Recent work suggests a close relation between generalized and transverse momentum dependent parton distributions (TMDs), in particular for the so-called naive time-reversal odd TMDs. In the talk our present knowledge on this topic will be briefly summarized. Moreover, an extension of the existing work in the literature will be discussed.

In semi-inclusive DIS of polarized leptons on a transversely polarized target eight azimuthal modulations appear in the cross-section. Within QCD parton model four azimuthal asymmetries can be interpreted at leading order, two of them being the already measured Collins and Sivers asymmetries. The other two leading twist asymmetries, related to different transverse momentum dependent quark dis ... More

Single transverse spin asymmetries (SSA) in transversely polarised pp reactions at the energy regime where pQCD is applicable are expected to be negligibly small in the lowest-oredr QCD approximation, whereas experimentally large SSAs have been observed at high xF. Recently, new measurements of SSAs have been available from semi-inclusive deep-inelastic scattering and transversely polarised pp at ... More

I would like to bring your attention on the Hall A exprimental program about GPDs at JLab.

They involve the HRS spectrometer for the detection of the scattered electron and a new PbF2 calorimeter for the detection of the emitted photon. The latter was specially designed to su ... More

HERMES has used a high statistics data sample of charged inclusive hadrons to measure double spin asymmetries as a function of p_T. From these asymmetries Delta g/g has been extracted in the region of 1<p_T<2 GeV, corresponding to x\approx0.2-0.3 The information on the background asymmetry and the subprocess kinematics has been obtained from a Leading Order Monte Carlo model and existing pa ...

One of the main goals of the COMPASS experiment at CERN is the determination of the gluon polarisation in the nucleon, Delta G/G. It is determined from spin asymmetries measured in the scattering of 160GeV/c polarised muons on a polarised LiD target. The gluon is accessed by the selection of photon-gluon fusion events. A selection of PGF events can be obtained with charmed mesons in the fin ... More

We consider dihadron fragmentation functions, that describe the fragmentation of a parton in two (unpolarized) hadrons. Using Jet calculus techniques, we develop evolution equations when these functions are explicitly depending upon the invariant mass of the produced hadron pair, the socalled extended dihadron fragmentation functions. We connect our results to the integrated dihadron fragment ... More

This proof had been missed in the previous literature. As an application, we ... More

Hard exclusive processes provide access to the unknown generalized parton distributions (GPDs), which extend our description of the nucleon structure beyond the standard parton distributions. The Deeply Virtual Compton Scattering (DVCS) process, i.e. the hard exclusive leptoproduction of real photons, provides the theoretically cleanest access to the GPDs. DVCS amplitudes can be measured most read ... More

In 2005 the HERMES collaboration published first evidence for azimuthal single-spin asymmetries in semi-inclusive production of charged pions on a transversely polarised hydrogen target. The measured asymmetries are caused by both the Collins and the Sivers mechanisms. Their distinctive Fourier components provide signals to previously unmeasured quantities: the transversity quark distributi ... More

It is known that a dominant QCD mechanism for the single transverse-spin asymmetry in hard processes is induced by the twist-3 quark-gluon correlations inside a hadron, combined with the soft-gluonic poles to produce the interfering phase for the associated partonic hard scattering. We show that the coupling of the relevant soft gluon to partonic subprocess can be systematically disentangled, ... More
