Kirchbach, C. Compean Categories: nucl-th Comments: 13 pages, 2 figures; Invited talk at the "XXVII International Workshop on Nuclear Physics", Rila Mountains, Bulgaria, June 22-June 28, 2008 Journal-ref: Proceedings of the "XXVII Int. Workshop Nucl. Phys.", Rila Mountains, 2008, Sevdalina S. Dimitrova (Editor), pp. 129-142 \\ Non-perturbative methods of effective field theory such like Lattice QCD have allowed to establish connection between the QCD Lagrangian and quark potential models, a prominent outcome being the Cornell (linear plus Coulomb) potential. In being quite successful in explaining properties of heavy flavor hadrons, be them quarkonia or baryons, this potential has been found less spectacular in the description of the non-strange baryons, the nucleon and the Delta. This behavior indicates that the one-gluon exchange and the flux-tube interaction do not fully account for the complexity of the dynamics of three light quarks. Very recently, the Cornell potential which is of infinte range has been upgraded by us toward an exactly solvable trigonometric potential of finite range that interpolates between the inverse-distance potential and the infinite wells while passing through a region of linear growth, a reason for which it contains the inverse distance and the linear potentials as first terms in its Taylor series decomposition. We here first make the point that the upgraded Cornell potential can be viewed as the exact counterpart on a curved space to a flat space 1/r potential, a circumstance that equips it by two simultaneous symmetries, SO(4), and SO(2,1). These allow to place the trigonometric confinement potential in the context of AdS_5/CFT correspondence and thus to establish the link of the algebraic aspects of the latter to QCD potentiology. Next we report that the above potential when employed in the quark-diquark system, provides a remarkably adequate description of both nucleon and Delta spectra and the proton mean square charge radius as well, and moreover implies an intriguing venue toward quark deconfinement as shut-down of the curvature considered as temperature dependent. \\ ( http://arxiv.org/abs/0810.5124 , 37kb) ------------------------------------------------------------------------------ \\ arXiv:0810.5192 Date: Wed, 29 Oct 2008 04:13:38 GMT (74kb) Title: Causal dissipative hydrodynamics obtained from the nonextensive/dissipative correspondence Authors: Takeshi Osada and Grzegorz Wilk Categories: nucl-th Comments: 4 pages, 2 figures \\ We derive the constitutive equations of causal relativistic dissipative hydrodynamics ($d$-hydrodynamics) from perfect nonextensive hydrodynamics ($q$-hydrodynamics) using the nonextensive/dissipative correspondence (NexDC) proposed by us recently. The $q$-hydrodynamics can be thus regarded as a possible model for the $d$-hydrodynamics facilitating its application to high energy multiparticle production processes. As an example we have shown that applying the NexDC to the perfect 1+1 $q$-hydrodynamics, one obtains a proper time evolution of the bulk pressure and the Reynolds number. \\ ( http://arxiv.org/abs/0810.5192 , 74kb) ------------------------------------------------------------------------------ \\ arXiv:0810.5213 Date: Wed, 29 Oct 2008 08:10:11 GMT (46kb) Title: Nuclear Scissors with Pairing and Continuity Equation Authors: E. B. Balbutsev, L. A. Malov, P. Schuck, M. Urban Categories: nucl-th Comments: 28 pages, 3 figures \\ The coupled dynamics of the isovector and isoscalar giant quadrupole resonances and low lying modes (including scissors) are studied with the help of the Wigner Function Moments (WFM) method generalized to take into account pair correlations. Equations of motion for collective variables are derived on the basis of the Time Dependent Hartree-Fock-Bogoliubov (TDHFB) equations in the harmonic oscillator model with quadrupole-quadrupole (QQ) residual interaction and a Gaussian pairing force. Special care is taken of the continuity equation. \\ ( http://arxiv.org/abs/0810.5213 , 46kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:0808.1436 (*cross-listing*) Date: Mon, 11 Aug 2008 02:45:16 GMT (48kb) Title: The Asymmetric Superfluid Local Density Approximation (ASLDA) Authors: Aurel Bulgac, Michael McNeil Forbes Categories: cond-mat.supr-con cond-mat.other nucl-th Comments: 8 pages, RevTeX4, 6 figures \\ Here we describe the form of the Asymmetric Superfluid Local Density Approximation (ASLDA), a Density Functional Theory (DFT) used to model the two-component unitary Fermi gas.

H. Rezaeian, Zhun Lu Categories: hep-ph nucl-th Comments: 7 pages, 8 figures Report-no: USM-TH-239 \\ Pions and protons production cross-sections are analyzed in proton-proton and proton-nucleus collisions at the RHIC energy at midrapidity. We employ the pQCD factorization scheme supplemented with the color-dipole formalism to investigate the Cronin effect. In our approach, the Cronin effect is induced by transverse momentum broadening due to initial partons multi-scatterings. We calculate the broadening in the color-dipole approach in a parameter-free fashion for different centralities. Uncertainties in nuclear shadowing of various parton distributions and parton fragmentation functions are also discussed. \\ ( http://arxiv.org/abs/0810.4942 , 82kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:0710.3204 (*cross-listing*) replaced with revised version Wed, 29 Oct 2008 18:05:06 GMT (434kb) Title: Computational Model for Electron-Nucleon Scattering and Weak Charge of the Nucleon Authors: A.
