Search for New Physics in Single Top Channel at the LHC

TL;DR

This paper reviews recent searches for new physics involving single top quark production at the LHC, including FCNC processes and $W'$ boson searches by ATLAS and CMS, highlighting different analysis techniques and results.

Contribution

It summarizes three recent experimental analyses on single top production and new physics searches at the LHC, comparing methods and findings.

Findings

No evidence of new physics observed in the analyzed channels.

Constraints placed on FCNC processes and $W'$ boson properties.

Different analysis techniques show consistent results with the Standard Model.

Abstract

At the seventh International Workshop on the CKM Unitarity Triangle, a talk on the search for new physics in single top quark production at the LHC experiments was presented. Three analysis were shown: the search for single top quark production through FCNC processes performed by the ATLAS \cite{Aad:2008zzm}, the search for $W^{'}$ boson by ATLAS using the $tb$ resonance using the invariant mass distribution of the $tb$ system and the search for $W^{'}$ boson done by CMS \cite{Chatrchyan:2008aa} using boosted decision tree and the invariant mass distribution of the $tb$ system.
