摘要: We propose a sophisticated framework for high-energy hadronic collisions, wherein different QCD physics processes are interleaved in common sequence of falling transverse-momentum values. Thereby phase-space competition is introduced between multiple parton-parton interactions and initial-state radiation. As first step we develop new transverse-momentum-ordered showers initial- final-state radiation, which should be use also beyond the scope current article. These then applied context interactions, few tests model presented. The article concludes with an outlook on further aspects, such as possibility shower branching giving partons participating two interactions.
