The measurement is performed by analysing events with a pair of electrons or muons, or one electron and one muon, and at least two jets, one of which is identified as originating from hadronisation of a bottom quark. The measured cross section is 239 ± 2 (stat.) ± 11 (syst.) ± 6 (lum.) pb, for an assumed top-quark mass of 172.5 GeV, in agreement with the prediction of the standard model. en_US dc.publisher Springer Verlag en_US dc.subject Hadron-Hadron Scattering en_US dc.subject Top physics en_US dc.title Measurement of the tt¯ production cross section in the dilepton channel in pp collisions at s√ = 8 TeV en_US dc.type Article kusw.kuauthor Bean, Alice kusw.kudepartment Physics and Astronomy en_US dc.identifier.doi 10.1007/JHEP02(2014)024 kusw.oaversion Scholarly/refereed, publisher version kusw.oapolicy This item meets KU Open Access policy criteria. dc.rights.accessrights openAccess
