                                    A first search for same-sign WW production via double-parton scattering
is performed based on proton-proton collision data at a center-of-mass
energy of 8 TeV using dimuon and electron-muon final states. The search
is based on the analysis of data corresponding to an integrated
luminosity of 19.7 fb-1. No significant excess of events is
observed above the expected single-parton scattering yields. A 95%
confidence level upper limit of 0.32 pb is set on the inclusive cross
section for same-sign WW production via the double-parton scattering
process. This upper limit is used to place a 95% confidence level lower
limit of 12.2 mb on the effective double-parton cross section parameter,
closely related to the transverse distribution of partons in the proton.
This limit on the effective cross section is consistent with previous
measurements as well as with Monte Carlo event generator predictions.
