Seyed Yaser Ayazi, Saeid Paktinat Mehdiabadi
TL;DR
This paper uses measurements of s-channel single top quark production to set new constraints on the mass and interaction properties of hypothetical $W'$ bosons, providing novel limits in collider physics.
Contribution
It introduces a new method of constraining $W'$ bosons using collider measurements of single top production cross sections, which had not been done before.
Findings
$W'$ bosons interacting only to right-handed fermions are excluded below 1390 GeV.
First use of s-channel single top cross section measurements to constrain $W'$ phase space.
Both phenomenological and statistical approaches are employed to derive limits.
Abstract
An analysis is performed to constrain the boson production using the measurement of the s-channel single top quark production cross section. Both phenomenological and statistical approaches are examined and results are presented. In the best case, bosons that interact only to the right-handed fermions are excluded below 1390 GeV. To our knowledge, it is the first time that the measured cross section of the s-channel single top quark production from the colliders is used to rule out part of the phase space of the boson.
