Zwiegli\'nski Categories: nucl-ex Comments: 15 pages, 8 figures \\ The performance of the LAND neutron detector is studied. Using an event-mixing technique based on one-neutron data obtained in the S107 experiment at the GSI laboratory, we test the efficiency of various analytic tools used to determine the multiplicity and kinematic properties of detected neutrons. A new algorithm developed recently for recognizing neutron showers from spectator decays in the ALADIN experiment S254 is described in detail. Its performance is assessed in comparison with other methods. The properties of the observed neutron events are used to estimate the detection efficiency of LAND in this experiment. \\ ( http://arxiv.org/abs/1203.5608 , 114kb) ------------------------------------------------------------------------------ \\ arXiv:1203.5707 Date: Mon, 26 Mar 2012 16:01:35 GMT (5559kb,D) Title: Strangeness nuclear physics: a critical review on selected topics Authors: Elena Botta, Tullio Bressani, Gianni Garbarino Categories: nucl-ex nucl-th Comments: 63 pages, 51 figures, accepted for publication on European Physical Journal A \\ Selected topics in strangeness nuclear physics are critically reviewed. This includes production, structure and weak decay of $\Lambda$--Hypernuclei, the $\bar K$ nuclear interaction and the possible existence of $\bar K$ bound states in nuclei. Perspectives for future studies on these issues are also outlined. \\ ( http://arxiv.org/abs/1203.5707 , 5559kb) ------------------------------------------------------------------------------ \\ arXiv:1203.5756 Date: Mon, 26 Mar 2012 18:34:29 GMT (3603kb) Title: Study of the eta --> e+ e- gamma decay using WASA-at-COSY detector system Authors: Malgorzata Hodana Categories: nucl-ex Comments: Ph.D. Thesis (Advisor: Prof. Pawel Moskal), Jagiellonian University, Cracow 2012; Version includes minor corrections according to the comments of the referees \\ Since the eta meson is a short-lived neutral particle, it is not possible to investigate its structure via classical methods of particle scattering. To learn about its quark wave function, one studies those decay processes of this meson in which a pair of photons is produced, where at least one of them is virtual. The virtual photons have a non-zero mass and convert into lepton-antilepton pairs. Therefore, information about the quarks' spatial distribution inside the meson can be extracted from the lepton-antilepton invariant mass distributions by comparing the empirical results with QED predictions, which are based on the assumption that the meson is a point-like particle. The deviation from the expected behavior in the leptonic mass spectrum exposes the inner structure of the meson. This deviation is characterized by a form factor. The corresponding data were collected for the pd --> 3He eta reaction at a proton beam momentum of 1.69 GeV/c. The experiment was performed using the WASA-at-COSY detector in November 2008. 525 +/- 26 events of the eta --> g e+ e- decay channel were reconstructed. The analysis chain led to the determination of the value of the slope parameter, bp, equal to (2.27 +/- 0.73stat. +/- 0.46sys.) GeV^{-2}, where the systematical uncertainty should be treated as an upper limit only. The estimation of the charge radius of the eta meson has been made resulting with the value of < r(eta)^2 >^(1/2) = (0.68 +/- 0.02) fm. \\ ( http://arxiv.org/abs/1203.5756 , 3603kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1203.5341 (*cross-listing*) Date: Fri, 23 Mar 2012 20:00:10 GMT (2627kb) Title: Strong QCD and Dyson-Schwinger Equations Authors: Craig D. Roberts Categories: nucl-th hep-lat hep-ph nucl-ex Comments: 91 pages. Notes based on 5 lectures to the conference on "Dyson-Schwinger Equations & Fa\`a di Bruno Hopf Algebras in Physics and Combinatorics (DSFdB2011)", Institut de Recherche Math\'ematique Avanc\'ee, l'Universite de Strasbourg et CNRS, Strasbourg, France, 27.06-01.07/2011. To appear in "IRMA Lectures in Mathematics & Theoretical Physics," published by the European Mathematical Society (EMS) \\ The real-world properties of quantum chromodynamics (QCD) - the strongly-interacting piece of the Standard Model - are dominated by two emergent phenomena: confinement; namely, the theory's elementary degrees-of-freedom - quarks and gluons - have never been detected in isolation; and dynamical chiral symmetry breaking (DCSB), which is a remarkably effective mass generating mechanism, responsible for the mass of more than 98% of visible matter in the Universe. These phenomena are not apparent in the formulae that define QCD, yet they play a principal role in determining Nature's observable characteristics. Much remains to be learnt before confinement can properly be understood. On the other hand,the last decade has seen important progress in the use of relativistic quantum field theory, so that we can now explain the origin of DCSB and are beginning to demonstrate its far-reaching consequences. Dyson-Schwinger equations have played a critical role in these advances. These lecture notes provide an introduction to Dyson-Schwinger equations (DSEs), QCD and hadron physics, and illustrate the use of DSEs to predict phenomena that are truly observable. \\ ( http://arxiv.org/abs/1203.5341 , 2627kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1111.0883 (*cross-listing*) replaced with revised version Sat, 24 Mar 2012 08:36:27 GMT (216kb) Title: Effects of the U-boson on the inner edge of neutron star crusts Authors: Hao Zheng, Lie-Wen Chen Categories: nucl-th astro-ph.SR hep-ph nucl-ex Comments: 16 pages, 8 figures.
