When W’ decays to tb, the final state is very similar to the final state of the s-channel single top production, where W boson is the off-shell mediator to produce the top and bottom quarks. If W’ exists, it can affect the cross section of the SM s-channel single top production, so measuring this cross section can constrain the W’ contribution. We use different data categories from CMS and ATLAS experiments to constrain this contribution. Assuming a pure left-handed (right-handed) W’ gives a lower limit of 1290 (1360) GeV at 95% Confidence Level on the mass of W’. If the coupling coefficient is increased to 1.8, the lower limit on the W’ mass can exceed 1900 GeV, in special cases.
