A New Term in Type II Effective Action
Ashoke Sen
We show that the one loop effective action of type IIA and IIB string theories in ten dimensions have terms proportional to the dilaton times the ten dimensional Euler density, in…
Revisiting Logarithmic Correction to Five Dimensional BPS Black Hole Entropy
A. H. Anupam, Chandramouli Chowdhury, Ashoke Sen
We compute logarithmic correction to five dimensional BPS black hole entropy using finite temperature black hole geometry and find perfect agreement with the microscopic results an…
Logarithmic Correction to BPS Black Hole Entropy from Supersymmetric Index at Finite Temperature
Anupam A. H., P. V. Athira, Chandramouli Chowdhury +1
It has been argued by Iliesiu, Kologlu and Turiaci in arXiv:2107.09062 that one can compute the supersymmetric index of black holes using black hole geometry carrying finite temper…
Revisiting localization for BPS black hole entropy
Ashoke Sen
Macroscopic computation of the degeneracy / index of a BPS black hole requires carrying out string theory path integral over the near horizon geometry of the black hole. It has bee…
The ZZ annulus one-point function in non-critical string theory: A string field theory analysis
Dan Stefan Eniceicu, Raghu Mahajan, Pronobesh Maity +2
We compute the ZZ annulus one-point function of the cosmological constant operator in non-critical string theory, regulating divergences from the boundaries of moduli space using s…
Infrared finite semi-inclusive cross section in two dimensional type 0B string theory
Ashoke Sen
D-instanton induced S-matrix in type 0B string theory in two dimensions suffers from infrared divergences. This can be traced to the fact that these processes produce low energy ro…
