Description

Leona Woods Lecture. (Will be held remotely.)

Abstract:

The most popular directions of model building beyond the Standard Model focus on new phenomena at the high-energy scales of the early Universe. As an alternative direction, we have developed late-Universe solutions to the neutrino mass and strong CP problems at a new low-energy gravitational scale, which is numerically coincident with the scale of dark energy. In my talk, I will focus on the neutrino mass model and discuss some of its phenomenological implications, in particular the weakening of the cosmological neutrino mass bounds and the distinction between Majorana and Dirac neutrinos through astrophysical neutrino decays. This talk is based on 1602.03191, 1608.08969, 1811.01991, 1905.01264, and 2102.13618.
