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 …

Measurements are presented from proton-proton collisions at centre-of-mass energies of
sqrt (s)= 0.9, 2.36 and 7 TeV recorded with the ATLAS detector at the LHC. Events were …

The pseudorapidity density and multiplicity distribution of charged particles produced in
proton–proton collisions at the LHC, at a centre-of-mass energy s=7 TeV, were measured in …

Charged-particle production was studied in proton–proton collisions collected at the LHC
with the ALICE detector at centre-of-mass energies 0.9 TeV and 2.36 TeV in the …

The inclusive charged particle transverse momentum distribution is measured in proton–
proton collisions at s= 900 GeV at the LHC using the ALICE detector. The measurement is …

The first measurements from proton-proton collisions recorded with the ATLAS detector at
the LHC are presented. Data were collected in December 2009 using a minimum-bias …

We report on the measurement of two-pion correlation functions from pp collisions at s= 900
GeV performed by the ALICE experiment at the Large Hadron Collider. Our analysis shows …

The energy-dependence of charged particle mean multiplicity and pseudorapidity density at
midrapidity measured in nucleus–nucleus and (anti) proton–proton collisions are studied in …

The properties of the quark–gluon medium observed in high-energy nucleus–nucleus
collisions are discussed. The main experimental facts about these collisions are briefly …
