Description

This paper describes a measurement of the $Z/\gamma^*$ boson transverse momentum spectrum using ATLAS proton-proton collision data at a centre-of-mass energy of $\sqrt{s}$ = 7 TeV at the LHC. The measurement is performed in the $Z/\gamma^* \rightarrow e^+e^-$ and $Z/\gamma^* \rightarrow \mu^+\mu^-$ channels, using data corresponding to an integrated luminosity of 4.7 fb$^{-1}$. Normalized differential cross sections as a function of the $Z/\gamma^*$ boson transverse momentum are measured for transverse momenta up to 800 GeV. The measurement is performed inclusively for $Z/\gamma^*$ rapidities up to 2.4, as well as in three rapidity bins. The channel results are combined, compared to perturbative and resummed QCD calculations and used to constrain the parton shower parameters of Monte Carlo generators.

تصف هذه الورقة قياس طيف الزخم العرضي للبوزون $Z /\gamma ^*$ باستخدام بيانات اصطدام أطلس بالبروتون والبروتون عند طاقة مركز الكتلة $\sqrt{s}$ = 7 TeV في مصادم الهدرونات الكبير. يتم إجراء القياس في قنوات $Z /\ GAMMA ^*\ rightarrow e ^+ e^-$ و $Z /\ GAMMA ^*\rightarrow \mu ^+\mu ^-$، باستخدام بيانات تتوافق مع لمعان متكامل قدره 4.7 fb $^{-1 }$. يتم قياس المقاطع العرضية التفاضلية المعيارية كدالة للزخم العرضي لـ $Z /\gamma ^*$ boson للعزم العرضي حتى 800 GeV. يتم إجراء القياس بشكل شامل لسرعات $Z /\ GAMMA^*$ التي تصل إلى 2.4، وكذلك في ثلاث صناديق للسرعة. يتم الجمع بين نتائج القناة، مقارنة بحسابات دائرة مراقبة الجودة المضطربة والمستأنفة وتستخدم لتقييد معلمات دش بارتون لمولدات مونت كارلو.

Les sections efficaces différentielles normalisées en fonction du moment transversal du boson $Z/\gamma^*$ sont mesurées pour des moments transversaux allant jusqu'à 800 GeV. La mesure est effectuée de manière inclusive pour des vitesses $Z/\gamma^*$ jusqu' à 2,4, ainsi que dans trois bacs de rapidité. Les résultats des canaux sont combinés, comparés aux calculs de QCD perturbateurs et repris et utilisés pour contraindre les paramètres de douche parton des générateurs Monte Carlo.
