    Dijet production has been measured in pPb collisions at a nucleon–nucleon centre-of-mass energy of TeV. A data sample corresponding to an integrated luminosity of 35 nb[superscript −1] was collected using the Compact Muon Solenoid detector at the Large Hadron Collider. The invariant differential cross sections for inclusive π0 and η mesons at midrapidity were measured in pp collisions at s= TeV for transverse momenta Cited by:

Transverse-momentum and pseudorapidity distributions of charged hadrons in pp collisions at root s= and TeV Article (PDF Available) in Journal of High Energy Physics (02) Charged particles (h±) and K0 mesons have been studied in photoproduced events containing at least one jet of ET > 8 GeV n a pseudorapidity interval (, ) in the ZEUS laboratory frame.

Charged-hadron transverse-momentum and pseudorapidity distributions in proton-proton collisions at p s = 7 TeV are measured with the inner tracking system of the CMS detector at the LHC.

The charged-hadron yield is obtained by count-ing the number of reconstructed hits, hit-pairs, and fully reconstructed charged-particle Size: KB. The measurements presented in this paper are the inclusive primary charged-hadron multiplic-ity densities (dN ch/dp T and dN ch/dh) in the pseudorapidity range jhj.

A study of the charged particles emitted together with a large transverse momentum π O was made at the CERN ISR at a centre-of-mass energy s = π O mesons and the charged particles were observed in two detectors, each centred at θ cm = 90° and each covering a laboratory solid angle of sr for π o 's and sr for charged particles.

• The transverse momentum distribution in the CSS formalism is schematically given by: boson production. We compare the predicted Q T distributions for Higgs boson production at different masses.

The peak of the distribution shifts to greater Q T as m h grows, in approximately linear fashion, and the distribution broadens somewhat. The mean. The transverse momentum distributions and branching ratios of mesons produced together with a lepton pair are studied in pp and p p collisions.

A simple phenomenological formula describing the p T distributions is proposed. The large-p T behaviour of produced mesons can be used to determine the gluon distribution in the proton and to test its Q 2 variation as predicted by : A.

Kotański, J. Kubar. The differential cross sections for inclusive neutral pions as a function of transverse and longitudinal momentum in the very forward-rapidity region have been measured at the LHC with the LHC forward detector in proton-proton collisions at s= and 7 TeV and in proton-lead collisions at nucleon-nucleon center-of-mass energies of sNN= TeV.

We study the transverse momentum distribution of hadrons within jets, where the transverse momentum is defined with respect to the standard jet axis. We consider the case where the jet substructure measurement is performed for an inclusive jet sample pp → jet + X. We demonstrate that this observable provides new opportunities to study transverse momentum Cited by: A complete, fundamental understanding of the proton must include knowledge of the underlying spin structure.
