CMS-PHO-EVENTS-2022-016-6  -  Small, Medium, Large, Original
Two quark-antiquark pairs can simultaneously annihilate, in DPS, leading to the production of two W bosons of the same charge.

CMS-PHO-EVENTS-2022-016-1  -  Small, Medium, Large, Original
An event seen in the CMS detector from proton-proton collisions at a center-of-mass energy of 13 TeV. Two same-charge muons (red tracks), probably resulting from the decay of two W bosons produced by double parton scattering, fly out of the collision point. The missing transverse energy of the neutrinos from the W boson decays is shown by the blue arrow.

CMS-PHO-EVENTS-2022-016-2  -  Small, Medium, Large, Original
An event seen in the CMS detector from proton-proton collisions at a center-of-mass energy of 13 TeV. An electron (represented by the green line) and a muon (represented by the red line), both with the same charge, probably result from the decay of two W bosons produced by double parton scattering. The missing transverse energy of the neutrinos from the W boson decays is shown by the blue arrow.

CMS-PHO-EVENTS-2022-016-4  -  Small, Medium, Large, Original
Effective cross section measured at the Tevatron (CDF and D0) and at the LHC (ATLAS and CMS) in several production channels and collision energies. The result described here is represented in the lowest row (red point).
