Download Charged Particle Transverse Momentum Spectra in Pp Collisions at Sqrt(s) Book in PDF, ePub and Kindle
The charged particle transverse momentum (pT) spectra are presented for pp collisions at sqrt(s)=0.9 and 7 TeV. The data samples were collected with the CMS detector at the LHC and correspond to integrated luminosities of 231 inverse microbarns and 2.96 inverse picobarns, respectively. Calorimeter-based high-transverse-energy triggers are employed to enhance the statistical reach of the high-pT measurements. The results are compared with both leading-order QCD and with an empirical scaling of measurements at different collision energies using the scaling variable xT = 2 pT/sqrt(s) over the pT range up to 200 GeV/c. Using a combination of xT scaling and direct interpolation at fixed pT, a reference transverse momentum spectrum at sqrt(s)=2.76 TeV is constructed, which can be used for studying high-pT particle suppression in the dense QCD medium produced in heavy-ion collisions at that centre-of-mass energy.

Download Modification of K0s and Lambda(AntiLambda) Transverse Momentum Spectra in Pb-Pb Collisions at √sNN = 2.76 TeV with ALICE Book in PDF, ePub and Kindle
This thesis offers an excellent, comprehensive introduction to the physics of the quark–gluon plasma. It clearly explains the connection between theory and experiment, making the topic accessible to non-specialists in this field. The experimental work, which contributes significantly to our understanding of the quark–gluon plasma, is described in great detail. The results described in the final chapters of the thesis provide interesting new ideas about the connection between proton-proton and Pb-Pb collisions. Simone Schuchmann received the 'ALICE Thesis Award 2016' for this excellent work.

Download Analysis of the Apparent Nuclear Modification in Peripheral Pb-Pb Collisions at 5.02 TeV Book in PDF, ePub and Kindle
Charged-particle spectra at midrapidity are measured in Pb-Pb collisions at the centre-of-mass energy per nucleon-nucleon pair √sNN = 5.02 TeV and presented in centrality classes ranging from most central (0-5%) to most peripheral (95-100%) collisions. Possible medium effects are quantified using the nuclear modification factor (RAA) by comparing the measured spectra with those from proton-proton collisions, scaled by the number of independent nucleon-nucleon collisions obtained from a Glauber model. At large transverse momenta (8

Download Measurements of Lambda, Lambda-bar and K-short from Pb-Pb Collisions at 158 GeV Per Nucleon in a Large Acceptance Experiment Book in PDF, ePub and Kindle
The main reason for studying relativistic heavy-ion collisions is to discover the phase transition from nuclear matter to the Quark-Gluon Plasma. Such a transition is predicted to occur under conditions of high temperature and density. The predicted state features deconfined quarks and gluons as the relevant degrees of freedom instead of colour-singlet hadrons. These new degrees of freedom should lead to an enhanced production of strange quarks which has directly observable consequences on the composition of the final state hadrons detected in such a collision. The NA49 experiment is able to measure hadronic production in central Pb+Pb collisions. It uses a Pb beam, of energy 158 GeV per nucleon, from the CERN SPS with a fixed Pb target. The experiment features four large tracking detectors which can measure the trajectories of charged particles. In this thesis the method of reconstructing neutral strange particles, Lambda, Lambda-bar and K-short from their charged decay products is described. The procedure for correcting the raw yields for losses due to the limited experimental acceptance and efficiency in reconstruction is explained. An estimate of some systematic errors is made. The resulting rapidity distributions, which span either side of mid-rapidity are peaked (with the possible exception of Lambda) and the transverse momentum spectra fit the Hagedorn distribution. The inverse slope parameters, T_Lambda = 274? 5 MeV, T_Lambda-bar = 279? 10 MeV and T_K = 238? 5 MeV are consistent with the picture of transverse flow observed in these collisions. These results are compared with other measurements.
