Implications of tau data for CP violation in K decays

Multiple interactions, diffraction, and the BFKL pomeron

In high energy pp scattering the inclusive cross section for minijet production is very large. Unitarity then implies a high probability for multiple interactions, and a large diffractive cross section. As the proton has a substructure in terms of parton cascades, the diffraction is not only elastic, but has a large component of diffractive excitation. The cascades can fill the whole rapidity ran

Colour Dipole Cascades

Diffraction, Good-Walker, and the BFKL pomeron

The proton has a substructure in terms of parton cascades, which in a high energy collision fills the whole rapidity range between projectile and target. In the Good–Walker formalism the fluctuations in the cascades will give rise to diffractive excitation. Within the Lund Dipole Cascade model, it is in this way possible to reproduce diffractive excitation in pp collisions and DIS. In central pp c

Event generators for heavy-ion physics, recent developments

A short review is presented for the most commonly used general purpose event generators for heavy ion physics, HIJING, AMPT, and EPOS. A new model, called Angantyr, is presented. It is (similar to HIJING) an extrapolation of pp dynamics to collisions with nuclei. Diffractive excitation of individual nucleons has significant effects in nucleus collisions, and here Angantyr is the first model which

Monte Carlo generators

I discuss some recent development of Monte Carlo event generators and point out some problems. Starting with the issue of combining matrix element generators and parton shower algorithms, I will continue with discussing the problems associated with describing small-x final states and discuss some recent model developments for describing multiple partonic scatterings and underlying events in hadron
