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…

On the non-abelian Born-Infeld action
P. Bain
We discuss some aspects of the generalization of the Born-Infeld action to non-abelian gauge groups and show how the discrepancy between Tseytlin's symmetrized trace proposal and s…
