  Same-sign $W$ boson pairs production is a promising channel to look for
signatures of double parton interactions at the LHC. The corresponding cross
section has been calculated by using double parton distribution functions,
encoding two parton correlations, evaluated in a Light-Front quark model. The
obtained result is in line with previous estimates which make use of an
external parameter, the so called effective cross section, not necessary in our
approach. The possibility to observe for the first time two-parton
correlations, in the next LHC runs, has been established.
