Yang-Mills at the LHC

The LHC schedule for 2007 means that we won’t be looking at new physics until 2008. But there is a lot of work to do before then! The 450 Gev calibration run is now planned for November 2007. The LHC will be interesting for heavy ion physics. One important process is gg fusion, but it is said that final state effects such as energy loss will make quantification difficult unless we can better understand such processes.

Fortunately twistor string theory has made great advances with the MHV diagram technique, which creates Feynman trees from maximal helicity violating vertices. Maybe we have time to improve on this a little.
