| Title | Polarized gluon pseudodistributions at short distances | ||||
| Abstract | We formulate the basic points of the pseudo-PDF approach to lattice calculation of polarized gluon PDFs. We present the results of our calculations of the one-loop corrections for the bilocal $G_{\mu \alpha}(z) \widetilde G_{\lambda \beta}(0)$ correlator of gluonic fields. Expressions are given for a general situation when all four indices are arbitrary,and also for specific combinations of indices corresponding to three matrix elements that contain the structures containing the twist-2 invariant amplitude related to the polarized PDF. We study the evolution properties of these matrix elements, and derive matching relations between Euclidean and light-cone Ioffe-time distributions. These relations are necessary for extraction of the polarized gluon distributions from the lattice data. | ||||
