Scaling properties of SU(2) gauge theory with mixed fundamental-adjoint action
Enrico Rinaldi, Giuseppe Lacagnina, Biagio Lucini +2
We study the phase diagram of the SU(2) lattice gauge theory with fundamental-adjoint Wilson plaquette action. We confirm the presence of a first order bulk phase transition and we…
Light scalar spectrum in extra-dimensional gauge theories
Enrico Rinaldi, Luigi Del Debbio, Alistair Hart
The phase diagram of five-dimensional SU(2) gauge theories with one compactified dimension on anisotropic lattices has a rich structure. In this contribution we show how to control…
Towards the glueball spectrum from unquenched lattice QCD
E. Gregory, A. Irving, B. Lucini +4
We use a variational technique to study heavy glueballs on gauge configurations generated with 2+1 flavours of ASQTAD improved staggered fermions. The variational technique include…
The glueball spectrum at large N
Biagio Lucini, Antonio Rago, Enrico Rinaldi
The lowest-lying glueball masses are computed in SU() gauge theory on a spacetime lattice for constant value of the lattice spacing and for ranging from 3 to 8. The latt…
