Furthermore these two pictures can be\nincorporated by the CFT duals (general picture) that are generated by\nSL(2,Z) modular group. The general conformal structure can be\nrevealed by looking at charged scalar wave equation in some appropriate values\nof frequency and charge. In this regard, we consider the wave equation of a\ncharged massless scalar field in background of Kerr-Sen black hole and show in\nthe "near region", the wave equation can be reproduced by the Casimir operator\nof a local SL(2,R)_L × SL(2,R)_R hidden conformal\nsymmetry. We can find the exact agreement between macroscopic and microscopic\nphysical quantities like entropy and absorption cross section of scalars for\nKerr-Sen black hole. We then find an extension of vector fields that in turn\nyields an extended local family of SL(2,R)_L ×\nSL(2,R)_R hidden conformal symmetries, parameterized by one\nparameter. For some special values of the parameter, we find a copy of\nSL(2,R) hidden conformal algebra for the charged\nGibbons-Maeda-Garfinkle-Horowitz-Strominger black hole in the strong deflection\nlimit.', 'mimetype': 'text/plain', 'lang': 'en'}, {'sha1': 'dcf43009362508b527be6d8b0406ef995df81a3a', 'content': 'It is recently conjectured that generic non-extremal Kerr black hole could be\nholographically dual to a hidden conformal field theory in two dimensions.\nMoreover, it is known that there are two CFT duals (pictures) to describe the\ncharged rotating black holes which correspond to angular momentum $J$ and\nelectric charge $Q$ of the black hole.
