After an introduction motivating the study of quarkonium production, we review the recent
developments in the phenomenology of quarkonium production in inclusive scatterings of …

In this report we review recent developments in perturbation-theory methods for gauge
theories. We present techniques and results that are useful in the calculation of cross …

Using proton-proton collision data at centre-of-mass energies of s= 7, 8 and 13 TeV
recorded by the LHCb experiment at the Large Hadron Collider, corresponding to an …

New sets of parameters (“tunes”) for the underlying-event (UE) modelling of the pythia 8,
pythia6 and herwig++ Monte Carlo event generators are constructed using different parton …

We present 9 new tunes of the p⊥-ordered shower and underlying-event model in Pythia
6.4. These “Perugia” tunes update and supersede the older “S0” family. The data sets used …

The Pythia program can be used to generate high-energy-physicsevents', ie sets of outgoing
particles produced in the interactions between two incoming particles. The objective is to …

A detailed model for hadronic events is presented, with particular emphasis put on the event
structure at low transverse momenta, ie,''beam jets''and ''minijets.''Specifically, we argue that …

A bstract We review the modelling of multiple interactions in the event generator H erwig++
and study implications of recent tuning efforts to Tevatron and LHC data. It is often said that …

Pythia version 6 represents a merger of the Pythia 5, Jetset 7 and SPythia programs, with
many improvements. It can be used to generate high-energy-physics 'events', ie sets of …

A bstract We discuss extensions of multi-jet matrix element and parton shower merging
approaches, to also include next-to-leading order accuracy. Specifically, we generalise the …
