Oyama, for the ALICE Collaboration Categories: nucl-ex hep-ex physics.acc-ph physics.ins-det Comments: An updated version of proceedings contribution for workshop "LHC Lumi Days 2012", 29 Feb. (2012) at CERN. 11 pages, 8 figures \\ Cross sections of reference trigger processes were obtained based on beam property measurements in dedicated luminosity calibration experiments (van der Meer scans). These cross-sections are essential for absolute cross section determinations of physics processes. The reference cross sections are presented for pp collisions at two center of mass energies; 2.76 TeV and 7 TeV, and for Pb-Pb collisions at 2.76 TeV together with a discussion of the systematic uncertainty originating from beam intensity and rate measurement uncertainties. \\ ( http://arxiv.org/abs/1305.7044 , 1348kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1305.6959 (*cross-listing*) Date: Wed, 29 May 2013 21:24:57 GMT (106kb,D) Title: Charge form factor and sum rules of electromagnetic response functions in Carbon-12 Authors: A. Lovato, S. Gandolfi, Ralph Butler, J. Carlson, Ewing Lusk, Steven C. Pieper, and R. Schiavilla Categories: nucl-th nucl-ex Comments: 5 pages, 3 figures \\ An "ab initio" calculation of the Carbon-12 elastic form factor, and sum rules of longitudinal and transverse response functions measured in inclusive (e,e') scattering, is reported, based on realistic nuclear potentials and electromagnetic currents. The longitudinal elastic form factor and sum rule are found to be in satisfactory agreement with available experimental data. A direct comparison between theory and experiment is difficult for the transverse sum rule. However, it is shown that the calculated one has large contributions from two-body currents, indicating that these mechanisms lead to a significant enhancement of the quasi-elastic transverse response. This fact may have implications for the anomaly observed in recent neutrino quasi-elastic charge-changing scattering data off Carbon-12. \\ ( http://arxiv.org/abs/1305.6959 , 106kb) ------------------------------------------------------------------------------ \\ arXiv:1305.7101 (*cross-listing*) Date: Thu, 30 May 2013 13:29:13 GMT (643kb,D) Title: Neutron Skins and Neutron Stars Authors: J. Piekarewicz Categories: nucl-th astro-ph.SR nucl-ex Comments: 4 pages, 3 figures, submitted to the Proceedings of the "Workshop to Explore Physics Opportunities with Intense, Polarized Electron Beams up to 300 MeV" Report-no: FSU-NuclearTheory-05302013 \\ The neutron-skin thickness of heavy nuclei provides a fundamental link to the equation of state of neutron-rich matter, and hence to the properties of neutron stars. The Lead Radius Experiment ("PREX") at Jefferson Laboratory has recently provided the first model-independence evidence on the existence of a neutron-rich skin in 208Pb. In this contribution we examine how the increased accuracy in the determination of neutron skins expected from the commissioning of intense polarized electron beams may impact the physics of neutron stars. \\ ( http://arxiv.org/abs/1305.7101 , 643kb) ------------------------------------------------------------------------------ \\ arXiv:1305.7142 (*cross-listing*) Date: Thu, 30 May 2013 15:34:00 GMT (38kb) Title: Observing light-by-light scattering at the Large Hadron Collider Authors: David d'Enterria and Gustavo G. Silveira Categories: hep-ph hep-ex nucl-ex nucl-th Comments: 6 pages, 3 figures \\ Elastic light-by-light scattering (gamma-gamma-->gamma-gamma) can be observed at the Large Hadron Collider thanks to the large quasi-real photon fluxes available in electromagnetic interactions of protons (p) and lead (Pb) ions. The gamma-gamma-->gamma-gamma cross sections for diphoton masses m_gammagamma > 5 GeV amount to 12 fb, 26 pb, and 35 nb in p-p, p-Pb, and Pb-Pb collisions at nucleon-nucleon center-of-mass energies sqrt(s_NN) = 14 TeV, 8.8 TeV, and 5.5 TeV respectively. Such a measurement has no substantial backgrounds in Pb-Pb collisions where one expects about 20 signal events per run, after typical detector acceptance and reconstruction efficiency selections. \\ ( http://arxiv.org/abs/1305.7142 , 38kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1301.0880 replaced with revised version Thu, 30 May 2013 07:50:06 GMT (326kb) Title: Dependence of asymmetries for charge distribution with respect to the reaction plane on initial energy in heavy ion collisions Authors: V.A.
