Description
Core-collapse supernovae are powerful probes of physics beyond the Standard Model (BSM). In this talk, I will show how the circumstellar medium (CSM) affects supernova-based BSM searches using dark photons as an example. The decay product of dark photon can heat up CSM and lead to extra blackbody emission. Using the early-time observations of SN 2023ixf, we derive the strongest constraint on the DP parameter space.
