PHYSICS OF ELEMENTARY PARTICLES AND ATOMIC NUCLEI. THEORY

We revisit the classical aspects of N=(2,2) supersymmetric sigma models with Hermitian symmetric target spaces, using the so-called Gross–Neveu (“first-order GLSM”) formalism. We reformulate these models for complex Grassmannians in terms of simple supersymmetric Lagrangians with polynomial interactions. For maximal isotropic Grassmannians we propose two types of equivalent Lagrangians, which make either supersymmetry or the geometry ...

Search for NS 3-form flux-induced vacua for the critical non-abelian vortex string

It has been demonstrated that the non-Abelian solitonic vortex string in four-dimensional (4D) N=2 supersymmetric QCD (SQCD) with gauge group U(2) and Nf=4 quark hypermultiplets behaves as a critical superstring. This string propagates in a ten-dimensional space comprising the flat 4D space and an internal Calabi–Yau noncompact threefold, specifically, the conifold. The lowest state of this string is a ...
