Název v původním jazyce

Measurement of photon–jet transverse momentum correlations in 5.02 TeV Pb + Pb and pp collisions with ATLAS

Popis výsledku v původním jazyce

Jets created in association with a photon can be used as a calibrated probe to study energy loss in the medium created in nuclear collisions. Measurements of the transverse momentum balance between isolated photons and inclusive jets are presented using integrated luminosities of 0.49 nb −1 of Pb + Pb collision data at sNN=5.02 TeV and 25 pb −1 of pp collision data at s=5.02 TeV recorded with the ATLAS detector at the LHC. Photons with transverse momentum 63.1<pTγ<200 GeV and |ηγ|<2.37 are paired with all jets in the event that have pTjet>31.6 GeV and pseudorapidity |ηjet|<2.8 . The transverse momentum balance given by the jet-to-photon pT ratio, xJγ , is measured for pairs with azimuthal opening angle Δϕ>7π/8 . Distributions of the per-photon jet yield as a function of xJγ , (1/Nγ)(dN/dxJγ) , are corrected for detector effects via a two-dimensional unfolding procedure and reported at the particle level.
