Or, in other words: would some refinement in the computation of QCD contributions move $\sigma_{\rm SM}$ around by a couple of standard deviations?<br /><br />Informed optimists wrt BSM physics will always doubt that MC generators are to be trusted out of the box when strong interaction effects are all over the place...Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2846514233477399562.post-77150454737088846552011-04-05T01:26:51.687+01:002011-04-05T01:26:51.687+01:00Citation complaints on blog, where is the world he...Citation complaints on blog, where is the world heading to :-]. <br />I linked to newer papers on purpose because they fit to the 3.4 sigma signal in CDF and they discuss constraints from the LHC.Jesterhttps://www.blogger.com/profile/08947218566941608850noreply@blogger.comtag:blogger.com,1999:blog-2846514233477399562.post-12397260570994207992011-04-04T21:53:16.688+01:002011-04-04T21:53:16.688+01:00arXiv:0911.3237 seems to be older than either of t...<a href="http://arXiv.org/abs/0911.3237" rel="nofollow">arXiv:0911.3237</a> seems to be older than either of the papers you linked to for sextets and triplets, and examines both of them.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2846514233477399562.post-14228010318237856912011-04-04T17:32:03.723+01:002011-04-04T17:32:03.723+01:00Lubos, I see you too are thinking about the asymme...Lubos, I see you too are thinking about the asymmetry and the hidden changes of sign and handedness (todays post on MEG for example).<br /><br />I do not see how either of you will win the bet on the LHC finding supersymmetry, squarks or what, when perfectly good alternatives to the standard theory based on topology does discuss particles in a similiar manner and considers possibly stringy multidimensions. Such superspaces may not be supersymmetry in the sense some of you are now exploring.<br /><br />But thanks for the info and interest. I think we do indeed have to go beyond the usual ideas like just phase spaces or the "old language of various quantum theories- not to say these are wrong."<br /><br />The PeSlaL.
