چکیده
A bstract We study the effect of D-instantons on closed string scattering amplitudes in two-dimensional type 0B theory from worldsheet perspective. find that contribution a pair D-instanton and anti-D-instanton to reflection amplitude, with suitable contour prescription for integration over moduli space, agrees corresponding leading non-perturbative corrections proposed dual matrix quantum mechanics. This analysis is further extended thermal observables defined at finite temperature. The infrared divergence charged processes understood through measure factor D-instantons, can be treated spacetime dimensional regularization.

Absorption of dilaton s-wave in type 0B string theory
We find the absorption probability of dilaton field in type 0B string theory. Since the background solutions are of the form AdS5 × S5 on both regions, we use the semiclassical formalism adopted in type IIB theory to find the absorption cross section. The background tachyon field solution was used as a reference to relate the solutions of the two regions. We also consider the possible correctio...
متن کاملLarge D-instanton effects in string theory
By reduction along the time direction, black holes in 4 dimensions yield instantons in 3 dimensions. Each of these instantons contributes individually at order exp(−|Q|/gs) to certain protected couplings in the three-dimensional effective action, but the number of distinct instantons is expected to be equal (or comparable) to the number of black hole micro-states, i.e. of order exp(Q). The same...
متن کاملD-effects in Toroidally Compactified Type II String Theory
We review exact results obtained for R couplings in maximally supersymmetric type II string theories. These couplings offer a privileged scene to understand the rules of semiclassical calculus in string theory. Upon expansion in weak string coupling, they reveal an infinite sum of non-perturbative e−1/g effects that can be imputed to euclidean D-branes wrapped on cycles of the compactification ...
متن کاملA Matrix Model Dual of Type 0B String Theory in Two Dimensions
We propose that type 0B string theory in two dimensions admits a dual description in terms of a one dimensional bosonic matrix model of a hermitian matrix. The potential in the matrix model is symmetric with respect to the parity-like Z2 transformation of the matrix. The two sectors in the theory, namely the NSNS and RR scalar sectors correspond to two classes of operators in the matrix model, ...
متن کاملNew Instanton Effects in String Theory
An important non-perturbative feature of string theory or M -theory compactifications which preserve only N = 1 supersymmetry in four dimensions is that fundamental string worldsheet or brane instantons can sometimes generate an effective superpotential for the light chiral superfields that describe the classical moduli of the background. Such a superpotential drastically alters the low-energy ...
