SUMMARY:[High Energy Physics Seminars] Raffaele-Tito D'Agnolo: Crunching Dilaton\, Hidden Naturalness
DESCRIPTION:https://zoom.us/j/3601731049 \nWe introduce a new approach to the Higgs naturalness problem\, where the value of the Higgs mass is tied to cosmic stability and the possibility of a large observable Universe. The Higgs mixes with the dilaton of a CFT sector whose true ground state has a large negative vacuum energy. If the Higgs VEV is non-zero and below O(TeV)\, the CFT also admits a second metastable vacuum\, where the expansion history of the Universe is conventional. As a result\, only Hubble patches with unnaturally small values of the Higgs mass support inflation and post-inflationary expansion\, while all other patches rapidly crunch. The elementary Higgs VEV driving the dilaton potential is the essence of our new solution to the hierarchy problem. The main experimental prediction is a light dilaton field in the 0.1-10 GeV range that mixes with the Higgs. Part of the viable parameter space has already been probed by measurements of rare B-meson decays\, and the rest will be fully explored by future collide rs and experiments searching for light\, weakly-coupled particles. \n

SUMMARY:[High Energy Physics Seminars] Admir Greljo: The Neutrino Magnetic Moment Portal: Cosmology\, Astrophysics\, and Direct Detection
DESCRIPTION:Via zoom https://zoom.us/j/3601731049 \nWe revisit the physics of neutrino magnetic moments\, focusing in particular on the case where the right-handed\, or sterile\, neutrinos are heavier (up to several MeV) than the left-handed Standard Model neutrinos. The discussion is centered around the idea of detecting an upscattering event mediated by a transition magnetic moment in a neutrino or dark matter experiment. Considering neutrinos from all known sources\, as well as including all available data from XENON1T and Borexino\, we derive the strongest up-to-date exclusion limits on the active-to-sterile neutrino transition magnetic moment. We then study complementary constraints from astrophysics and cosmology\, performing\, in particular\, a thorough analysis of BBN. We find that these data sets scrutinize most of the relevant parameter space. Explaining the XENON1T excess with transition magnetic moments is marginally possible if conservative assumptions are adopted regarding the supernova 1987A and CMB constraints. Finally\, we discuss model-building challenges that arise in scenarios that feature large magnetic moments while keeping neutrino masses well below 1 eV. We present a successful ultraviolet-complete model of this type based on TeV-scale leptoquarks\, establishing links with muon magnetic moment\, B physics anomalies\, and collider searches at the LHC. \nhttps://zoom.us/j/3601731049
