Cascading from Supersymmetric Yang-Mills Theory to Confinement and Chiral Symmetry Breaking in Adjoint QCD
Eric D'Hoker, Thomas T. Dumitrescu, Efrat Gerchkovitz +1
We argue that adjoint QCD in 3+1 dimensions, with any gauge group and two Weyl fermion flavors (i.e. one adjoint Dirac fermion), confines and spontaneously breaks its chira…
Revisiting the Multi-Monopole Point of Gauge Theory in Four Dimensions
Eric D'Hoker, Thomas T. Dumitrescu, Efrat Gerchkovitz +1
Motivated by applications to soft supersymmetry breaking, we revisit the expansion of the Seiberg-Witten solution around the multi-monopole point on the Coulomb branch of pure $SU(…
Vortex-Strings in N=2 SQCD and Bulk-String Decoupling
Efrat Gerchkovitz, Avner Karasik
We study vortex-strings in four-dimensional N=2 supersymmetric SU(Nc)xU(1) gauge theories with Nf hypermultiplets in the fundamental representation of SU(Nc) and general U(1) charg…
New Vortex-String Worldsheet Theories from Supersymmetric Localization
Efrat Gerchkovitz, Avner Karasik
We use supersymmetric localization techniques to study the low-energy dynamics of BPS vortex-strings in four-dimensional N=2 theories. We focus on theories with SU(Nc)xU(1) gauge g…
Correlation Functions of Coulomb Branch Operators
Efrat Gerchkovitz, Jaume Gomis, Nafiz Ishtiaque +3
We consider the correlation functions of Coulomb branch operators in four-dimensional N=2 Superconformal Field Theories (SCFTs) involving exactly one anti-chiral operator. These ex…
The Exact Bremsstrahlung Function in N=2 Superconformal Field Theories
Bartomeu Fiol, Efrat Gerchkovitz, Zohar Komargodski
We propose an exact formula for the energy radiated by an accelerating quark in N=2 superconformal theories in four dimensions. This formula reproduces the known Bremsstrahlung fun…
Sphere Partition Functions and the Zamolodchikov Metric
Efrat Gerchkovitz, Jaume Gomis, Zohar Komargodski
We study the finite part of the sphere partition function of d-dimensional Conformal Field Theories (CFTs) as a function of exactly marginal couplings. In odd dimensions, this quan…
Constraints on the R-charges of Free Bound States from the Römelsberger Index
Efrat Gerchkovitz
The Römelsberger index on S^3 x R serves as a powerful test for conjectured dualities, relying on the claim that this object is an RG-invariant. In this work we support this claim…
