Keller, K. Hicks, and CLAS Collaboration Categories: nucl-ex hep-ex \\ The electromagnetic decay $\Sigma^0(1385) \to \Lambda \gamma$ was studied using the CLAS detector at the Thomas Jefferson National Accelerator Facility. A real photon beam with a maximum energy of 3.8 GeV was incident on a proton target, producing an exclusive final state of $K^+\Sigma^{*0}$. We report the decay widths ratio $\Sigma^0(1385) \to \Lambda\gamma$/ $\Sigma^0(1385) \to \Lambda\pi^0$ = $1.42 \pm 0.12(\text{stat})_{-0.07}^{+0.11}(\text{sys})$%. This ratio is larger than most theoretical predictions by factors ranging from 1.5-3, but is consistent with the only other experimental measurement. From the reported ratio we calculate the partial width and electromagnetic transition magnetic moment for $\Sigma^0(1385) \to \Lambda\gamma$. \\ ( http://arxiv.org/abs/1103.5701 , 247kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1103.5516 (*cross-listing*) Date: Tue, 29 Mar 2011 00:41:29 GMT (50kb) Title: $J/\Psi$-nuclear bound states Authors: K. Tsushima, D. H. Lu, G. Krein, A. W. Thomas Categories: nucl-th hep-ex hep-lat hep-ph nucl-ex Comments: 11 pages, 4 figures, 1 table Report-no: ADP-11-14/T736 \\ $J/\Psi$-nuclear bound state energies are calculated for a range of nuclei by solving the Proca (Klein-Gordon) equation. Critical input for the calculations, namely the medium-modified $D$ and $D^*$ meson masses, as well as the nucleon density distributions in nuclei, are obtained from the quark-meson coupling model. The attractive potential originates from the $D$ and $D^*$ meson loops in the $J/\Psi$ self-energy in nuclear medium. It appears that $J/\Psi$-nuclear bound states should produce a clear experimental signature provided that the $J/\Psi$ meson is produced in recoilless kinematics. \\ ( http://arxiv.org/abs/1103.5516 , 50kb) ------------------------------------------------------------------------------ \\ arXiv:1103.5710 (*cross-listing*) Date: Tue, 29 Mar 2011 17:04:29 GMT (221kb) Title: New Approaches to Target Mass Corrections Authors: F. M. Steffens Categories: hep-ph nucl-ex nucl-th Comments: 4 pages. Presented at HiX2010, Jlab, October 2010 \\ We analyze different prescriptions for the inclusion of target mass effects in the extraction of parton distributions from the measured structure functions. As a main result, the problem of defining parton distributions in the presence of mass is an open problem. \\ ( http://arxiv.org/abs/1103.5710 , 221kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1101.1701 (*cross-listing*) replaced with revised version Tue, 29 Mar 2011 07:35:55 GMT (136kb) Title: Effects of final state interactions on charge separation in relativistic heavy ion collisions Authors: Guo-Liang Ma and Bin Zhang Categories: nucl-th hep-ph nucl-ex Comments: 14 pages, 7 figures; v2: 3 figures added, discussions extended \\ ( http://arxiv.org/abs/1101.1701 , 136kb) %%%---%%%---%%%---%%%---%%%---%%%---%%%---%%%---%%%---%%%---%%%---%%%---%%%--- For subscribe options to combined physics archives, e-mail To: physics@arXiv.org, Subject: subscribe ----------------------------------------------------------------------------- For help on viewing and making submissions, see http://arXiv.org/help/ For a list of archive mirror sites, see http://arXiv.org/servers.html ----------------------------------------------------------------------------- Third-party submissions cause excessive problems.
