The data sample corresponds to an integrated luminosity of 138 invfb recorded at a center-of-mass energy of 13 TeV using the CMS detector at the CERN LHC. Multivariate discriminants are used to distinguish the signal process from the main backgrounds. A binned maximum likelihood fit is performed to extract the signal cross section. The measured cross section for production of same-sign W bosons decaying leptonically is 80.7 +/- 11.2 (stat) {+9.5}{-8.6} (syst) +/- 12.1 (model) fb, whereas the measured fiducial cross section is 6.28 +/- 0.81 (stat) +/- 0.69 (syst) +/- 0.37 (model) fb. The observed significance of the signal is 6.2 standard deviations above the background-only hypothesis.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.130562.v1/t1","@type":"Dataset","description":"Measured values of inclusive and fiducial cross section for same-sign WW bosons via DPS","name":"Table1"},{"@id":"https://doi.org/10.17182/hepdata.130562.v1/t2","@type":"Dataset","description":"Effective DPS cross section paramater","name":"Table2"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2091619?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/130562"}],"inLanguage":"en","name":"Observation of same-sign WW production from double parton scattering in proton-proton collisions at $\\sqrt{s}$ = 13 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2091619?version=1","version":1}
