Description
In Beyond Standard Model (BSM) theories, Axion-Like Particles (ALPs) are hypothesized to be Pseudo-Nambu-Goldstone bosons that have spontaneously broken the global Peccei-Quinn (PQ) symmetries at very high energies. Due to the approximated symmetry shifts, the ALPs are naturally lighter compared to the electroweak or QCD particles. Future high-precision experiments may be able to find ALPs that have masses that are well below the GeV scale, but future high-energy lepton and hadron colliders may also be able to search for the heavier ALPs. Therefore, this establishes them as the prime targets for future experiments that are aimed at the discovery of new physics that goes beyond the known and widely accepted Standard Model (SM) of particle interactions. In this work, we investigate the possibility of detecting ALP via the charged and neutral current processes at future ep colliders. We probe couplings of ALP with photon and weak bosons (W and Z) of SM using angular observables and give constraints on these couplings which may direct the community to compare possibilities at various colliders.
