The p T -differential production cross section of electrons from semileptonic decays of heavy-flavor hadrons has been measured at midrapidity in proton-proton collisions at ffiffi ffi s p ¼ 2.76 TeV in the transverse momentum range 0.5 < p T < 12 GeV=c with the ALICE detector at the LHC. The analysis was performed using minimum bias events and events triggered by the electromagnetic calorimeter. Predictions from perturbative QCD calculations agree with the data within the theoretical and experimental uncertainties.

“…The partonic cross section dσ ij→Q(Q){k} is calculated as a perturbative series in the strong coupling α s , which depends on the energy scale of the process, indicated here as renormalization scale, µ R ; currently, calculations are performed up to next-to-leading order (NLO), O(α 3 s ) (MNR [28], GM-VFNS [29][30][31], MC@NLO [32,33]), or at fixed order with next-to-leading-log resummation (FONLL [34][35][36]). The Parton Distribution Function (PDF), f i (x 1 , µ 2 F ) encodes the partonic structure of the colliding protons and can be interpreted as the probability to find a parton i inside the proton with fraction of momentum x 1 = p i /p p (Bjorken x).…”

This thesis presents the measurement of the charmed D 0 meson production relative to the reaction plane in Pb-Pb collisions at the centre-of-mass energy per nucleon-nucleon collision of √ s NN = 2.76 TeV, and the measurement of the D 0 production in p-Pb collisions at √ s NN = 5.02 TeV with the ALICE detector at the CERN Large Hadron Collider.The D 0 azimuthal anisotropy with respect to the reaction plane is sensitive to the interaction of the charm quarks with the high-density strongly-interacting medium formed in ultra-relativistic heavy-ion collisions and, thus, to the properties of this state of matter. In particular, this observable allows to establish whether low-momentum charm quarks participate in the collective expansion of the system and whether they can reach thermal equilibrium with the medium constituents. The azimuthal anisotropy is quan- −0.036 in the interval 2 < p T < 6 GeV/c, which decreases towards more central collisions. Consequently, the nuclear modification factor shows a stronger suppression in the direction orthogonal to the reaction plane. The v 2 and the R AA measured in two azimuthal regions with respect to the reaction plane are compared to theoretical calculations of charm quark transport and energy loss in high-density strongly-interacting matter. The models that include substantial elastic interactions with an expanding medium provide a good description of the observed anisotropy.The D 0 nuclear modification factor R pPb in p-Pb collisions is compatible with unity within uncertainties. The measured R pPb is compared to theoretical models including initial state effects, as well as to the nuclear modification factor measured in central RiassuntoLa tesi presenta la misura della produzione di mesoni D 0 rispetto al piano di reazione in collisioni Pb-Pb all'energia nel centro di massa di √ s NN = 2.76 TeV per coppia di nucleoni e la misura della produzione di D 0 in collisioni p-Pb all'energia di √ s NN = 5.02 TeV con l'esperimento ALICE situato al Large Hadron Collider del CERN.L'anisotropia azimutale dei mesoni D 0 rispetto al piano di reazioneè sensibile alle interazioni del quark charm con il mezzo ad alta densità e fortemente interagente prodotto in collisioni tra ioni pesanti ad energia ultra-relativistica e, di conseguenza, alle proprietà di questo stato della materia. In particolare, permette di stabilire se i quark charm partecipano all'espansione collettiva del sistema e se raggiungono l'equilibrio termico con i costituenti del mezzo. L'anisotropia azimutaleè quantificata tramite il secondo coefficiente v 2 dello sviluppo in serie di Fourier della distribuzione azimutale dei mesoni D 0 e tramite la misura del fattore di modifica nucleare R AA nel piano di reazione e nella direzione ortogonale ad esso. La misura della produzione di D 0 in collisioni p-Pb permette di studiare gli effetti indotti dalla materia nucleare fredda, in modo da poterli distinguere da quelli indotti dal mezzo denso fortemente interagente prodotto in collisioni Pb-Pb.La produzione di mesoni D 0...
