Abstract

Recently, the asymptotic symmetry has been investigated in order to understand infrared physics better in QED. In particular, the memory effects and soft theorems turned out to be understood as consequences of the asymptotic symmetry. In this talk, I will start with the review of the triangle equivalences between the asymptotic symmetry, memory effects and soft theorems. Then, I will discuss our results about the charge conservation law associated with the asymptotic symmetry, physicalness of the symmetry in BRST formalism, and new conserved charge associated with the sub-leading soft theorem in massive scalar QED.
