Abstract

We present CMS plans to search for physics beyond the standard model using high pT jets. The inclusive cross section as a function of jet pT is a first simple measure of QCD dijets which is sensitive to a 3 TeV contact interaction with only 10 pb−1. With the dijet mass distribution we expect to be able to observe dijet resonances with large cross sections, such as a 2 TeV excited quark which produces a convincing signal with only 100 pb−1. With the dijet ratio, a simple angular measurement, we expect to be able to discover a contact interaction scale Λ+ of 4, 7 and 10 TeV for integrated luminosities of 10 pb−1, 100 pb−1, and 1 fb−1 respectively. Using the dijet ratio we can discover or confirm a dijet resonance, and eventually measure its spin. With 100 pb−1 a 2 TeV resonance with the production rate of an excited quark produces a convincing signal in the dijet ratio.
