Description
The unintegrated gluon distribution (UGD) encodes the gluon content in the proton in the high-energy domain and gives the probability that a gluon can be emitted by a colliding proton, with given longitudinal momentum fraction and transverse momentum. The UGD, being a nonperturbative quantity, it is not well known and several models for it have been introduced so far.
The diffractive electroproduction of $\rho$-meson can get access to the UGDs and distinguish among the existing models, exploiting the discriminating power of helicity amplitude ratios.
