Colour dipoles and rho, phi electroproduction
J. R. Forshaw, R. Sandapen, G. Shaw
We present a detailed comparison of a variety of predictions for diffractive light vector meson production with the data collected at the HERA collider. All our calculations are pe…
Logarithmic lift of the su(2)_{-1/2} model
F. Lesage, P. Mathieu, J. Rasmussen +1
This paper carries on the investigation of the non-unitary su(2)_{-1/2} WZW model. An essential tool in our first work on this topic was a free-field representation, based on a c=-…
Monte Carlo Hamiltonian: Inverse Potential
Xiang-Qian Luo, Xiao-Ni Cheng, Helmut Kroger
The Monte Carlo Hamiltonian method developed recently allows to investigate ground state and low-lying excited states of a quantum system, using Monte Carlo algorithm with importan…
Explicit formulas for the generalized Hermite polynomials in superspace
Patrick Desrosiers, Luc Lapointe, Pierre Mathieu
We provide explicit formulas for the orthogonal eigenfunctions of the supersymmetric extension of the rational Calogero-Moser-Sutherland model with harmonic confinement, i.e., the…
Cosmological dynamics of scalar field with non-minimal kinetic term
H. Kröger, G. Melkonyan, S. G. Rubin
We investigate dynamics of scalar field with non-minimal kinetic term. Nontrivial behavior of the field in the vicinity of singular points of kinetic term is observed. In particula…
Quantum chaos and regularity in theory
Helmut Kroeger, Xiang-Qian Luo, Harald Markum +1
We check the eigenvalue spectrum of the Hamiltonian against Poisson or Wigner behavior predicted from random matrix theory. We discuss random matrix theory as a tool…
