Heavy Baryon Transitions in a Relativistic Three-Quark Model

M. A. Ivanov, J. G. Korner, P. Kroll +1

Exclusive semileptonic decays of bottom and charm baryons are considered within a relativistic three-quark model with a Gaussian shape for the baryon-three-quark vertex and standar…

Small-Angle Excess Scattering: Glassy Freezing or Local Orientational Ordering?

H. Weber, W. Paul, W. Kob +1

We present Monte Carlo simulations of a dense polymer melt which shows glass-transition-like slowing-down upon cooling, as well as a build up of nematic order. At small wave vector…

A dispersion theoretical approach to the threshold amplitudes of pion photoproduction

O. Hanstein, D. Drechsel, L. Tiator

We give predictions for the partial wave amplitudes of pion photoproduction near threshold by means of dispersion relations at fixed t. The free parameters of this approach are det…

Orthorhombic Phase of Crystalline Polyethylene: A Monte Carlo Study

R. Martonak, W. Paul, K. Binder

In this paper we present a classical Monte Carlo simulation of the orthorhombic phase of crystalline polyethylene, using an explicit atom force field with unconstrained bond length…

Three-Dimensional 3-State Potts Model Revisited With New Techniques

Wolfhard Janke, Ramon Villanova

We report a fairly detailed finite-size scaling analysis of the first-order phase transition in the three-dimensional 3-state Potts model on cubic lattices with emphasis on recentl…

Chiral dynamics of rare eta decays and virtual Compton scattering off the nucleon

S. Scherer

Two different topics relevant for DANE and CEBAF, respectively, are covered. First we analyze the rare radiative eta decay mode within the framework of chiral perturb…
