Dark SU(2) Stueckelberg portal

High Energy Physics - Phenomenology 2023-03-29 v3

Abstract

We study the non-abelian SU(2)DSU(2)_D extension of the U(1)DU(1)_D Stueckelberg portal, which plays a role of the mediator between the Standard Model (SM) and Dark Sector (DS). This portal is specified by the Stueckelberg mechanism for generation of dark gauge boson masses. Proposed U(1)D×SU(2)DU(1)_D\times SU(2)_D Stueckelberg portal has a connection with SM matter fields in analogy with Familon Model. We derive bounds on the couplings of dark portal bosons and SM particles, which govern diagonal and non-diagonal flavor transitions of quarks and leptons.
