Missing Transverse Momentum

We present the MadAnalysis 5 implementation of the heavily charged gauge boson search to recast the analysis of its decay into one charged lepton and missing transverse momentum. Signal events describing [Formula: see text] ([Formula: see text] or [Formula: see text]) at [Formula: see text] TeV in the sequential standard model are generated by the MadGraph5_aMC@NLO at leading order. The corresponding signal cross-sections for both electron and muon channels vary from 195 fb to 0.238 fb depending on the pole mass of the [Formula: see text] boson in the range of 2 TeV to 6 TeV. We validate our implementation by comparing the transverse mass distributions of our signal prediction to those of the ATLAS analysis for an integrated luminosity of 139 fb[Formula: see text].

The transverse momentum pT spectra of both hadrons and jets produced in pp collisions at beam energies from hundreds GeV to a few TeV exhibit power-law behavior of 1/pTn at high pT, with similar power indices n. The respective nonextensivity parameters for transverse momenta distributions and the global nonextensivity parameter obtained from multiplicities are compared. In particular, data on kaon to pion (charged particles) multiplicity ratio are analyzed, assuming that the reaction occurs in some nonextensive environment. The values of the corresponding nonextensivity parameters were found to be similar, strongly indicating the existence of a common mechanism behind all these observables.

Simulation Results

Effect of the jet production on the multiplicity distribution (MD) of secondary charged particles produced in pp-collisions at 1.8 TeV is studied using the HIJING code. The charged particles MDs for a whole polar angle range and for six polar angular regions as a function of different number of jets were analyzed. The obtained simulation results were compared with experimental MDs coming from the Tevatron and SPS experiments. The increasing behavior of multiplicity of the secondary charged particles influenced by multi-jet events is discussed.

AbstractThe NA61/SHINE experiment at the CERN Super Proton Synchrotron (SPS) studies the onset of deconfinement in hadron matter by a scan of particle production in collisions of nuclei with various sizes at a set of energies covering the SPS energy range. This paper presents results on inclusive double-differential spectra, transverse momentum and rapidity distributions and mean multiplicities of $$\pi ^\pm $$ π ± , $$K^\pm $$ K ± , p and $$\bar{p}$$ p ¯ produced in the 20% most central$$^7$$ 7 Be+$$^9$$ 9 Be collisions at beam momenta of 19A, 30A, 40A, 75A and 150A $${\mathrm{Ge} \mathrm{V}}\!/\!c$$ Ge V / c . The energy dependence of the $$K^\pm $$ K ± /$$\pi ^\pm $$ π ± ratios as well as of inverse slope parameters of the $$K^\pm $$ K ± transverse mass distributions are close to those found in inelastic p+p reactions. The new results are compared to the world data on p+p and Pb+Pb collisions as well as to predictions of the Epos, Urqmd, Ampt, Phsd and Smash models.

In this article, recent ALICE measurements of the RAA and v2 of electrons at mid-rapidity (|y|<0.6) and muons at forward rapidity (2.5<y<4), from semi-leptonic decays of heavy-flavour hadrons in Pb–Pb collisions at [see formula in PDF] = 5.02 TeV are shown. The results of D-tagged jet production cross-section in pp collisions at √s =7 TeV are presented. In addition, the azimuthal correlation of D mesons with charged particles in p–Pb collisions at [see formula in PDF] = 5.02 TeV, and electrons from semi-leptonic decays of heavyflavour hadrons with charged particles in p–Pb and Pb–Pb collisions at [see formula in PDF] = 5.02 TeV are reported.
