Searches are presented for heavy gauge bosons decaying into a top and a bottom quark in data collected by the CMS experiment at s=13 TeV that correspond to an integrated luminosity of 2.2 and 2.6 fbâ1in the leptonic and hadronic analyses, respectively. Two final states are analyzed, one containing a single electron, or muon, and missing transverse momentum, and the other containing multiple jets and no electrons or muons. No evidence is found for a right-handed Wâ² boson (Wâ²R) and the combined analyses exclude at 95% confidence level Wâ²Rwith masses below 2.4 TeV if MWâ²Râ«MνR (mass of the right-handed neutrino), and below 2.6 TeV if MWâ²R<MνR. The results provide the most stringent limits for right-handed Wâ² bosons in the top and bottom quark decay channel.[Figure not available: see fulltext.].

Abstract
Searches are presented for heavy gauge bosons decaying into a top and a bottom quark in data collected by the CMS experiment at s=13 TeV that correspond to an integrated luminosity of 2.2 and 2.6 fbâ1in the leptonic and hadronic analyses, respectively. Two final states are analyzed, one containing a single electron, or muon, and missing transverse momentum, and the other containing multiple jets and no electrons or muons. No evidence is found for a right-handed Wâ² boson (Wâ²R) and the combined analyses exclude at 95% confidence level Wâ²Rwith masses below 2.4 TeV if MWâ²Râ«MνR (mass of the right-handed neutrino), and below 2.6 TeV if MWâ²RI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
