Phase structure of compactified gauge theories in magnetic backgrounds
Massimo D'Elia, Marco Mariti
We discuss the properties of non-abelian gauge theories formulated on manifolds with compactified dimensions and in the presence of fermionic fields coupled to magnetic backgrounds…
Recent progress on QCD inputs for axion phenomenology
Claudio Bonati, Massimo D'Elia, Marco Mariti +5
The properties of the QCD axion are strictly related to the dependence of strong interactions on the topological parameter theta. We present a determination of the topological prop…
Higher order quark number fluctuations via imaginary chemical potentials in QCD
Massimo D'Elia, Giuseppe Gagliardi, Francesco Sanfilippo
We discuss analytic continuation as a tool to extract the cumulants of the quark number fluctuations in the strongly interacting medium from lattice QCD simulations at imaginary ch…
Across the deconfinement
Claudio Bonati, Massimo D'Elia, Marco Mariti +3
The deconfinement transition at vanishing chemical potential can be reliably studied by lattice simulations and its general features are by now well known. On the contrary, what ha…
Magnetic field effects on the static quark potential at zero and finite temperature
Claudio Bonati, Massimo D'Elia, Marco Mariti +4
We investigate the static potential at zero and finite temperature in the presence of a constant and uniform external magnetic field , for several values of the…
dependence of 4D gauge theories in the large- limit
Claudio Bonati, Massimo D'Elia, Paolo Rossi +1
We study the large- scaling behavior of the dependence of the ground-state energy density of four-dimensional (4D) gauge theories and two-dimensional (2D) $CP…
