Glueball Calculations in Large-Nc Gauge Theory
We use the light-front Hamiltonian of transverse lattice gauge theory to compute from first principles the glueball spectrum and light-front wave functions in the leading order of the 1yNc color expansion. We find 0, 2, and 1 glueballs having masses consistent with Nc 3 data available from Euclidean lattice path integral methods. The wave functions exhibit a light-front constituent gluon stru...
متن کاملPseudoscalar Glueball Mass: QCD vs. Lattice Gauge Theory Prediction
We study whether the pseudoscalar glueball mass in full QCD can differ from the prediction of quenched lattice calculations. Using properties of the correlator of the vacuum topological susceptibility we derive an expression for the upper bound on the QCD glueball mass. We show that the QCD pseudoscalar glueball is lighter than the pure Yang-Mills theory glueball studied in quenched lattice cal...
متن کاملDynamical symmetry breaking on a brane with bulk gauge theory
We analyze a structure of dynamical chiral symmetry breaking in orbifold gauge theories with matter fields (fermions) on the fixed point. We find that the boundary chiral phase structure of QED and QCD on the orbifold is quite nontrivial depending on the bulk constitution, and we claim that particular attention should be given to the dynamically generated masses in various kinds of phenomenolog...
متن کاملHolomorphy and dynamical scales in supersymmetric gauge theories
New recent results in supersymmetric gauge theories based on holomorphy and symmetry considerations are extended to the case where the gauge coupling constant is given by the real part of a chiral superfield. We assume here that its dynamics can be described by an effective quantum field theory. Then its vacuum expectation value is a function of the other coupling constants, viewed as chiral ba...
متن کاملDynamical Fermions in Hamiltonian Lattice Gauge Theory
Nearly all lattice studies with dynamical fermions rely on pseudofermion techniques. This includes the standard Hybrid Monte Carlo method for non-local boson actions [1] and more recently multiboson methods proposed by Lüscher [2] and extended to odd flavors by Boriçi and de Forcrand [3]. While these methods are presently the most efficient available for dynamical fermion calculations, much imp...
