New physics at ATLAS and CMS with the first data

A new era in particle physics is about to begin. The long-awaited $pp$ collisions at LHC will take place later this year. The two general purpose experiments, ATLAS and CMS, will collect first physics data in collisions of 5 TeV proton beams, by which $\sim$200 \pbinv total data is expected to be delivered by the end of the first 2009-2010 run. The ATLAS and CMS detectors are designed as discovery machines for the missing piece in Standard Model --the Higgs boson-- and for physics beyond the Standard Model. Both experiments have conducted detailed analyses to show the discovery potential for new physics, including SUSY, extra dimensions, and new heavy resonances. In this note, after giving a brief overview of the status of the two experiments, I will present results from ATLAS and CMS studies for the expected new physics reach with early LHC data.
