Dyon dynamics near marginal stability and non-BPS states
Adam Ritz, Arkady Vainshtein
We derive the general form of the moduli-space effective action for the long-range interaction of two BPS dyons in N=2 gauge theories. This action determines the bound state struct…
Black holes and universality classes of critical points
Pavel Kovtun, Adam Ritz
We argue that there exists an infinite class of conformal field theories in diverse dimensions, having a universal ratio of the central charge c to the normalized entropy density c…
Superconformal R-charges and dyon multiplicities in N=2 gauge theories
Adam Ritz
N=(2,2) theories in 1+1D exhibit a direct correspondence between the R-charges of chiral operators at a conformal point and the multiplicities of BPS kinks in a massive deformation…
Central charges, S-duality and massive vacua of N=1* super Yang-Mills
Adam Ritz
We provide a simple derivation of the extremal values of the superpotential in massive vacua of N=1* SYM, making use of the required modular weight for the central charge of BPS wa…
Enhanced Worldvolume Supersymmetry and Intersecting Domain Walls in N=1 SQCD
A. Ritz, M. Shifman, A. Vainshtein
We study the worldvolume dynamics of BPS domain walls in N=1 SQCD with N_f=N flavors, and exhibit an enhancement of supersymmetry for the reduced moduli space associated with broke…
