Search for High-Mass States with Lepton Plus Missing Transverse Energy Using the ATLAS Detector at Center-of-Mass Energy of 7 TeV

TL;DR

This paper reports a search for high-mass particles like W' bosons decaying into a lepton and neutrino using ATLAS data at 7 TeV, aiming to discover new physics beyond the Standard Model.

Contribution

It presents the first search for W' bosons in the lepton plus missing energy channel at 7 TeV with 1.04 fb^-1 of data from the LHC.

Findings

No significant excess observed over the Standard Model background.

Set new limits on the mass of W' bosons.

Improved sensitivity compared to previous searches.

Abstract

The ATLAS detector has been used to search for high-mass states decaying into a single high momentum lepton and missing transverse energy, such as new heavy charged gauge bosons. The latest search results for a W Prime boson decaying to lepton plus neutrino in 1.04 fb^-1 of proton-proton collisions at a center of mass energy of 7 TeV produced at the Large Hadron Collider are presented.
