Thermal quarks and gluon propagators in two-color dense QCD

Understand

We study Landau gauge gluon propagators in two-color QCD at finite quark chemical potential ($\mu_q$) and temperature ($T$).

• We include medium polarization effects at one-loop by quarks into massive gluon propagators, and compared the analytic results with the available lattice data.
• We particularly focus on the high density phase of color-singlet diquark condensates whose critical temperature is $\sim 100$ MeV with weak dependence on $\mu_q$.
• At zero temperature the color singlet condensates protect the IR limit of electric and magnetic gluon propagators from the medium screening effects.
