Abstract
The recent observation of GRB 221009A by LHAASO at TeV energies has challenged the accepted emission mechanisms that describe the late emission of GRBs. Given the estimated distance of the event, z=0.151, TeV emission was not expected to be detected due to attenuation with the EBL. For this reason, light dark matter candidates such as ALPs have been proposed to explain the arrival of these TeV photons by assuming either an initial population of TeV photons or ALPs during the evolution of the GRB. In this sense, the detection from LHAASO might be useful to study the parameter space and production of ALPs. In this study we present the constrains on the ALPs parameter space by exploring different temporal profiles for the TeV emission from possible ALP production in the GRB 221009A.
