Multi-jet production and transverse momentum dependent parton distributions
We study the impact of transverse-momentum dependent parton distributions on detailed features of multi-jet final states, focusing on angular jet correlations in DIS data. Monte-Carlo simulations of events containing multiple jets are central to a number of processes of interest at LHC energies, see e.g. [1], and further references in [2]. These complex events, characterized by multiple hard sc...
متن کاملNew Showers with Transverse-momentum-ordering
The initial[1, 2, 3] and final-state [4, 5] showers in the PYTHIA event generator [6, 7] are based on virtuality-ordering, i.e. uses spacelike Q2 and timelike M2, respectively, as evolution variables. Other algorithms in common use are the angular-ordered ones in HERWIG [8, 9] and the p?-ordered dipole-based ones in ARIADNE/LDC [10, 11]. All three have been comparably successful, in terms of ab...
متن کاملAngular correlations in multi-jet final states from k⊥-dependent parton showers
We investigate parton-branching methods based on transverse-momentum dependent (TMD) parton distributions and matrix elements for the Monte Carlo simulation of multi-particle final states at high-energy colliders. We observe that recently measured angular correlations in ep final states with multiple hadronic jets probe QCD coherence effects in the space-like branching, associated with finite-a...
متن کاملTransverse-Momentum-Ordered Showers and Interleaved Multiple Interactions
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 initialstate radiation. As a first step we develop new transverse-momentum-ordered showers for initialand final-s...
متن کاملJet physics and initial-state QCD parton showers
We discuss methods of parton branching to treat corrections to QCD showers beyond the collinear ordering approximation in hadronic collisions at high energies. We illustrate the role of finite-angle gluon radiation for angular and momentum correlations in multi-jet final states, and describe applications to forward jets at the LHC.
