Polyakov loops and finite-size effects of hadron masses in full lattice QCD

Polyakov type loops are responsible for the difference between quenched and unquenched finite size effects on the QCD mass spectrum. With a numerical simulation, using appropriate sea quark spatial boundary conditions, we show that we can align the phases of spatial Polyakov loops in a predelined di...

Resumo:Polyakov type loops are responsible for the difference between quenched and unquenched finite size effects on the QCD mass spectrum. With a numerical simulation, using appropriate sea quark spatial boundary conditions, we show that we can align the phases of spatial Polyakov loops in a predelined direction. Starting from these results, we propose a procedure to minimize fluctuations due to these effects in meson propagators.
