Query: Regge and factorized GPD models in $\rho^0$ elastic electroproduction   A possibility to study Regge and factorized parameterizations of generalized
parton distributions in hard electroproduction of $\rho^0$ on the proton is
considered. For that the dependences of the differential cross sections on the
transferred momentum for these parameterizations are compared.
