چکیده
The production of $\Lambda$ baryons and ${\rm K}^{0}_{\rm S}$ mesons (${\rm V}^{0}$ particles) was measured in p-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV pp $\sqrt{s} 7$ with ALICE the LHC. these strange particles is studied separately for associated hard scatterings underlying event to shed light on baryon-to-meson ratio enhancement observed intermediate transverse momentum ($p_{\rm T}$) high multiplicity collisions. Hard are selected an event-by-event basis jets reconstructed anti-$k_{\rm T}$ algorithm using charged particles. $p_{\rm T,\;jet}^{\rm ch}>10$ ch}>20$ GeV/$c$ collisions, jet reported as a function T}$. Its dependence angular distance from axis, $R({\rm V}^{0},\;{\rm jet})$, well. T}$-differential spectra found be harder compared that both differ inclusive measurements. In events containing jet, density larger than minimum bias events. $\Lambda/{\rm consistent follows expectation fragmenting vacuum. On other hand, this within consistently lower one obtained it does not show characteristic often referred "baryon anomaly"

Production of jets at forward rapidities in hadronic collisions
Experiments at the Large Hadron Collider (LHC) will explore the region of large rapidities both with general-purpose detectors and with dedicated instrumentation, including forward calorimeters and proton taggers [1, 2, 3, 4, 5, 6, 7]. The LHC forward-physics program involves a wide range of topics, from new particle discovery processes [3, 8, 9] to new aspects of strong interaction physics [7,...

متن کاملDiffractive jets production in pp-collisions
We consider the exclusive diffractive dissociation of a proton into three jets with large transverse momenta in the double-logarithmic approximation of perturbative QCD. This process is sensitive to the proton unintegrated gluon distribution at small x and to the proton light-cone distribution amplitudes. According to our estimates, an observation of such processes in the early runs at LHC is f...
