Spontaneous Symmetry BreakingConsequences of gauging exact \\( {\\mathbb{Z}}_k^C \\) center symmetries in several simple SU(N) gauge theories, where k is a divisor of N, are investigated. Models discussed include: the SU(N) gauge theory with Nf copies of Weyl fermions in self-adjoint ...

1-form gauge symmetry Γ of the form (2) insix-dimensional gravitational theories with minimal su-persymmetry, going beyond the necessity for its gauging.Mostly focusing for concreteness on F-theory vacua, wewill constrain the structure of the 1-form gauge sector in6d N = (1,0) ...
String Gauge SymmetryRecently we have studied the instant-form quantization (IFQ) and the light-front quantization (LFQ) of the conformally gauge-fixed Polyakov D1 brane action using the Hamiltonian and path integral formulations. The IFQ is studied in the equal world-sheet time framework on ...
In Ref.[28], the authors derive exact relations between the two-particle and three-particle B-meson light-cone distribution amplitudes from the QCD equations of motion and heavy-quark symmetry. The two-particle B-meson light-cone distribution amplitudes have been studied with the QCD sum rules ...

four (3+1)-dimensions and a 3-form gauge theory in six (5+1)-dimensions of space-time, we establish that such gauge theories respect, in addition to the gauge symmetry transformations that are generated by the first-class constraints of the theory, additional continuous symmetry transformations...
For any F-theory vacua with at least one tensor multiplet, we derive the constraints from the P1 fibration structure of the base twofold and identify their physical origin in terms of the worldsheet symmetry of the associated effective heterotic string. The bounds are also extended to the F-...
7. 4.8 Isospin effects The whole calculation of the form factors has been done assuming isospin symmetry. The main effect of isospin breaking is to modify the endpoint of the chiral extrapolation through a change in the pion mass. This effect could bring the endpoint of the extrapolation ...
