| dc.description.abstract | ENGLISH ABSTRACT: The measurements for the study of heavy-quark production in proton-proton (pp) collisions with ALICE at Large Hadron Collider (LHC) energies are described. Heavy-quarks (charm and beauty) are produced at an early stage of the collision via hard parton scatterings. In ALICE, heavy-quarks are measured in the central barrel (j j < 0:9) via the hadronic and electronic decay channels and at forward rapidity (4 < < 2:5) via the single muon decay channel. These measurements provide a testing ground for quantum chromodynamics (QCD) theoretical models and also serve as a baseline for heavy-ion collisions. This study focuses on the measurement of heavy-quark production via the inclusive single muon decay channel at forward rapidity in the ALICE Muon Spectrometer. In this region, one is able to exploit the single high and low transverse momentum (pT ) triggers to measure the inclusive single muon pT and pseudorapidity ( ) differential cross sections. These single muon differential cross sections are presented and compared to model calculations, by means of the Fixed Order plus Next-to-Leading Logarithms (FONLL). | en_ZA |
| dc.description.abstract | AFRIKAANSE OPSOMMING: Die metings vir die studie van die produksie van swaar kwarke in protonproton (pp) botsings met ALICE by energieë van die Large Hadron Collider (LHC) word beskryf. Swaar kwarke (sjarme en skoonheid) word op ’n vroeë tydstip tydens die botsings d.m.v. harde partonverstrooiing geskep. In ALICE word die swaar kwarke, wat in hadrone en elektrone verval, in die sentrale detektordeel (j j < 0:9) gemeet, terwyl hulle enkel muonverval by voorwaatse pseudorapiditeit (4 < < 2:5) gemeet word. Sulke metings bied o.a. ook ’n toetsgrond vir kwantum-kromodinamika modelle (QCD) en dien ook as ’n riglyn vir botsings van swaar ione. Hierdie studie fokus op die meting van die produksie van swaar kwarke d.m.v. die inklusiewe enkel muon-vervalkanaal by voorwaatse rapiditeit m.b.v. die ALICE Muon-Spektrometer. In hierdie geval kan die snellersein vir enkel muone met hoë en lae transversale momentum (pT ) gebruik word om die inklusiewe enkel muon differensiële kansvlak as funksie van pT en pseudorapiditeit ( ) te meet. Hierdie differensiële kansvlakke word aangebied en vergelyk met modelberekeninge, deur middel van die vaste orde plus naasliggende-leidende logaritmes (FONLL). | af_ZA |
