On the chiral perturbation theory for two-flavor two-color QCD at finite chemical potential

Result description

We constructed the chiral perturbation theory for two-color QCD with two quark flavors as an effective theory on the SO(6)/SO(5) coset space. This formulation turns out to be very convenient for extracting the physical content of the theory when finite chemical potential is introduced. In particular, we proved a previous conjecture about the form of the ground state of the Bose-Einstein condensed pion gas.

    K chiralni poruchove teorii pro dvojflavorovou dvojbarevnou QCD pri konecnem chemickem potencialu]

  • Czech description

    Zkonstruovali jsme chirální poruchovou teorii pro dvoubarevnou QCD s dvěma kvarkovými vůněmi jako efektivní teorii na kosetovém prostoru SO(6)/SO(5). Tato formulace se ukazuje být vhodná pro identifikaci fyzikálních stupňů volnosti, obzvláště při nenulovém chemickém potenciálu. Speciálně se nám podařilo odvodit dříve navržený tvar základního stavu systému s pionovým kondenzátem.
