Parton correlations in same-sign $W$ pair production via double parton scattering at the LHC

Understand

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.
