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

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 …

The study of low energy weak interactions of light quarks and leptons continues to provide
important insights into both the Standard Model as well as the physics that may lie beyond it …

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 …

An up-to-date global QCD analysis of high energy lepton-hadron and hadron-hadron
interactions is performed to better determine the gluon and quark parton distributions in the …

The production of W bosons in association with two jets in proton–proton collisions at a
centre-of-mass energy of√ s= 7 has been analysed for the presence of double-parton …

Increasingly, with the data collected at the LHC we are confronted with the possible
existence of flow in pp collisions. In this work, we show that pythia 8 produces flowlike effects …

A bstract We perform a detailed investigation of multiple hard interactions in hadron-hadron
collisions. We discuss the space-time, spin and color structure of multiple interactions …

A strong signal for double parton (DP) scattering is observed in a 16 pb− 1 sample of pp→
γ/π 0+ 3 jets+ X data from the CDF experiment at the Fermilab Tevatron. In DP events, two …
