we study the effect of d-instantons on closed string scattering amplitudes in the two-dimensional type 0b string theory from the worldsheet perspective. we find that the contribution from a pair of d-instanton and anti-d-instanton to the closed string reflection amplitude, with a suitable contour prescription for the i... | the s-matrix of 2d type 0b string theory. part ii. d-instanton effects |
in this paper we have studied the propagation of a massless scalar field minimally coupled to a black hole with the source of cloud of strings in 2 + 1 f(r) gravity theory. in particular we have found analytical results for the decay rate, reflection coefficient, greybody factors, as well as the black hole temperature.... | quasinormal modes and greybody factors of f(r) gravity minimally coupled to a cloud of strings in 2 + 1 dimensions |
light probes interacting with heavy bound states such as black holes give rise to observables containing valuable dynamical information. recently, a family of black hole microstates was shown to admit an exact string worldsheet description. we construct the physical vertex operators of these models, and compute an exte... | worldsheet correlators in black hole microstates |
