研究成果名稱(英):Observation of sign change in Drell-Yan Sivers function
簡要記述(中):對於質子內部夸克組成的瞭解,已經由一維縱向動量分布,加入了橫向空間或橫向動量的資訊,進入了細緻的多維分布描述。其中,Sivers 函數是描述整體質子橫向自旋,與其內部夸克橫向動量的關連性,它會反映出夸克的橫向軌道運動效果,我們已經在SIDIS過程中發現Sivers 函數的強度是不為零,這也意味著夸克的橫向軌道運動的存在。透過量子色動力學(QCD)對於強作用力的描述,因為強作用力在SIDIS和Drell-Yan這兩個過程的時間方向是相反的,據此做出一個重要的預測:透過這二反應所得到的Sivers 函數的符號將是相反的。為了檢證這個預測,在2015年CERN COMPASS實驗組進行了首次橫向極化Drell-Yan過程的量測,實驗的結果的確與QCD的預測是相符的,為整體質子夸克橫向動量動量分布研究的正確性提供了極重要的實驗證據。
簡要記述(英):Our understanding of the partonic structures of protons has been deepened from the one-dimension longitudinal momentum distributions to multi-dimensional distributions with additional dependency on transverse size or transverse momentum. Among the transverse momentum dependent parton distributions (TMDs), Sivers function describes the correlation between the transverse spin of the parent proton and the transverse momentum of the probed quark. A nonzero Sivers function is considered to be the strong evidence of quark orbital motion. The effects of a nonzero Sivers function have been observed in the semi-inclusive deep inelastic scattering (SIDIS) process. A fundamental prediction based on the factorization of Quantum Chromodynamics (QCD) is a sign change of Sivers functions between SIDIS and Drell-Yan processes due to their opposite time directions of the strong interaction involved. This milestone test has been recently accomplished by the COMPASS collaboration in 2015 transversely-polarized Drell-Yan run. The observed sign of Sivers functions is found to be consistent with the prediction of QCD. This work provides the essential experimental validation of the overall study of TMD partonic structures of protons.
