The existence of a non-analytical behavior reminiscent of a phase transition for a characteristic size of the entangled region is demonstrated for higher dimensional theories. \\ ( http://arxiv.org/abs/0809.4502 , 65kb) ------------------------------------------------------------------------------ \\ arXiv:0809.4514 Date: Fri, 26 Sep 2008 00:14:21 GMT (88kb) Title: Spectroscopy with dynamical Chirally Improved quarks Authors: Christof Gattringer, C.

Gavai and Sayantan Sharma Categories: hep-lat Comments: 8 pages, 3 figures, talk presented at The XXVI International Symposium on Lattice Field Theory, July 14 - 19, 2008, Williamsburg, Virginia, USA Report-no: TIFR/TH/08-39 \\ Any mu^2-divergence is shown analytically to be absent for a class of actions for Overlap and Domain Wall Fermions with nonzero chemical potential. All such actions are, however, shown to violate the chiral invariance. While the parameter M of these actions can be shown to be irrelevant in the continuum limit, as expected, it is shown numerically that the continuum limit can be reached with relatively coarser lattices for M in the range of 1.5-1.6. \\ ( http://arxiv.org/abs/0809.4535 , 98kb) ------------------------------------------------------------------------------ \\ arXiv:0809.4563 Date: Fri, 26 Sep 2008 08:50:08 GMT (5kb) Title: Monopoles and the 't Hooft tensor for generic gauge group Authors: A. Di Giacomo, L. Lepori, F. Pucci Categories: hep-lat Comments: 3 pages. Poster presented at the International Conference on High Energy Physics ICHEP08. To appear in the Proceedings Report-no: IFUP-TH / 2008-30 \\ We study monopoles and corresponding 't Hooft tensor in a generic gauge theory. This issue is relevant to the understanding of color confinement. \\ ( http://arxiv.org/abs/0809.4563 , 5kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:0809.3450 (*cross-listing*) Date: Sun, 21 Sep 2008 03:24:10 GMT (36kb) Title: Non-Gaussian fluctuations near the QCD critical point Authors: M.A. Stephanov Categories: hep-ph hep-lat nucl-th Comments: 4 pages, 3 figures \\ We study the effect of the QCD critical point on non-Gaussian moments (cumulants) of fluctuations of experimental observables in heavy-ion collisions. We find that these moments are very sensitive to the proximity of the critical point, as measured by the magnitude of the correlation length xi. For example, the cubic central moment of multiplicity ~ xi^4.5 and the quartic cumulant ~ xi^7. We estimate the magnitude of critical point contributions to non-Gaussian fluctuations of pion and proton multiplicities. \\ ( http://arxiv.org/abs/0809.3450 , 36kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:0807.1390 replaced with revised version Thu, 25 Sep 2008 21:30:21 GMT (49kb) Title: Casimir scaling in G(2) lattice gauge theory Authors: L.
