    Title: Two particle correlations with photon and pi0 triggers in ALICE at LHC
    Author: Mao, Yaxian
    Subject: High Energy Physics - Experiment ; Nuclear Experiment
    Description: Comparing the measurements of the hadronic final state from partonic showers in proton-proton and heavy-ion collisions will reveal the modifications generated by the medium on partons produced in hard scatterings. This can be achieved by selecting the hard processes in which there is a direct photon in the final state. The experimental technique consists in tagging events with a well identified high energy direct photon and in measuring the azimuthal angle correlation with charged hadrons. To establish a reference measurement for heavy-ion collisions, proton-proton collision data collected with ALICE have been analyzed. Preliminary results are presented together with photon and $\pi^{0}$-charged hadrons correlations showing the characteristic di-jet pattern from where the partonic momentum $k_{T}$ is extracted.

    Title: Gamma-hadrons and hadrons-hadrons correlation measurements in pp collisions at 7TeV to study jet fragmentation with ALICE at LHC
    Author: Mao, Yaxian

    Subject: Physics ; High Energy Physics - Experiment ; Jet Fragmentation ; Photons ; Alice ; Lhc ; Quark-Gluon Plasma ; Heavy-Ions ; Lhc ; Alice ; Photons ; Fragmentation Des Jets ; Quark-Gluon Plasma ; Ions-Lourds ; Physics
    Description: The ALICE experiment, which uses the ultra-relativistic heavy-ions collisions produced by the LHC at CERN, is dedicated to the study of a new state of nuclear matter, which could be composed of a Quark-Gluon Plasma (QGP). Among the probes sharing information on the medium properties, those relative to the production of high transverse momentum jets are very interesting. The analysis presented in this thesis is focused on photon-jet events, which contain one photon of high transverse momentum and one jet emitted in the opposite direction. The jet comes from the fragmentation of the initial parton, after passing through the medium. The thesis includes a simulation study of the relevant observables for the photon-hadron correlation measurement and an analysis of first data from LHC in proton-proton collisions. Preliminary results on the transverse momentum of incident partons and on the correlation function have been obtained. L'expérience ALICE, qui...

    Title: Mesure des corrélations gamma-hadrons et hadrons-hadrons dans les collisions pp à 7 TeV pour l'étude de la fragmentation des jets avec l'expérience ALICE du LHC
    Author: Mao, Yaxian

    Description: L'expérience ALICE, qui utilise les collisions d'ions lourds ultra-relativistes produites par le LHC au CERN, est dédiée à l'étude d'un nouvel état de la matière nucléaire, qui pourrait se présenter sous la forme d'un plasma de quarks et de gluons (QGP). Parmi les sondes portant des informations sur les propriétés de ce milieu, celles relatives à la production des jets de grande impulsion transverse sont particulièrement intéressantes. L'analyse présentée dans cette thèse s'intéresse aux évènements photon-jet, qui comportent un photon de grande impulsion transverse avec un jet émis dans la direction opposée. Ce dernier est issu de la fragmentation d'un parton, une fois qu'il a traversé le QGP. La thèse comprend une étude des observables pertinentes pour la mesure des corrélations photon-hadron ainsi qu'une analyse des premières données du LHC en collisions proton-proton. Des résultats préliminaires sur l'impulsion transverse des partons incidents et la fonction de corrélation...

    Contributor: Furget, Christophe (pacrepositoryorg)
    Subject: Heavy Ions ; Hadrons ; Correlation Analysis ; Ionic Collisions
    Description: \(\gamma +\)jet events provide a tomographic measurement of the medium formed in heavy ion collisions at LHC energies. Tagging events with a well identified high \(p_{T}\) direct photon and measuring the correlation distribution of hadrons emitted oppositely to the photon, allows us to determine, with a good approximation, both the jet fragmentation function and the back-to-back azimuthal misalignement of the direct photon and the jet. Comparing these two observables measured in \(pp\) collisions with the ones measured in \(AA\) collisions will reveal the modifications of the jet structure induced by the medium formed in \(AA\) collisions and consequently will infer the medium properties.

    Title: QGP tomography with photon tagged jets in ALICE
    Author: Mao, Yaxian; Schutz, Yves; Zhou, Daicui; Furget, Christophe; Balbastre, Gustavo Conesa
    Subject: High Energy Physics - Phenomenology
    Description: $\gamma +$jet events provide a tomographic measurement of the medium formed in heavy ion collisions at LHC energies. Tagging events with a well identified high $p_{T}$ direct photon and measuring the correlation distribution of hadrons emitted oppositely to the photon, allows us to determine, with a good approximation, both the jet fragmentation function and the back-to-back azimuthal misalignement of the direct photon and the jet. Comparing these two observables measured in $pp$ collisions with the ones measured in $AA$ collisions will reveal the modifications of the jet structure induced by the medium formed in $AA$ collisions and consequently will infer the medium properties.
