Gluon-condensation of quark-gluon plasma in mean field approximation

Abstract: Starting from the field equations of QCD and applymg the mean field approxamatlon, a self-consistent set of equations is denved for the description of the gluon-condensed state of quark-gluon plasma A solution of these equations has been found, wtuch corresponds to a static, chromo-magnetic field, periodic in space. Ttus field reduces self-consistently a periodic oscdlatlon of the spin-color density of the quarks

“…For the reasons mentioned above, a complete solution for the RS equation under the influence of magnetic fields deserves a detailed revision, which we perform in the present work. We next follow the approach developed in [32] and [33] and circumvent the problems just mentioned, without having to rely on nonminimal couplings. To the best of our knowledge, this is the first time that a complete calculation of the Rarita-Schwinger equation with the inclusion of the magnetic interaction, including the occupation of the LL, is obtained in a simple way, avoiding the problems observed in older calculations.…”

“…Encontramos uma Lagrangiana efetiva escrita em termos do campo dos hard gluons, do campo dos quarks, das constantes µ 0 e φ 0 e da constante de acoplamento dos hard gluons g h (g s foi incorporada aos valores esperados dos campos dos soft gluons no QGP). Agora, para o campo dos hard gluons, α a µ , faremos a aproximação de campo médio do tipo "Walecka" [53,54], conforme já aplicado para a QCD em [55,56]. O plasma de quarks e gluons frio tem densidade muito maior do que a matéria nuclear, implicando num grande número de fontes para o campo dos hard gluons, os quais têm grande número de ocupação em todos os níveis de energia e, portanto, podem ser tratado como campos clássicos.…”
