A method to rescale experimental data with dependence on $Q^2$ for DVCS process

Abstract

We investigate the procedure for rescaling the DVCS cross section data collected with different invariant mass, $W$, of the virtual photon - proton system. We suggest a method which makes the rescaling more functional to conduct statistical analysis on overall data. The study can be applied to rescale data collected with different photon virtuality $Q^2$. Also we show a dependence on $Q^2$ for the $\delta$ parameter, that is used to describe the cross section as a function of $W$.
