[Clas12_dileptons] HERA J/psi photoproduction data

[Pawel Nadel-Turonski]

Hello Everyone,

Please find below the link to Bjoern Schenke’s slides.

https://indico.cfnssbu.physics.sunysb.edu/event/322/

The plot that I showed is on slide 12. There is also a reference there to one of Bjoern’s theory paper (although without the gluonic radius estimates). There are also references to the H1 and ZEUS J/psi photoproduction data within. I can give you more details is you like. The papers should also include the definition of the exponential t-slope B_G. W is the gamma-p c.m. energy. This is also essentially the x-dependence since tau ~ Q’^2 / W^2, where Q’ = M_J/psi.

Best,

Pawel
