About the INPA Seminars

All seminars are on Fridays (unless otherwise noted) and start at 12:00 (noon) with a brief presentation of the weekly scientific news. Typically the talks end by 13:00. The seminars take place in Bldg. 50A, room 5132.

The committee members are:

The following Seminar schedule for the Institute for Nuclear and Particle Astrophysics is tentative. The seminar becomes final usually a few days before the Friday of the talk.

VIRTUAL INPA SEMINAR | Julie Pagès (University of Zurich)

January 28 @ 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.

INPA guests from campus can now come up to the lab early on Fridays. The INPA Common Room (50-5026) is reserved for our guests from 10:00 am to 12:00 noon, and from 1 pm to 5 pm. Note that the seminars are now held in 50A-5132 to accommodate a larger number of attendees.

Also, on Fridays from 1:00 pm to 2:00 pm you are welcome to join the INPA Speaker for a brown-bag lunch in the small Pers Hall conference room, 54-130B.

INPA Tea Series

The Physics and Nuclear Science Divisions have together been leaders in revolutionary changes in our understanding of neutrinos and cosmology. Everyone is welcome to attend the open forum. Tea and light refreshments will be served.
