The light spectrum near the Argyres - Douglas point
نویسنده
چکیده
We consider N = 2 super Yang-Mills theory with SU(2) gauge group and a single quark hypermultiplet in the fundamental representation. For a specific value of the quark bare mass and at a certain point in the moduli space of vacua, the central charges corresponding to two mutually non-local electro-magnetic charges vanish simultaneously, indicating the possibility of massless such states in the spectrum. By realizing the theory as an M -theory configuration, we show that these states indeed exist in the spectrum near the critical point.

Condensates near the Argyres - Douglas point in SU ( 2 ) gauge theory with broken N = 2 supersymmetry
The behaviour of the chiral condensates in the SU(2) gauge theory with broken N=2 supersymmetry is reviewed. The calculation of monopole, dyon, and charge condensates is described. It is shown that the monopole and charge condensates vanish at the Argyres-Douglas point where the monopole and charge vacua collide. This phenomenon is interpreted as a deconfinement of electric and magnetic charges...
متن کاملBPS Structure of Argyres–Douglas Superconformal Theories
We study geometric engineering of Argyres–Douglas superconformal theories realized by type IIB strings propagating in singular Calabi–Yau threefolds. We use this construction to count the degeneracy of light BPS states under small perturbations away from the conformal point, by computing the degeneracy of D3–branes wrapped around supersym-metric 3–cycles in the Calabi–Yau. We find finitely many...
متن کاملDistribution of Flux Vacua around Singular Points in Calabi-Yau Moduli Space
We study the distribution of type IIB flux vacua in the moduli space near various singular loci, e.g. conifolds, ADE singularities on P, Argyres-Douglas point etc, using the AshokDouglas density det(R+ω). We find that the vacuum density is integrable around each of them, irrespective of the type of the singularities. We study in detail an explicit example of an Argyres-Douglas point embedded in...
متن کاملBPS spectrum of Argyres-Douglas theory via spectral network
We study the BPS spectrum of four-dimensional N = 2 superconformal field theory of Argyres-Douglas type, obtained via twisted compactification of six-dimensional AN−1 (2, 0) theory on a sphere with an irregular puncture, by using spectral networks. We give strong evidence of the equivalence of N = 2 superconformal field theories from sixdimensional theories of different ranks by systematically ...
متن کاملDeconfinement at the Argyres - Douglas point in SU ( 2 ) gauge theory with broken N = 2 supersymmetry
We consider chiral condensates in SU(2) gauge theory with broken N= 2 super-symmetry. The matter sector contains an adjoint multiplet and one fundamental flavor. Matter and gaugino condensates are determined by integrating out the ad-joint field. The only nonperturbative input is the Affleck-Dine-Seiberg (ADS) super-potential generated by one instanton plus the Konishi anomaly. These results ar...
