Studying the Quark Structure of the Proton in High Energy Proton-Proton Collisions at RHIC
… Ion Collider. This measurement combines the transversity distribution function and a polarized di-hadron fragmentation function, therefore can be included in the global analysis as an independent measurement of quark transversity. Di-hadron single spin symmetries from currently available data …

Transverse Spin Structure of the Proton Studied in Semi–inclusive DIS
… the quark helicity distribution and the quark transversity distribution. The latter two are the differences of the number of quarks with their spins aligned and antialigned with the nucleon spin whose direction is longitudinal or respectively transversal to its momentum. The first two …

MEASUREMENTS OF TRANSVERSE SPIN DEPENDENT DI-PION AZIMUTHAL CORRELATION ASYMMETRY AND UNPOLARIZED DI-PION CROSS-SECTION IN PROTON-PROTON COLLISIONS AT A CENTER-OF-MASS ENERGY OF 200 GeV AT STAR
The transversity distribution function, $h_1^{q}(x)$, where $x$ is the longitudinal momentum fraction of the proton carried by quark $q$, encodes the proton's transverse spin structure at leading twist. Difficulties arise when extracting $h_1^q(x)$ due to its chiral-odd nature. However, it can be …

Measurement of target single-spin asymmetry in charged kaon electroproduction on a transversely polarized 3He target
… is to extract new information on the quark transversity distribution and the novel transverse-momentum-dependent Sivers function in the neutron. A semi-inclusive deep inelastic scattering experiment was performed at the Hall A of the Jefferson laboratory using 5.9 GeV electron beam and a …

Perturbative renormalization of proton observables in lattice QCD using domain wall fermions
… helicity distribution [delta] q(x) and quark transversity distribution [delta] q(x). Off-diagonal elements determine form factors and general parton distributions. Due to the Minkowskian nature of these matrix elements, they cannot be evaluated on a Euclidean lattice so one uses the operator …
