Calabi-Yau compactification of type II string theories
Sibasish Banerjee
Superstring theories are the most promising theories for unified description of all fundamental interactions including gravity. However, these theories are formulated consistently…
Hypermultiplet metric and D-instantons
Sergei Alexandrov, Sibasish Banerjee
We use the twistorial construction of D-instantons in Calabi-Yau compactifications of type II string theory to compute an explicit expression for the metric on the hypermultiplet m…
Dualities and fivebrane instantons
Sergei Alexandrov, Sibasish Banerjee
We derive the fivebrane instanton corrections to the hypermultiplet moduli space of Calabi-Yau string vacua using S-duality symmetry of the type IIB formulation. The result i…
Fivebrane instantons in Calabi-Yau compactifications
Sergei Alexandrov, Sibasish Banerjee
We provide the last missing piece of the complete non-perturbative description of the low energy effective action emerging from Calabi-Yau compactifications of type II string theor…
