Surface operators, dual quivers and contours
S. K. Ashok, S. Ballav, M. Billo' +5
We study half-BPS surface operators in four dimensional N=2 SU(N) gauge theories, and analyze their low-energy effective action on the four dimensional Coulomb branch using equivar…
Surface operators in 5d gauge theories and duality relations
S. K. Ashok, M. Billo, E. Dell'Aquila +4
We study half-BPS surface operators in 5d N=1 gauge theories compactified on a circle. Using localization methods and the twisted chiral ring relations of coupled 3d/5d quiver gaug…
Surface operators, chiral rings, and localization in N=2 gauge theories
S. K. Ashok, M. Billo, E. Dell'Aquila +4
We study half-BPS surface operators in supersymmetric gauge theories in four and five dimensions following two different approaches. In the first approach we analyze the chiral rin…
Sum rules for tetraquark decay coupling constants with broken SU(3) symmetry
V. Gupta, G. Sánchez-Colón, S. Rajpoot
We give sum rules for tetraquark decay coupling constants, taking into account the SU(3) symmetry breaking interactions to first order.
Decay coupling constant sum rules for tetraquarks with broken SU(3) symmetry
V. Gupta, G. Sánchez-Colón, S. Rajpoot
For tetraquarks of the form we give sum rules for their decay coupling constants, taking into account the SU(3) symmetry breaking interactions to first or…
Lepton flavor mixing in the Wolfenstein scheme
V. Gupta, G. Sánchez-Colón, S. Rajpoot +1
We mimic the Wolfenstein scheme of quark flavor mixing to describe neutrino oscillations in the standard model. We identify the parameter with the experimentally measured value…
