摘要(中) 位於歐洲核子研究中心的COMPASS實驗組, 在2015年 與2018年利用190十億電子伏特的π介子束碰撞三種物質極化 鞍靶,鋁靶,以及鎢靶, 進行Drell-Yan過程的碰撞截面積量測. 選取不變質量為4.3GV-8.5GeV的雙渺子事件,本論文報告多維度的Drell-Yan碰撞截面積的分析方法和結果,事件分佈在費米變量從-0.1到0.9以及橫向動量0.0到3.6 GeV/c範圍 此量測結果將有助於決定π介子的部分子動量分布 COMPASS的 實驗量測反應截面和量子色動力學的理論計算有很好的吻合度在橫向動量平均分布方面的量測,COMPASS的實驗組的量測結果也與過去的實驗量測結果有一致性,可以用於決定π介子的內部節構ž.
摘要(英) The COMPASS experiment at CERN performed measurements
of Drell-Yan process using a 190-GeV negative pion beam
scattering off a NH3 target and nuclear alumina and tungsten targets in 2015 and 2018. We present the results of differential cross sections of the dimuon events with the invariant mass between 4.5 and 8.5 GeV in the kinematic regions of x-Feynman from -0.1 to 0.9 and transverse momentum up to 3.6 GeV/c. Our results are valuable input for constraining the parton distribution functions (PDFs) of the pion. The measured differential cross sections are compared with the next-to-leading
order QCD calculations with pion PDFs provided by JAM and
xFitter groups and a reasonable agreement is observed. The result of the mean square of the transverse momentum versus the center-of-mass energy from COMPASS agrees with the measurements of the other pion-induced Drell-Yan experiments and constrains the intrinsic transverse momentum of pions.
