauge theories. At the same time\, those are shown to propagate physical scalar and vectorial degrees of freedom\, making higher-form fields natural and promising dark matter candidates.\nThis seminar will present a historical and conceptual overview of higher-form fields\, focusing on their application to dark matter physics. Particular emphasis will be placed on the recent developments regarding the interplay between duality and dark matter portals within effective field theory frameworks.
