    Dark SU (2) Stueckelberg portal
    (American Physical Society, 2023-03) Lyubovitskij, Valery E.; Zhevlakov, Alexey S.; Kachanovich, Aliaksei; Kuleshov, Serguei
    We study the non-Abelian SU(2)D extension of the U(1)D Stueckelberg portal, which plays the role of mediator between the Standard Model (SM) and dark sector. This portal is specified by the Stueckelberg mechanism for generation of dark gauge boson masses. The proposed U(1)D - SU(2)D Stueckelberg portal has a connection with SM matter fields, in analogy with the familon model. We derive bounds on the couplings of dark portal bosons and SM particles, which govern diagonal and nondiagonal flavor transitions of quarks and leptons. © 2023 authors.
