This might win you a little bit of sensitivity, for example a 2-sigma hint from both experiments might get combined into a 3-sigmish one.Jesterhttps://www.blogger.com/profile/08947218566941608850noreply@blogger.comtag:blogger.com,1999:blog-2846514233477399562.post-87458218188790154732010-02-26T16:43:08.953+01:002010-02-26T16:43:08.953+01:00Hi there.

Forgive my naive question - suppose the Tevatron shuts down around the same time that the LHC closes for its year or so maintenance work in 2011/2... Would there be any sense (or possibility) of combining search data from both machines? Just a thought... I suspect they hold their data in different formats, so perhaps a full collaboration is impossible.Anonymoushttps://www.blogger.com/profile/07120031104432762826noreply@blogger.comtag:blogger.com,1999:blog-2846514233477399562.post-51703008733518048832010-02-15T22:53:14.665+01:002010-02-15T22:53:14.665+01:00Hi Jester,

It takes much more than 2 years to figure out the jet energy scale to the level of understanding that CDF and DZERO currently have. I think that despite the larger bounty of top quarks provided by 1/fb at 7 TeV running of the LHC, the top quark mass will be far better known by Tevatron measurements by the end of 2012. <br />Cheers,<br />T.a quantum diaries survivorhttp://www.scientificblogging.com/quantum_diaries_survivornoreply@blogger.comtag:blogger.com,1999:blog-2846514233477399562.post-26834783284063555422010-02-05T10:40:27.984+01:002010-02-05T10:40:27.984+01:00As far as I know the funding for Tevatron running ...As far as I know the funding for Tevatron running through 2012 is not secured yet.

So it's clear the Higgs, at least the standard model one, cannot suddenly pop out. But some new physics analysis have not been updated since 1 inverse femtobarn, so something new might show up there. I would not dismiss the good old Tevatron yet.<br /><br />Susy and other imaginary scenarios are similar to the heavy quark: LHC7 will gain a factor of 10-30 in events, for a 500 GeV pair-produced colored particles like gluinos or squarks.Jesterhttps://www.blogger.com/profile/08947218566941608850noreply@blogger.comtag:blogger.com,1999:blog-2846514233477399562.post-61365555220379159082010-02-04T15:56:57.941+01:002010-02-04T15:56:57.941+01:00But we're talking about the situation after 18...But we're talking about the situation after 18-24 months of running.

So this fact makes it unlikely that the relatively small addition of luminosity they will add in a year or two will change things too much.<br /><br />Best wishes<br />LMLuboš Motlhttps://www.blogger.com/profile/17487263983247488359noreply@blogger.comtag:blogger.com,1999:blog-2846514233477399562.post-18886522430750896392010-02-04T01:25:15.415+01:002010-02-04T01:25:15.415+01:00Hi, this is an excellent comparison.
