Three-dimensional sizes of the system (femtoscopic radii), as well as direction-averaged one-dimensional radii are extracted. The radii decrease with $k_{\rm T}$, following a power-law behavior. This is qualitatively consistent with expectations from a collectively expanding system, produced in hydrodynamic calculations. The radii also scale linearly with $\left< \mathrm{d}N_{\rm ch}/\mathrm{d}\eta \right>^{1/3}$. This behaviour is compared to world data on femtoscopic radii in heavy-ion collisions. While the dependence is qualitatively similar to results at smaller $\sqrt{s_{\rm NN}}$, a decrease in the $R_{\rm out}/R_{\rm side}$ ratio is seen, which is in qualitative agreement with specific predictions from hydrodynamic models. The results provide further evidence for the production of a collective, strongly coupled system in heavy-ion collisions at the LHC. \\ ( http://arxiv.org/abs/1507.06842 , 170kb) ------------------------------------------------------------------------------ \\ arXiv:1507.06895 Date: Fri, 24 Jul 2015 15:48:53 GMT (24kb) Title: Novel technique to extract experimental symmetry free energy information of nuclear matter Authors: J. Mabiala, H. Zheng, A. Bonasera, P. Cammarata, K. Hagel, L. Heilborn, Z. Kohley, L. W. May, A. B. McIntosh, M. D. Youngs, A. Zarrella, and S. J. Yennello Categories: nucl-ex nucl-th Comments: 6 pages, 3 figures Heavy-ion nuclear reactions at Fermi energies, Nuclear equation of State, Fragmentation \\ A new method of accessing information on the symmetry free energy from yields of fragments produced in Fermi-energy heavy-ion collisions is proposed. Furthermore, by means of quantum fluctuation analysis techniques, correlations between extracted symmetry free-energy coefficients with temperature and density were studied. The obtained results are consistent with those of commonly used isoscaling techniques. \\ ( http://arxiv.org/abs/1507.06895 , 24kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1507.06607 (*cross-listing*) Date: Wed, 22 Jul 2015 11:20:27 GMT (210kb) Title: Fayans functional for deformed nuclei. Uranium region Authors: S.V. Tolokonnikov, I.N. Borzov, M. Kortelainen, Yu.S. Lutostansky and E.E. Saperstein Categories: nucl-th nucl-ex Comments: 6 pages, 9 figures, to appear in the proceedings of the International Conference "Nuclear Structure and Related Topics", July 14 - July 18, 2015, Dubha, Russia \\ Fayans energy density functional (EDF) FaNDF^0 has been applied to the nuclei around uranium region. Ground state characteristics of the Th, U and Pu isotopic chains, up to the two-neutron drip line, are found and compared with predictions from several Skyrme EDFs. The two-neutron drip line is found for FaNDF^0, SLy4 and SkM^* EDFs for a set of elements with even proton number, from Pb up to Fm. \\ ( http://arxiv.org/abs/1507.06607 , 210kb) ------------------------------------------------------------------------------ \\ arXiv:1507.06742 (*cross-listing*) Date: Fri, 24 Jul 2015 04:39:20 GMT (133kb,D) Title: Constraining heavy quark energy loss using $B$ and $D$ meson measurements in heavy ion collision at RHIC and LHC energies Authors: Kapil Saraswat, Prashant Shukla, Venktesh Singh Categories: nucl-th hep-ph nucl-ex Comments: 25 pages, 14 figures \\ In this work, we calculate energy loss of heavy quark (charm and bottom) due to elastic collisions and gluon radiation in hot/dense medium. The collisional energy loss has been obtained using QCD calculations. The radiative energy loss is calculated using reaction operator formalism and generalized dead cone approach. We rederive the energy loss expression using same assumptions as generalized dead cone approach but obtain slightly different results. We also improve the model employed to calculate path length and the system evolution. The nuclear modification factors $R_{AA}$ including shadowing and energy loss are evaluated for $B$ and $D$ mesons and are compared with the measurements in PbPb collision at $\sqrt{s_{NN}}$ = 2.76 TeV and with the Heavy flavour (HF) electrons measurements in AuAu collision at $\sqrt{s_{NN}}$ = 200 GeV. The radiative energy loss calculated by reaction operator formalism added with collisional energy loss describes the RHIC HF electron suppression in high $p_{T}$ range. It also describes the LHC measurement of $B$ meson suppression but overestimates the suppression of $D$ meson. The radiative energy loss from generalized dead cone approach describes the charm suppression at both RHIC as well as LHC energies and requires energy loss due to collisions to be added in order to describe the bottom suppression at LHC. \\ ( http://arxiv.org/abs/1507.06742 , 133kb) ------------------------------------------------------------------------------ \\ arXiv:1507.06972 (*cross-listing*) Date: Fri, 24 Jul 2015 19:39:56 GMT (200kb,AD) Title: Precocious suppression of baryon diffusion and transport in a baryon rich strongly coupled quark-gluon plasma Authors: Romulo Rougemont (Sao Paulo U.), Jorge Noronha (Sao Paulo U. & Columbia U.) Categories: hep-ph hep-th nucl-ex nucl-th Comments: 6 pages, 1 figure, tabulated data for the baryon conductivity can be obtained as an ancillary file \\ Five dimensional black hole solutions that describe the QCD crossover transition seen in (2+1)-flavor lattice QCD calculations at nonzero baryon densities are used to obtain predictions for the baryon susceptibility, baryon conductivity, baryon diffusion constant, and thermal conductivity of the strongly coupled quark-gluon plasma in the range of temperatures $T=130-300$ MeV and baryon chemical potentials $\mu_B=0-400$ MeV. Diffusive transport is predicted to be already suppressed in this region of the QCD phase diagram in a way that is consistent with the existence of a critical end point at larger baryon densities. \\ ( http://arxiv.org/abs/1507.06972 , 200kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1412.4092 (*cross-listing*) replaced with revised version Fri, 24 Jul 2015 17:24:05 GMT (563kb,D) Title: Centrality and rapidity dependence of inclusive jet production in $\sqrt{s_\mathrm{NN}} = 5.02$ TeV proton-lead collisions with the ATLAS detector Authors: ATLAS Collaboration Categories: hep-ex nucl-ex Comments: 14 pages plus author list + cover pages (30 pages total), 7 figures, 1 table, submitted to Phys.
