The s-Channel Single Top Quark Production as a Constraint for $W'$ Boson\n Contribution

An analysis is performed to constrain the $W'$ boson production using the\nmeasurement of the s-channel single top quark production cross section. Both\nphenomenological and statistical approaches are examined and results are\npresented. In the best case, $W'$ bosons that interact only to the right-handed\nfermions are excluded below 1390 GeV. To our knowledge, it is the first time\nthat the measured cross section of the s-channel single top quark production\nfrom the colliders is used to rule out part of the phase space of the $W'$\nboson.\n
