Description
Generalized parton distributions (GPD) are being extensively used to describe hard exclusive hadron processes.
Twist-2 photon GPDs has been previously derived by calculation of the photon-photon electromagnetic scattering amplitude.
These distributions may give contribution to the ultraperipheral light-by-light processes in heavy ion collisions recently observed at the LHC.
New method of analytic continuation of GPD for different kinematical regions applied on the photon GPDs and model distributions.
