Abstract
A search for W′
bosons decaying to a top and a bottom quark in final states
including an electron or a muon is performed with the CMS detector at the LHC. The
analyzed data correspond to an integrated luminosity of 138 fb−1
of proton-proton collisions
at a center-of-mass energy of 13 TeV. Good agreement with the standard model expectation
is observed and no evidence for the existence of the W′
boson is found over the mass range
examined. The largest observed deviation from the standard model expectation is found for
a W′
boson mass (mW
′) hypothesis of 3.8 TeV with a relative decay width of 1%, with a local
(global) significance of 2.6 (2.0) standard deviations. Upper limits on the production cross
sections of W′
bosons decaying to a top and a bottom quark are set. Left- and right-handed
W′
bosons with mW
′ below 3.9 and 4.3 TeV, respectively, are excluded at the 95% confdence
level, under the assumption that the new particle has a narrow decay width. Limits are
also set for relative decay widths up to 30%.
