High $p_T$ Jet Physics at CMS

We present CMS plans to search for physics beyond the standard model using high $p_T$ jets. The inclusive cross section as a function of jet $p_T$ 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 $\Lambda^+$ 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.
