DOI: 10.1007/jhep05(2024)094
Abstract: In the minimal U(1) extension of the Standard Model (SM), a new gauge boson referred to as “dark photon” is predicted. The dark-photon mass can be generated from an additional Higgs mechanism associated with a… read more here.

DOI: 10.1007/jhep10(2025)142
Abstract: Dark photons can be resonantly produced in the early universe via their coupling to an oscillating axion field. However, this mechanism typically requires large axion-dark photon couplings or some degree of fine-tuning. In this work,… read more here.

DOI: 10.1088/1475-7516/2023/05/015
Abstract: Wave-like dark matter made of spin-1 particles (dark photons) is expected to form ground state clumps called “vector solitons”, which can have different polarizations. In this work, we consider the interaction of dark photons with… read more here.
