D-branes in a plane wave from covariant open strings
Pascal Bain, Kasper Peeters, Marija Zamaklar
We derive boundary conditions for the covariant open string corresponding to D-branes in an Hpp-wave, by requiring kappa symmetry of its bulk action. Both half-supersymmetric and q…

Instanton corrections to the effective action of the CHL string and its type I dual
P. Bain
In this letter, we investigate corrections to quartic gauge couplings in compactifications of string theories on a 2-torus without vector structure. First, we calculate the thresho…
