![]() ![]() Contributions to the process from both the nonhadronic anomaly and the vector-dominance piece are estimated: we find that the cross section from the anomaly dominates the vector-dominance contribution at large Q 2. We investigate the Drell- Yan reaction γp → (μ + μ - ) X with an eye to experimental determination of the photon structure functions. ![]() International Nuclear Information System (INIS) Photoproduction of Drell- Yan lepton pairs The experimental set-up, the status of the data taking in 2015 and preliminary analysis results in the 2. The role of the Drell- Yan experiment at COMPASS in TMD PDFs study, with a comparison to semi-inclusive deep inelastic scattering experiment, is described. After a plot run in 2014, the experiment has just started in 2015. The transversely polarized target together with negative pion beam is an important feature of the COMPASS Drell- Yan experiment, that provides us with unique data on transverse momentum dependent (TMD) PDFs. ![]() Study of angular dependencies of the Drell- Yan process cross-section allows us to access to parton distribution functions (PDFs) or, more precisely, a convolutions of various PDFs. The availability of pion beam provides an access to the Drell- Yan physics throughout the process where quark(target)-antiquark(beam) pair annihilates electromagnetically with a production of dilepton pair. The COMPASS II started at 2012 that includes polarized Drell- Yan program with a polarized solid target. This complicates our understanding of any lag between insolation forcing and monsoon response. East Asian monsoon grainâ€size and magnetic susceptibility records also show several differences between independently dated loess sites. in many other OSLâ€dated Loess Plateau sites. The last glacial maximum peak MAR (22–27 ka) matches the Pacific and Greenland dust flux records, although appears earlier than peak MARs seen. MARs from undisturbed portions of Xifeng vary dramatically, with peaks potentially matching the timing of Heinrich events.
