Description

We present updates on gluon GPDs and the hadronic structure of the photon from lattice QCD. The challenges in calculating gluon GPDs will be discussed, along with preliminary results for matrix elements probing the nonperturbative structure of the resolved photon. The lattice QCD calculation of the nonperturbative structure of the photon is being performed on the RBC/UKQCD domain-wall fermion ensembles.
