Spinodal instabilities and early growth of baryon density fluctuations in symmetric nuclear matter are investigated in the basis of the stochastic extension of the relativistic mean-field approach in the semiclassical approximation. Calculations are compared with the results of nonrelativistic calculations based on Skyrme-type effective interactions under similar conditions. A qualitative difference appears in the unstable response of the system: the system exhibits most unstable behavior at higher baryon densities around rho(b) = 0.4 rho(0) in the relativistic approach while most unstable behavior occurs at lower baryon densities around rho(b) = 0.2 rho(0) in the nonrelativistic calculations

Spinodal instabilities in symmetric nuclear matter within a nonlinear relativistic mean-field approach
Acar, Fatma; Yılmaz, Osman; Department of Physics (2011)
Spinodal instability mechanism and early development of density fluctuations for symmetric nuclear matter at finite temperature are studied. A stochastic extension of Walecka-type relativistic mean-field model including non-linear self-interactions of scalar mesons with NL3 parameter set is employed in the semi-classical approximation. The growth rates of unstable collective modes are investigated below the normal density and at low temperatures. The system exhibits most unstable behavior in longer wave len...
Nuclear modification factor of D-0 mesons in PbPb collisions at root s(NN)=5.02 TeV
Sirunyan, A. M.; et. al. (Elsevier BV, 2018-07-01)
The transverse momentum (p(T)) spectrum of prompt D-0 mesons and their antiparticles has been measured via the hadronic decay channels D-0 -> K- pi(+) and (D) over bar (0) -> K+ pi(-) in pp and PbPb collisions at a centre-of-mass energy of 5.02 TeV per nucleon pair with the CMS detector at the LHC. The measurement is performed in the D-0 meson p(T) range of 2-100GeV/c and in the rapidity range of vertical bar y vertical bar < 1. The pp (PbPb) dataset used for this analysis corresponds to an integrated lumin...
Angular coefficients of Z bosons produced in pp collisions at root S=8 TeV and decaying to mu(+)mu(-) as a function of transverse momentum and rapidity
Khachatryan, V.; et. al. (Elsevier BV, 2015-11-01)
Measurements of the five most significant angular coefficients, A(0) through A(4), for Z bosons produced in pp collisions at root S = 8 TeV and decaying to mu(+)mu(-) are presented as a function of the transverse momentum and rapidity of the Z boson. The integrated luminosity of the dataset collected with the CMS detector at the LHC corresponds to 19.7 fb(-1). These measurements provide comprehensive information about the Z boson production mechanisms, and are compared to the QCD predictions at leading orde...
Thermodynamics of Lifshitz black holes
Devecioglu, Deniz Olgu; Sarıoğlu, Bahtiyar Özgür (American Physical Society (APS), 2011-06-23)
We apply the recently extended conserved Killing charge definition of Abbott-Deser-Tekin formalism to compute, for the first time, the energies of analytic Lifshitz black holes in higher dimensions. We then calculate the temperature and the entropy of this large family of solutions, and study and discuss the first law of black hole thermodynamics. Along the way we also identify the possible critical points of the relevant quadratic curvature gravity theories. Separately, we also apply the generalized Killin...
Investigations of spinodal dynamics in asymmetric nuclear matter within a stochastic relativistic model
Yılmaz, Osman; ACAR, FERİDE PINAR; Saatci, S.; GÖKALP, AHMET (Springer Science and Business Media LLC, 2013-03-01)
Early development of spinodal instabilities and density correlation functions in asymmetric nuclear matter are investigated in the stochastic extension of the Walecka-type relativistic mean field including coupling with rho meson. Calculations are performed under typical conditions encountered in heavy-ion collisions and in the crusts of neutron stars. In general, growth of instabilities occur relatively slower for increasing charge asymmetry of matter. At higher densities around rho = 0.4 rho(0) fluctuatio...
