Normalization of D instanton amplitudes in two dimensional type 0B string theory

Abstract: We compute the normalization of the D-instanton amplitudes in type 0B string theory in two dimensions and find perfect agreement with the dual matrix model result.

“…On the other hand, a D-instanton -anti-D-instanton induced process involves either the transmission of a fermion and a hole across the barrier, or a non-perturbative contribution to the reflection amplitude of a fermion or a hole. In either case, the final state represents fermion hole pair excitations on the same side of the barrier, and therefore can be interpreted as a regular closed string state, On the string theory side this is reflected in the fact that the amplitudes induced by a D-instanton anti-D-instanton pair are infrared JHEP04(2023)101 finite, Explicit computation of these amplitudes yield results in perfect agreement with the predictions of the matrix model [14,15].…”
