Abstract The multiplicity dependence of jet production in pp collisions at the centreofmass 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 $$\eta _{\mathrm{jet}}< 0.9R$$  η jet  < 0.9  R and in the transverse momentum range $$5more »
Single inclusive jet production in pA collisions at NLO in the smallx regime
A bstract We present the first complete nexttoleadingorder (NLO) prediction with full jet algorithm implementation for the single inclusive jet production in pA collisions at forward rapidities within the color glass condensate (CGC) effective theory. Our prediction is fully differential over the final state physical kinematics, which allows the implementation of any infrared safe observable including the jet clustering procedure. The NLO calculation is organized with the aid of the observable originated power counting proposed in [1] which gives rise to the novel soft contributions in the CGC factorization. We achieve the fullydifferential calculation by constructing suitable subtraction terms to handle the singularities in the real corrections. The subtraction contributions can be exactly integrated analytically. We present the NLO cross section with the jets constructed using the anti k T algorithm. The NLO calculation demonstrates explicitly the validity of the CGC factorization in jet production. Furthermore, as a byproduct of the subtraction method, we also derive the fully analytic cross section for the forward jet production in the small R limit. We show that in the small R approximation, the forward jet cross section can be factorized into a semihard cross section that produces a parton and the semiinclusive jet more »

A bstract A measurement of the inclusive bjet production cross section is presented in pp and pPb 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. The p T differential inclusive production cross section of b jets, as well as the corresponding inclusive bjet fraction, are reported for pp and pPb collisions in the jet transverse momentum range 10 ≤ p T , ch jet ≤ 100 GeV/ c , together with the nuclear modification factor, $$ {R}_{\mathrm{pPb}}^{\mathrm{b}\mathrm{jet}} $$ R pPb b − jet . The analysis thus extends the lower p T limit of bjet measurements at the LHC. The nuclear modification factor is found to be consistent with unity, indicating that the production of b jets in pPb at $$ \sqrt{s_{\mathrm{NN}}} $$ s NN = 5 . 02 TeV is not affected bymore »

Abstract This article presents new measurements of the fragmentation properties of jets in both proton–proton (pp) and heavyion collisions with the ALICE experiment at the Large Hadron Collider (LHC). We report distributions of the fraction z r of transverse momentum carried by subjets of radius r within jets of radius R . Chargedparticle jets are reconstructed at midrapidity using the anti k T algorithm with jet radius R = 0 . 4, and subjets are reconstructed by reclustering the jet constituents using the anti k T algorithm with radii r = 0 . 1 and r = 0 . 2. In proton–proton collisions, we measure both the inclusive and leading subjet distributions. We compare these measurements to perturbative calculations at nexttoleading logarithmic accuracy, which suggest a large impact of threshold resummation and hadronization effects on the z r distribution. In heavyion collisions, we measure the leading subjet distributions, which allow access to a region of harder jet frag mentation than has been probed by previous measurements of jet quenching via hadron fragmentation distributions. The z r distributions enable extraction of the partontosubjet fragmentation function and allow for tests of the universality of jet fragmentation functions in the quark–gluon plasma (QGP).more »

A bstract We derive the transverse momentum dependent (TMD) factorization and resummation formula of the unpolarized transverse momentum distribution ( j T ) for the single hadron production with the thrust axis in an electronpositron collision. Two different kinematic regions are considered, including small transverse momentum limit j T « Q , and joint transverse momentum and threshold limit j T « Q (1 − z h ) « Q , where Q and z h are the hard scattering energy and the observed hadron momentum fraction. Using effective theory methods, we resum logarithms ln( Q/j T ) and ln(1 − z h ) to all orders. In the end, we present the differential cross sections and Gaussian widths calculated for the inclusive charged pion production and find that our results are consistent with the measurements reported by the Belle collaboration.

Abstract The invariant differential cross section of inclusive $$\omega (782)$$ ω ( 782 ) meson production at midrapidity ( $$y<0.5$$  y  < 0.5 ) in pp collisions at $$\sqrt{s}=7\,\hbox {TeV}$$ s = 7 TeV was measured with the ALICE detector at the LHC over a transverse momentum range of $$2< p_{\mathrm {T}}< 17\,\hbox {GeV}/c$$ 2 < p T < 17 GeV / c . The $$\omega $$ ω meson was reconstructed via its $$\omega \rightarrow \pi ^+\pi ^\pi ^0$$ ω → π + π  π 0 decay channel. The measured $$\omega $$ ω production cross section is compared to various calculations: PYTHIA 8.2 Monash 2013 describes the data, while PYTHIA 8.2 Tune 4C overestimates the data by about 50%. A recent NLO calculation, which includes a model describing the fragmentation of the whole vectormeson nonet, describes the data within uncertainties below $$6\,\hbox {GeV}/c$$ 6 GeV / c , while it overestimates the data by up to 50% for higher $$p_{\mathrm {T}}$$ p T . The $$\omega /\pi ^0$$ ω / π 0 ratio is in agreement with previous measurements at lower collision energies and the PYTHIA calculations. In addition, the measurement is compatible with transverse mass scaling within the measured $$p_{\mathrm {T}}$$more »
