Abstract: (Springer)

Searches are presented for heavy gauge bosons decaying into a top and a bottom quark in data collected by the CMS experiment at

\sqrt{s}=13

TeV that correspond to an integrated luminosity of 2.2 and 2.6 fb

^{−1}

in 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 W′ boson (W′

_{R}

) and the combined analyses exclude at 95% confidence level W′

_{R}

with masses below 2.4 TeV if

{M}_{\mathrm{W}{\prime}_{\mathrm{R}}}\gg {M}_{\nu_{\mathrm{R}}}

(mass of the right-handed neutrino), and below 2.6 TeV if

{M}_{\mathrm{W}{\prime}_{\mathrm{R}}}<{M}_{\nu_{\mathrm{R}}}

. The results provide the most stringent limits for right-handed W′ bosons in the top and bottom quark decay channel.
