Transverse-momentum-ordered showers and interleaved multiple interactions

Sjöstrand, Torbjörn LU orcid and Skands, Peter LU (2005) In European Physical Journal C. Particles and Fields 39(2). p.129-154
Abstract
We propose a sophisticated framework for high-energy hadronic collisions, wherein different QCD physics processes are interleaved in a common sequence of falling transverse-momentum values. Thereby phase-space competition is introduced between multiple parton-parton interactions and initial-state radiation. As a first step we develop new transverse-momentum-ordered showers for initial- and final-state radiation, which should be of use also beyond the scope of the current article. These showers are then applied in the context of multiple interactions, and a few tests of the new model are presented. The article concludes with an outlook on further aspects, such as the possibility of a shower branching giving partons participating in two... (More)
