This paper evaluates ATLAS's ability to discover new high-mass resonances like Z', leptoquarks, gravitons, and W' in leptonic final states at 14 TeV, highlighting early data's potential to surpass current limits.

Contribution

It provides an analysis of the discovery potential for various new resonances at the LHC's 14 TeV energy using ATLAS, including early data prospects.

Findings

Early runs with tens of pb^-1 can surpass current limits.

High-mass resonances like Z', W', leptoquarks, and gravitons are detectable at 14 TeV.

Potential for discovery with limited initial data is significant.

Abstract

This paper describes the discovery potential for new resonances with the ATLAS experiment. The resonances discussed in here are the Z', leptoquarks, graviton and W' resonances in some of their leptonic final states, considering a center-of-mass energy of 14 TeV for all of them, and an estimation of the potential of the W' search at the early center-of-mass energy of the LHC . The studied scenarios show that an initial run of few tens of 1/pb would be enough to go beyond the current limits in most of these models.
