High-density nuclear matter with nonlocal confining solitons
An infinite system of nonlocal, individually confining solitons is considered
as a model of high-density nuclear matter. The soliton-lattice problem is
discussed in the Wigner-Seitz approximation. The cell size is varied to study
the density dependence of physical quantities of interest. A transition to a
system where quarks can migrate between solitons is found. We argue that this
signals quark deconfinement. The model is applied to the calculation of
selected in-medium properties.Comment: 23 pages with 10 figure
From di-hadron correlations to parton intrinsic transverse momentum in proton-proton collisions
Di-hadron correlations in proton-proton collisions at s^1/2 = 200 GeV are
interpreted in terms of a fragmentation width and a momentum imbalance. A
fragmentation width of 580 +- 50 GeV/c is obtained, and the momentum imbalance
gives an `intrinsic' transverse momentum width of partons in the proton of 2.6
+- 0.2 GeV/c.Comment: Talk given at 2nd International Conference on Hard and
