Single spin asymmetries in hadron-hadron collisions
We study weighted azimuthal single spin asymmetries in hadron-hadron scattering using the diagrammatic approach at leading order and assuming factorization. The effects of the intrinsic transverse momenta of the partons are taken into account. We show that the way in which T -odd functions, such as the Sivers function, appear in these processes does not merely involve a sign flip when compared ...
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 کاملSingle transverse spin asymmetries in inclusive hadron production
A consistent phenomenological approach to the computation of transverse single spin asymmetries in inclusive hadron production is presented, based on the assumed generalization of the QCD factorization theorem to the case in which quark intrinsic motion is taken into account. New k⊥ and spin dependent quark distribution and fragmentation functions are considered: some of them are fixed by fitti...
متن کاملAn approximation for NLO single Higgs boson inclusive transverse momentum distributions in hadron-hadron collisions
In the framework of the gluon-gluon fusion process for Higgs boson production there are two different prescriptions. They are given by the exact process where the gluons couple via top-quark loops to the Higgs boson and by the approximation where the top-quark mass mt is taken to infinity. In the latter case the coupling of the gluons to the Higgs boson is described by an effective Lagrangian. ...
متن کاملSpin Polarization of Hyperons in the Hadron-hadron Inclusive Collisions
The high energy hadron-hadron collisions produce various hyperons, in which large spin polarizations perpendicular to a production plane are observed at high Feynman-x (xF ) and low transverse momentum pT . For these collisions, we have proposed a global model on the basis of quark rearrangements concept. In order to produce a final state hyperon at high xF , we consider possible rearrangement ...
