Finite size phase transitions in QCD with adjoint fermions
Guido Cossu, Massimo D'Elia
We perform a lattice investigation of QCD with three colors and 2 flavors of Dirac (staggered) fermions in the adjoint representation, defined on a 4d space with one spatial dimens…
On the phase diagram of the Higgs SU(2) model
C. Bonati, G. Cossu, A. D'Alessandro +2
The Higgs SU(2) model with fixed Higgs length is usually believed to have two different phases at high gauge coupling (β), separated by a line of first order transitions but not di…
A test of first order scaling in Nf =2 QCD: a progress report
C. Bonati, G. Cossu, M. D'Elia +2
We present the status of our analysis on the order of the finite temperature transition in QCD with two flavors of degenerate fermions. Our new simulations on large lattices suppor…
An update in monopole condensation in two-flavour Adjoint QCD
G. Lacagnina, G. Cossu, M. D'Elia +2
QCD with fermions in the adjoint representation (aQCD) is a model for which a deconfinement and a chiral phase transition take place at different temperatures. In this work, we pre…
Dual Superconductivity in G2 group
G. Cossu, M. D'Elia, A. Di Giacomo +2
We investigate the dual superconductivity mechanism in the exceptional group . This is a centerless group (no 't Hooft flux vortices are allowed) and we check for the presence…
Monopole condensation in two-flavour Adjoint QCD
G. Cossu, M. D'Elia, A. Di Giacomo +2
Two distinct phase transitions occur at different temperatures in QCD with adjoint fermions (aQCD): deconfinement and chiral symmetry restoration. In this model, quarks do no expli…
