Multiplicity dependence of charged-particle jet production in pp collisions at $$\mathbf {\sqrt{s}}=\mathbf {13~TeV}$$
Abstract The multiplicity dependence of jet production in pp collisions at the centre-of-mass energy of $$\sqrt{s} = 13\ {\mathrm {TeV}}$$ s = 13 TeV is studied for the first time. Jets are reconstructed from charged particles using the anti- $$k_\mathrm {T}$$ k T algorithm with resolution parameters R varying from 0.2 to 0.7. The jets are measured in the pseudorapidity range $$|\eta _{\mathrm{jet}}|< 0.9-R$$ | η jet | < 0.9 - R and in the transverse momentum range $$5more » Authors: ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; more » Award ID(s): Publication Date: NSF-PAR ID: 10339010 Journal Name: The European Physical Journal C Volume: 82 Issue: 6 ISSN: 1434-6052 Sponsoring Org: National Science Foundation ##### More Like this 1. A bstract A measurement of the inclusive b-jet production cross section is presented in pp and p-Pb collisions at$$ \sqrt{s_{\mathrm{NN}}} $$s NN = 5 . 02 TeV, using data collected with the ALICE detector at the LHC. The jets were reconstructed in the central rapidity region |η| < 0 . 5 from charged particles using the anti- k T algorithm with resolution parameter R = 0 . 4. Identification of b jets exploits the long lifetime of b hadrons, using the properties of secondary vertices and impact parameter distributions.

Abstract Angular correlations of heavy-flavour and charged particles in high-energy proton–proton collisions are sensitive to the production mechanisms of heavy quarks and to their fragmentation as well as hadronisation processes. The measurement of the azimuthal-correlation function of prompt D mesons with charged particles in proton–proton collisions at a centre-of-mass energy of$$\sqrt{s} = 13$$s = 13 TeV with the ALICE detector is reported, considering$$\mathrm D^{0} $$D 0 ,$$\mathrm D^{+} $$D + , and$$\mathrm D^{*+} $$D ∗ + mesons in the transverse-momentum interval$$3< p_{\mathrm{T}} < 36$$3 < p T < 36 GeV/more » 4. Abstract We report on the inclusive$$\text {J}/\psi $$J / ψ production cross section measured at the CERN Large Hadron Collider in proton–proton collisions at a center-of-mass energy$$\sqrt{s}~=~13$$s = 13 TeV. The$$\text {J}/\psi $$J / ψ mesons are reconstructed in the$$\text {e}^{+}\text {e}^{-}$$e + e - decay channel and the measurements are performed at midrapidity ($$|y|<0.9$$| y | < 0.9 ) in the transverse-momentum interval$$0more »
5. Abstract This paper presents the measurements of $$\pi ^{\pm }$$ π ± , $$\mathrm {K}^{\pm }$$ K ± , $$\text {p}$$ p and $$\overline{\mathrm{p}}$$ p ¯ transverse momentum ( $$p_{\text {T}}$$ p T ) spectra as a function of charged-particle multiplicity density in proton–proton (pp) collisions at $$\sqrt{s}\ =\ 13\ \text {TeV}$$ s = 13 TeV with the ALICE detector at the LHC. Such study allows us to isolate the center-of-mass energy dependence of light-flavour particle production. The measurements reported here cover a $$p_{\text {T}}$$ p T range from 0.1 to 20 $$\text {GeV}/c$$ GeV / c and aremore »
