The Phenomenology of Quadratically Coupled Ultra Light Dark Matter
Abhishek Banerjee, Gilad Perez, Marianna Safronova +2
We discuss models of ultralight scalar Dark Matter (DM) with linear and quadratic couplings to the Standard Model (SM). In addition to studying the phenomenology of linear and quad…
High quality Nelson-Barr solution to the strong CP problem with
Gilad Perez, Aviv Shalit
We discuss composite UV completions of the Nelson-Barr(NB) solution to the strong CP problem. In our construction, the CP symmetry is broken spontaneously by the dynamics of a hidd…
The Hierarchion, a Relaxion Addressing the Standard Model's Hierarchies
Oz Davidi, Rick S. Gupta, Gilad Perez +2
We present a mechanism that addresses the electroweak, the strong CP, and the flavor hierarchies of the Standard Model (including neutrino masses) in a unified way. The naturalness…
The Nelson-Barr Relaxion
Oz Davidi, Rick S. Gupta, Gilad Perez +2
Cosmological relaxation models in which the relaxion is identified with the QCD axion, generically fail to account for the smallness of the strong CP phase. We present a simple alt…
