Supermodels for early LHC

TL;DR

This paper introduces 'supermodels' that can detect new physics signatures at the LHC with minimal data, surpassing Tevatron sensitivity, by focusing on simple, high-visibility final states with low background.

Contribution

The paper proposes the concept of supermodels that enable early LHC discovery of new physics with limited data, emphasizing s-channel resonances and straightforward search strategies.

Findings

Supermodels can outperform Tevatron with only 10 pb^-1 of LHC data.

Simple s-channel resonance models are effective for early discovery.

Searches for these models are feasible with low-background final states.

Abstract

We investigate what new physics signatures the LHC can discover in the 2009-2010 run, beyond the expected sensitivity of the Tevatron data by 2010. We construct "supermodels", for which the LHC sensitivity even with only 10 inverse picobarn is greater than that of the Tevatron with 10 inverse femtobarn. The simplest supermodels involve s-channel resonances in the quark-antiquark and especially in the quark-quark channels. We concentrate on easily visible final states with small standard model backgrounds, and find that there are simple searches, besides those for Z' states, which could discover new physics in early LHC data. Many of these are well-suited to test searches for "more conventional" models, often discussed for multi-inverse femtobarn data sets.
