NPA Seminar, Julieta Gruszko, UNC, “Discovering Neutrinoless Double-Beta Decay with LEGEND”

Why is the universe dominated by matter, and not antimatter? Neutrinos, with their changing flavors and tiny masses, could provide an answer. If the neutrino is a Majorana particle, meaning that it is its own antiparticle, it would reveal the origin of the neutrino’s mass, demonstrate that lepton number is not a conserved symmetry of nature, and provide a path to leptogenesis in the early universe. To discover whether this is the case, we must search for neutrinoless double-beta decay, a theorized process that would occur in some nuclei.

NPA Seminar, Michael Ramsey-Musolf, University of Massachusetts, “Was There an Electroweak Phase Transition?”

Abstract: The possible existence of beyond Standard Model physics at the TeV scale or below has important implications for the thermal history of electroweak symmetry-breaking. A first order phase transition – not possible in the minimal Standard Model with a 125 GeV Higgs boson – would provide the preconditions for electroweak baryogenesis and the generation of primordial gravitational radiation. I discuss recent developments in assessing this possibility that rely on the combination of EFT methods and non-perturbative (lattice) computations.

Connecting Past to Present: Building a Cultural Heritage Center in Lagos, Nigeria

Join us for the launch of the Yale IPCH Public Talks: a series dedicated to exploring global perspectives and critical developments that impact cultural heritage preservation. In this inaugural event, this distinguished expert panel will contextualize the highly anticipated John Randle Centre for Yoruba History and Culture within the economic, social, and cultural landscape of Lagos, the most populous city on the African continent.
