Search for axion-like particles decaying to two photons at Belle II
Belle II Collaboration, M. Abumusabh, I. Adachi +450
Axion-like particles (ALPs) are predicted in many extensions of the Standard Model and provide a well-motivated portal between visible and hidden sectors through their coupling to…
