The existence of a new massive charged gauge boson, known as W’, is proposed by many new physics scenarios. 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.
