SciPost IFF and Collins Results Proceeding (DIS 2021)
Details
Conference
DIS2021
(DIS-2021 is the 28th in the series of annual workshops on Deep-Inelastic Scattering (DIS) and Related Subjects. The conference covers a large spectrum of topics in high energy physics. A significant part of the program is devoted to the most recent results from large experiments at BNL, CERN, DESY, FNAL, JLab and KEK. Theoretical advances are included as well.)
Abstract
At the leading twist, the transversity distribution function,
h1q(x), where x is the longitudinal momentum fraction of the proton carried by quark q, encodes the transverse spin structure of the nucleon. Extraction of it is difficult because of its chiral-odd nature. In transversely polarized proton-proton collisions (p↑p), h1q(x) can be coupled with another chiral-odd partner, a spin-dependent fragmentation function (FF). The resulting asymmetries in hadron(s) azimuthal correlations directly probe h1q(x). We report the measurement of correlation asymmetries for charged pion(s) in p↑p, through the Collins and the Interference FF channel.
