چکیده
Two-particle correlation functions are calculated for bosons emitted from a localized thermal source (the “glow” of a “hot spot”). In contrast to existing work, non-equilibrium effects up to first order in gradients of the particle distribution function are taken into account. The spectral width of the bosons is shown to be an important quantity: If it is too small, they do not equilibrate locally and therefore strongly increase the measured correlation radius. In memoriam of Eugene Wigner and Hiroomi Umezawa.

The evolution of dynamical perturbations is examined in nuclear multifragmentation in the frame of Vlasov equation. Both plane wave and bubble type of perturbations are investigated in the presence of surface (Yukawa) forces. An energy condition is given for the allowed type of instabilities and the time scale of the exponential growth of the instabilities is calculated. The results are compare...

The narrow peak recently found in various pionic double charge exchange (DCX) cross sections can be explained by the assumption of a universal resonance at 2065 MeV, called d ′. We calculate the mass of a six-quark system with J P = 0 − , T = 0 quantum numbers employing a cluster model and a shell model basis to diagonalize the nonrelativistic quark model Hamiltonian.

The effective intercept parameter of the two-pion Bose-Einstein Correlation function, λ * , is found to be sensitive to partial restoration of U A (1) symmetry in ultra-relativistic nuclear collisions. An increase in the yield of the η ′ meson, proposed earlier as a signal of partial U A (1) restoration, is shown to create a " hole " in the low p t region of λ *. A comparison with NA44 data [1]...

Bertsch Dept. of Physics and Institute for Nuclear Theory, FM-15 University of Washington Seattle, WA 98195 Abstract The interferometric analysis of meson correlations provides a measure of the average phase space density of the mesons in the final state. This quantity is a useful indicator of ...

The positivity conditions of the spin density matrix constrain the spin observables of the reaction p̄p → ΛΛ, leading to model-independent, non-trivial inequalities. The formalism is briefly presented and examples of inequalities are provided.
