Hidden conformal symmetry for dyonic Kerr-Sen black hole and its gauged family

In this talk, Dr. Muhammad F. A. R. Sakti (High Energy Physics Theory Group, Department of Physics, Faculty of Science, Chulalongkorn University, Bangkok, Thailand) explores the conformal invariance of the dyonic Kerr-Sen black hole and its gauged family. He considers a neutral massless scalar probe on the black holes’ background within the low-frequency limit and exhibit that the solution space possesses SL(2,R)×SL(2, R) isometry. He then successfully derives the Bekenstein-Hawking entropy using Cardy entropy formula from 2D CFT.
