Measurement of charged particle multiplicities and densities in pp collisions at 7 TeV in the forward region Paul

Measurement of charged-particle multiplicities in gluon and quark jets in p(p)over-bar collisions at root s=1.8 TeV

LHCb Results on Multi-parton Interactions, Soft QCD and Diffraction

Due to its unique pseudorapidity coverage (2 < η < 5) and excellent performance, the LHCb detector allows for studying soft QCD processes at large rapidities and low transverse momenta. Selected results, such as charged particle multiplicities and densities, forward energy flow and prompt charm production are briefly summarized in these proceedings. The measurements are performed using large sa...

Charged pions multiplicities at the NA 49 energy

The wounded quark-diquark model predictions for charged pions multiplicities in P bP b and pP b collisions in the central rapidity region at √ s = 17.3 GeV c.m. energy are presented. 1. The NA49 collaboration published precise results 1 on inclusive production of charged pions in pp collisions at √ s = 17.3 GeV [1]. This measurement allows to investigate the consequences of the wounded quark-di...

Jet structure in pp and Pb-Pb collisions with the ALICE experiment

We report results from the ALICE collaboration on jet production and jet properties in pp and Pb-Pb collisions at the LHC. The charged particle jet production cross-section and measurements of jet fragmentation and jet shape in pp collisions at √ s = 7 TeV are presented. The results are confronted with simulations from Monte Carlo event generators. Measurements of charged particle jets in Pb-Pb...

Evidence for collectivity in pp collisions at the LHC

Measurements of twoand multi-particle angular correlations in pp collisions at √ s = 5, 7, and 13 TeV are presented as a function of charged-particle multiplicity. The data, corresponding to integrated luminosities of 1.0 pb−1 (5 TeV), 6.2 pb−1 (7 TeV), and 0.7 pb−1 (13 TeV), were collected using the CMS detector at the LHC. The second-order (v2) and third-order (v3) azimuthal anisotropy harmon...
