Diffractive Mechanism in Multi-Particle Production Processes

Particle Production Ratios in the Diffractive Excitation Model

Ratios of the invariant distributions of produced particles, R@+/a), R&n) > R(K-/n) , and R(K’/p), have been calculated in the diffractive excitation model. Two free parameters are used to adjust the relative normalization. The shapes of the ratios as functions of x are essentially independent of any arbitrary parameters. The results agree with the data very well. (Submitted to Physics Letters)...

Multi-particle processes with reinforcements

The multi-particle generalization of the edge-reinforced random walk is stated. Some recurrence results are obtained.

- Production in Diffractive DIS

We calculate the cross section for q ¯ qg-production in diffractive DIS with finite fermion masses and zero momentum transfer. The calculation is done in the leading log(1/x P) approximation and is valid for the region of high diffractive masses (small β). We apply our cross section formula to diffractive charm production at HERA: in a Monte-Carlo-Simulation of diffractive D * ± meson productio...

Azimuthal Dependence in Diffractive Processes

Azimuthal distributions in high-energy processes give information about the helicity structure of diffractive reactions. I discuss predictions of several dynamical mechanisms in this context, both for electron-proton and for hadron-hadron collisions. 1 Azimuthal distributions in ep diffraction In this talk I give several examples of what azimuthal distributions can tell us about diffractive int...
