Cramer, et al. (310 additional authors not shown) Categories: nucl-ex \\ Azimuthal angular correlations of charged hadrons with respect to the axis of a reconstructed (trigger) jet in Au+Au and p+p collisions at $\sqrt{s_{NN}} = 200$ GeV in STAR are presented. The trigger jet population in Au+Au collisions is biased towards jets that have not interacted with the medium, allowing easier matching of jet energies between Au+Au and p+p collisions while enhancing medium effects on the recoil jet. The associated hadron yield of the recoil jet is significantly suppressed at high transverse momentum ($p_{T}^{assoc}$) and enhanced at low $p_{T}^{assoc}$ in Au+Au collisions, which is indicative of medium-induced parton energy loss in ultrarelativistic heavy-ion collisions. \\ ( http://arxiv.org/abs/1302.6184 , 78kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1302.5466 (*cross-listing*) Date: Fri, 22 Feb 2013 02:17:56 GMT (211kb) Title: Possible $\Sigma^*(1/2^-)$ in initial-state polarized $\gammaN\rightarrow K^{+} \Sigma^*(1385) \rightarrow K^{+} \pi \Lambda$reaction near threshold Authors: Yun-Hua Chen, Bing-Song Zou Categories: nucl-th hep-ph nucl-ex Comments: 15 pages, 5 figures \\ By using effective Lagrangian method, we study the effects of a newly proposed $\Sigma^*(1/2^-)$ state with mass around 1380 MeV in initial-state polarized $\gamma N\rightarrow K^{+} \Sigma^*(1385) \rightarrow K^{+} \pi \Lambda$ process near threshold. The theoretical predictions for the helicity cross sections $\sigma_{3/2}$, $\sigma_{1/2}$ as well as their ratios, and the the angular distributions of $\pi$ in the $\pi\Lambda$ c.m. system are given. It is found that assuming $\Sigma^*(1/2^-)$ exists or not, these physical quantities are distinctly different. So our results could be useful for the investigation of the existence of $\Sigma^*(1/2^-)$ when the experimental data are available in the future. \\ ( http://arxiv.org/abs/1302.5466 , 211kb) ------------------------------------------------------------------------------ \\ arXiv:1302.5873 (*cross-listing*) Date: Sun, 24 Feb 2013 05:36:24 GMT (45kb) Title: Towards detailed tomography of high energy heavy-ion collisions by $\gamma$-jet Authors: Guo-Liang Ma Categories: nucl-th hep-ph nucl-ex Comments: 4 pages, 4 figures \\ Within a multi-phase transport (AMPT) model with string melting scenario, the transverse momentum imbalance between prompt photon and jet is studied in Pb+Pb collisions at $\sqrt{s_{_{\rm NN}}}$ = 2.76 TeV. Jet losses its energy from by $\sim$15% in central collisions to by $\sim$ 5% in peripheral collisions due to strong interactions between jet and partonic matter, which is much higher than those from hadronic interactions only. The final hadronic interactions have little influence on the imbalance. The imbalance ratio, $x_{j\gamma}$, is very sensitive to both production position and passing direction of $\gamma$-jet, which enables a detail $\gamma$-jet tomographic study on the formed partonic matter by selecting different $x_{j\gamma}$ ranges experimentally. It is proposed that $\gamma$-hadron azimuthal correlation associated with $\gamma$+jet is a good probe to see the medium response to different $\gamma$-jet production configurations. \\ ( http://arxiv.org/abs/1302.5873 , 45kb) ------------------------------------------------------------------------------ \\ arXiv:1302.5959 (*cross-listing*) Date: Sun, 24 Feb 2013 21:47:52 GMT (501kb,D) Title: Recent results in chiral effective field theory for the NN system Authors: Daniel R. Phillips (Ohio University) Categories: nucl-th hep-ph nucl-ex Comments: Invited talk at the 7th International Workshop on Chiral Dynamics, August 6-10, 2012, Jefferson Lab, Newport News, VA. To appear in the proceedings. 12 pages, 5 figures \\ I describe recent progress towards a theory of the NN force which captures the consequences of QCD's chiral symmetry and the pattern of its breaking, and is formulated as an expansion in a ratio of low and high mass scales, M_{lo}/M_{hi}. This "chiral effective field theory" of the NN system is a firm foundation for explorations of nuclear structure and reactions that are grounded in QCD's low-energy symmetries. While calculations that use a ChiPT expansion for the NN potential have proven very successful, they can only be used with a narrow range of momentum-space cutoffs, which leaves the expansion parameter for observable quantities somewhat murky. Here we seek a truly systematic effective field theory for the NN amplitude, that is manifestly renormalization-group invariant at each order in a demonstrably perturbative expansion. \\ ( http://arxiv.org/abs/1302.5959 , 501kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1206.5414 (*cross-listing*) replaced with revised version Fri, 22 Feb 2013 10:38:10 GMT (232kb) Title: Eta-meson production in the resonance energy region Authors: V.
