Abstract

Aspects of superstring theory on black-strings backgrounds, corresponding to deformed BTZ black holes, formed near k NS5 branes by p fundamental strings, and single-trace TT¯+JT¯+TJ¯ holography, are presented. It is shown that for a particular asymptotic value of the B-field, the excitation energy of a long string plus its contribution to the energy of the black hole is that in TT¯+JT¯+TJ¯ deformed CFT₂ with c = 6k. The excitation energy of a winding w > 1 long string plus its contribution to the background, a w/p fraction of the black-hole energy, evolves according to that in a Z_w twisted sector of a p-fold symmetric product of the latter.
