Exact effective interactions and 1/4-BPS dyons in heterotic CHL orbifolds
Guillaume Bossard, Charles Cosnier-Horeau, Boris Pioline
Motivated by precision counting of BPS black holes, we analyze six-derivative couplings in the low energy effective action of three-dimensional string vacua with 16 supercharges. B…
Four-derivative couplings and BPS dyons in heterotic CHL orbifolds
Guillaume Bossard, Charles Cosnier-Horeau, Boris Pioline
Three-dimensional string models with half-maximal supersymmetry are believed to be invariant under a large U-duality group which unifies the S and T dualities in four dimensions. W…
Protected couplings and BPS dyons in half-maximal supersymmetric string vacua
Guillaume Bossard, Charles Cosnier-Horeau, Boris Pioline
We analyze four- and six-derivative couplings in the low energy effective action of string vacua with half-maximal supersymmetry. In analogy with an earlier proposal for the…
