The critical surface of the SU(3)_L x SU(3)_R chiral quark model at non-zero baryon density
P. Kovacs, Zs. Szep
The boundary of the first order chiral phase transition region is studied in the m_pi-m_K-mu_B space using the one-loop optimized perturbation theory for the resummation of the per…
The boundary of the first order chiral phase transition in the m_pi-m_K--plane with a linear sigma model
T. Herpay, Zs. Szep
Tree-level and complete one-loop parametrisation of the linear sigma model (LSM) is performed and the phase boundary between first order and crossover transition regions of the m_p…
Resummed one-loop determination of the phase boundary of the SU(3)_R x SU(3)_L linear sigma model in the m_pi-m_K-plane
T. Herpay, Zs. Szep
Complete one-loop parametrization of the linear sigma model is performed and the phase boundary between first order and crossover transition regions of the m_pi-m_K-plane is determ…
Progress on NNLO subtraction
Vittorio Del Duca, Gabor Somogyi, Zoltan Trocsanyi
We review standard subtraction, as a method to compute cross sections at NNLO accuracy.
