This is a lot of data, and should allow CMS and ATLAS to surpass handily the sensitivity of D0 and CDF to most signals of new physics, the most important exception being the Higgs boson at low masses. Concerning running at 7 TeV instead of 10 TeV, the cost is roughly a factor of two in integrated luminosity for most standard model processes, so we can do much better measurements with 1 fb-1 at 7 TeV than with 0.2 fb-1 at 10 TeV. The data sets become roughly equal when you consider the production of new heavy states, such as squarks and gluinos, leptoquarks, extra gauge bosons, etc.Michaelhttp://muon.wordpress.com/noreply@blogger.comtag:blogger.com,1999:blog-34480619.post-70261699577645547812010-02-12T09:47:45.554-06:002010-02-12T09:47:45.554-06:00Maybe 3.5 TeV per beam, making the center of mass ...Maybe 3.5 TeV per beam, making the center of mass energy of 7 TeV?<br /><br />Zz.ZapperZhttps://www.blogger.com/profile/15861398273820851809noreply@blogger.comtag:blogger.com,1999:blog-34480619.post-29512549257751314722010-02-12T09:40:55.389-06:002010-02-12T09:40:55.389-06:00I may be totally off here, but I could have sworn ...I may be totally off here, but I could have sworn that just the other day I read a peice about the LHC running at 3.5 TeV through the end of 2010, than it going on a year-long hiatus and than possibly ramping it up to 7 TeV... Am I mistaken?Anonymousnoreply@blogger.com
