Aspects of D-Instantons
Michael Gutperle
An overview over effects of D-instantons in ten dimensional IIB superstring theory is given, including the supergravity instanton solution, instanton induced effective interaction…
D-particle bound states and the D-instanton measure
M. B. Green, M. Gutperle
A connection is made between the Witten index of relevance to threshold bound states of D-particles in the type IIA superstring theory and the measure that enters D-instanton sums…
Sixteen-fermion and related terms in M-theory on T**2
Michael B. Green, Michael Gutperle, Hwang-hyun Kwon
Certain one-loop processes in eleven-dimensional supergravity compactified on T**2 determine exact, non-perturbative, terms in the effective action of type II string theories compa…
One loop in eleven dimensions
M. B. Green, M. Gutperle, P. Vanhove
Four-graviton scattering in eleven-dimensional supergravity is considered at one loop compactified on one, two and three-dimensional tori. The dependence on the toroidal geometry d…
Contact terms, symmetries and D-instantons
Michael Gutperle
The scattering of NS-NS antisymmetric tensor states in the presence of D-instantons in type IIB superstring theory is studied. It is shown that in order to preserve gauge invarianc…
Effects of D-instantons
Michael B. Green, Michael Gutperle
Scattering of fundamental states of type IIB supergravity and superstring theory is discussed at low orders in perturbation theory in the background of a D-instanton. The integrati…
