Shear viscosity at finite baryon densities
We use the excluded volume Hadron Resonance Gas (HRG) model with the most up-to-date hadron list to calculate η T/w at low temperatures and at finite baryon densities ρ B . This η T/w is then matched to a QCD-based shear viscosity calculation of the QGP for different profiles of η T/w across T,μ B including cross-over and critical point transitions. When compared to ideal hydrodynamic trajectories across T,μ B , we find that the η T/w (T,μ B ) profiles would require initial conditions at much larger baryon density to reach the same freeze-out point.

1. A bstract This article presents differential measurements of the asymmetry between $${\varLambda}_b^0$$ Λ b 0 and $${\overline{\varLambda}}_b^0$$ Λ ¯ b 0 baryon production rates in proton-proton collisions at centre-of-mass energies of $$\sqrt{s}$$ s = 7 and 8 TeV collected with the LHCb experiment, corresponding to an integrated luminosity of 3 fb − 1 . The $${\varLambda}_b^0$$ Λ b 0 baryons are reconstructed through the inclusive semileptonic decay $${\varLambda}_b^0$$ Λ b 0 → $${\varLambda}_c^{+}$$ Λ c + μ − $$\overline{\nu}$$ ν ¯ μ X . The production asymmetry is measured both in intervals of rapidity in the range 2 . 15 < y < 4 . 10 and transverse momentum in 2 < p T < 27 GeV/ c . The results are found to be incompatible with symmetric production with a significance of 5.8 standard deviations for both $$\sqrt{s}$$ s = 7 and 8 TeV data, assuming no CP violation in the decay. There is evidence for a trend as a function of rapidity with a significance of 4 standard deviations. Comparisons to predictions from hadronisation models in P ythia and heavy-quark recombination aremore »
3. Abstract We report on the inclusive $$\text {J}/\psi$$ J / ψ production cross section measured at the CERN Large Hadron Collider in proton–proton collisions at a center-of-mass energy $$\sqrt{s}~=~13$$ s = 13  TeV. The $$\text {J}/\psi$$ J / ψ mesons are reconstructed in the $$\text {e}^{+}\text {e}^{-}$$ e + e - decay channel and the measurements are performed at midrapidity ( $$|y|<0.9$$ | y | < 0.9 ) in the transverse-momentum interval 0more »
