Renormalization of 2PI resummation: a renormalization scheme approach
A. Jakovac
A practical method is suggested for performing renormalized 2PI resummation at finite temperature using specific momentum dependent renormalization schemes. In this method there is…
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…
From di-hadron correlations to parton intrinsic transverse momentum in proton-proton collisions
G. Fai, P. Levai, G. Papp
Di-hadron correlations in proton-proton collisions at s^1/2 = 200 GeV are interpreted in terms of a fragmentation width and a momentum imbalance. A fragmentation width of 580 +- 50…
Jet Tomography in the Forward Direction at RHIC
G. G. Barnaföldi, P. Lévai, G. Papp +1
Hadron production at high- displays a strong suppression pattern in a wide rapidity region in heavy ion collisions at RHIC energies. This finding indicates the presence of str…
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…
