Institute for Nuclear and Particle Astrophysics (INPA) at LBNL

The INPA Seminar weekly talks are on Fridays, starting at 12:00 pm, unless informed otherwise. The seminar talk starts with a brief presentation of the weekly scientific news. Typically, the talks conclude by 1:00 pm. The seminars are held in the Sessler Conference Room,  located in Bldg. 50A- 5132.

The committee members are:

The seminar schedule for the Institute for Nuclear and Particle Astrophysics (INPA) is tentative and becomes final a few days before the Friday talk.

Please send all suggestions for future INPA talks and speakers to the INPA Committee.

VIRTUAL INPA SEMINAR | Julie Pagès (University of Zurich)

January 28, 2022 @ 12:00 pm - 1:00 pm

Location: via Zoom

Speaker: Julie Pagès (University of Zurich)

Title: Different Flavors For Different Particles: Mass Hierarchies, B Anomalies, and Neutrinos 

Abstract:

Despite many advances in neutrino physics, their masses are still not known and their mass generation remains mysterious. On the other hand, quarks and charged leptons exhibit a very hierarchical mass spectrum which can be well described by an approximate U(2)5 flavor symmetry. Coincidently, the B anomalies, hinting at Lepton Flavor Universality Violation, seem to require the same flavor structure of new interactions. The flavor non-universal Pati-Salam model establishes the connection explicitly by unifying quarks and leptons, providing a combined explanation of the charged and neutral current B anomalies and, at the same time, of the mass hierarchies in the SM… except for the neutrinos, which once again seem to defy the trend with their anarchic mass spectrum. In this talk, I will discuss a resolution to this apparent problem through the Inverse Seesaw mechanism and briefly mention how a natural interpretation can be found in the context of extra-dimensions. Finally, I will present the main signatures to expect from this neutrino extension.
