Vector Meson production from NLL BFKL
Dmitry Yu. Ivanov, Alessandro Papa · arXiv (Cornell University) · 2007
The amplitude for the forward electroproduction of two light vector mesons can be written completely within perturbative QCD in the Regge limit with next-to-leading accuracy, thus providing the first example of a physical application of the BFKL approach at the next-to-leading order. We study in the case of equal photon virtualities the main systematic effects, by considering a different representation of the amplitude and different optimization methods of the perturbative series.
