“…5, with a sudden variation in the EOS, especially for lower value of x σ∆ . These abrupt changes in the EOS (which would become more smoothed with a parametrization on the energy dependence of µ B and T ) may be relevant in the planning of future compressed baryonic matter experiments [68,69,70].…”

We investigate an effective relativistic equation of state at finite values of temperature and baryon chemical potential with the inclusion of the full octet of baryons, the ∆-isobars and the lightest pseudoscalar and vector meson degrees of freedom. These last particles have been introduced within a phenomenological approach by taking into account of an effective chemical potential and mass depending on the self-consistent interaction between baryons. In this framework, we study of the hadron yield ratios measured in central heavy ion collisions over a broad energy range and present the beam energy dependence of underlying dynamic quantities like the net baryon density and the energy density.

“…The diagnostic probes of the matter created in the collisions include; (i) Short lived vector mesons (ρ, ω) decaying to dilepton pairs, (ii) Production of multi-strange hyperons (Ξ, Ω) (iii) Dissociation of Charmonium (J/Ψ) and charmed hadron (D, Λ c ) states, etc. The existence of first order phase transition from hadronic to partonic matter and restoration of chiral symmetry at the large µ B is expected to be found from the FAIR energy scan program [7]. Earlier experiments such as; RHIC-AGS and CERN-SPS were aimed to explore above features through the measurement of bulk observables like; flow and momentum spectra of hadrons.…”

The conditions of local thermodynamic equilibrium of baryons (non-strange, strange) and mesons (strange) are presented for central Au + Au collisions at FAIR energies using the microscopic transport model UrQMD. The net particle density, longitudinal-to-transverse pressure anisotropy and inverse slope parameters of the energy spectra of non-strange and strange hadrons are calculated inside a cell in the central region within rapidity window |y| < 1.0 at different time steps after the collisions. We observed that the strangeness content is dominated by baryons at all energies, however contribution from mesons become significant at higher energies. The time scale obtained from local pressure (momentum) isotropization and thermalization of energy spectra are nearly equal and found to decrease with increase in laboratory energy. The equilibrium thermodynamic properties of the system are obtained with statistical thermal model. The time evolution of the entropy densities at FAIR energies are found very similar with the ideal hydrodynamic behaviour at top RHIC energy.

“…These conditions can be naturally satisfied inside the core of neutron stars, where temperatures are relatively low compared to densities which can reach values several times the normal nuclear density and hence allow deconfinement. The conditions for a BCS-BEC crossover can also be expected to be met in the planned low-energy experiments at the Relativistic Heavy Ion Collider (RHIC) and future facilities all over the world, such as the Facility for Antiproton and Ion Research (FAIR) [3], the Nuclotron-Based Ion Collider Fcility (NICA), or the Japn Proton Accelerator Research Complex (J-PARC) [4].…”

Magnetic tuning of the relativistic BCS-BEC crossover

et al. 2011

The effect of an applied magnetic field in the crossover from Bose-Einstein condensate (BEC) to Bardeen-Cooper-Schrieffer (BCS) pairing regimes is investigated. We use a model of relativistic fermions and bosons inspired by those previously used in the context of cold fermionic atoms and in the magnetic-color-flavor-locking phase of color superconductivity. It turns out that as with cold atom systems, an applied magnetic field can also tune the BCS-BEC crossover in the relativistic case. We find that no matter what the initial state is at B = 0, for large enough magnetic fields the system always settles into a pure BCS regime. In contrast to the atomic case, the magnetic field tuning of the crossover in the relativistic system is not connected to a Feshbach resonance, but to the relative numbers of Landau levels with either BEC or BCS type of dispersion relations that are occupied at each magnetic field strength.
