The behavior of kaons and pions in strange quark matter, simulating neutron matter in weak equilibrium, is investigated within the SU(3) Nambu-Jona-Lasinio [NJL] model. The system exhibits a first order phase transition, having a hadronic phase (quark droplets) at the critical density rho_c...
Define charm quark. charm quark synonyms, charm quark pronunciation, charm quark translation, English dictionary definition of charm quark. n. Abbr. c The flavor of quark that has a charge of + 2/3 , has a mass about 2,450 times that of an electron, and
The latter transition may be induced by a relatively small change in compound composition (cf. the behavior of La2 − xSrxO4 or YBa2Cu3O7 − x as a function of x). It is quite interesting to note that oxides such as YBa2Cu3O7 − x may be synthesized in either insulating (x ...

Different hadron transverse momentum spectra are calculated in a non-extensive statistical, quark-coalescence model. For the low-pT part a gluonic string contribution is conjectured, its length distribution and fractality are fitted to RHIC data.Biro, T S; Urmossy, K...
Fragmentation functions of pions and kaons in the nonlocal chiral quark modelunpolarized pion and kaon fragmentation functionschiral-quark modelrelatively good agreementWe investigate the unpolarized pion and kaon fragmentation functions using the nonlocal chiral-quark model. In this model the interactions ...
We describe the Mott dissociation of pions and kaons within a Beth-Uhlenbeck approach based on the Polyakov-loop improved Nambu–Jona-Lasinio model, which allows for a unified description of bound, resonant and scattering states. Within this model we evaluate the temperature and chemical potential ...
pionskaonsElectro-production of pions and kaons at the kinematics of quasi-elastic knockout (which is well known in the physics of atomic nucleus and corresponds to the t-pole diagram) is proposed for obtaining their momentum distribution (MD) in various channels of virtual decay NrarrB+pi, ...
The change in the composition of the system from a hadron resonance gas to a quark–gluon plasma takes place in the narrow temperature interval of 150–190 MeV, where the Mott dissociation of hadrons is triggered by the dropping quark mass as a result of the restoration of chiral symmetry....
