متن کاملOrigins of single transverse spin asymmetries
Several spin asymmetries in processes involving only one transversely polarized hadron have been observed experimentally; these, when occurring in a kinematical region where pQCD should be applicable, pose a severe challenge to a correct phenomenological description, as single spin asymmetries are negligible in the elementary interactions, due to chirality conservation of QCD and QED dynamics. ...
متن کاملSingle hadron transverse spin asymmetries from COMPASS
Transverse spin physics is an important part of the scientific programme of the COMPASS experiment at CERN. The analysis of the data taken with the target polarized orthogonally to the 160 GeV/c muon beam momentum has allowed to measure for the first time the Collins and Sivers asymmetries of the deuteron. Both for the positive and the negative hadrons produced in semi-inclusive DIS the measure...
متن کاملCOMPASS Results on Transverse Single-Spin Asymmetries
New results on single spin asymmetries of charged hadrons produced in deep-inelastic scattering of muons on a transversely polarised LiD target are presented. The data were taken in the years 2002, 2003 and 2004 with the COMPASS spectrometer using the muon beam of the CERN SPS at 160 GeV/c. Preliminary results are given for the Sivers asymmetry and for all the three “quark polarimeters” present...
متن کاملTransverse single spin asymmetries in photon production
Transverse single-spin asymmetries (SSA) in inclusive reactions are now considered to be directly related to the transverse momentum kT of the fundamental partons involved in the process. We find that the ideal probe to extract information on the gluon Sivers function is the transverse SSA of prompt photon production pp → γX, at large pT . The following related processes, pp → γ + jet + X, pp →...
