Studying the Quark Structure of the Proton in High Energy Proton-Proton Collisions at RHIC

摘要

This thesis presents the first measurement of single spin asymmetries from inclusive di-hadron production in polarized proton-proton collisions at Relativistic Heavy 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 sample are calculated for different ranges of invariant mass and transverse momentum of the pairs. Discussion of the results and projections of statistical uncertainties for future transverse running are presented.
