ATLAS has released new top quark mass measurements using the dilepton and all hadronic channels.
The measurement in the all hadronic channel is:
mtop = 173.80 ± 0.55(stat.) ± 1.01(syst.) GeV is measured, where the systematic uncertainty is dominated by the hadronization modelling (0.64 GeV) and the jet energy scale (0.60 GeV).
The measurement in the dilepton channel is:
mtop = 172.99 ± 0.41(stat.) ± 0.74(syst.) GeV is obtained, where the systematic uncertainty is dominated by the jet energy scale (0.54 GeV).
This result is combined with the ATLAS top-quark mass measurements in the single-lepton and dilepton channels performed at √ s = 7 TeV [4] using the Best Linear Unbiased Estimate method [5]. The combined measurement gives a combined top-quark mass value of: mtop = 172.84 ± 0.34(stat.) ± 0.61(syst.) GeV.A new CMS measurement of the top quark mass in a new channel with low precision was released in August. A new CMS measurement of the top quark mass in an old, more precise channel was released in March.
I added you back into my sidebar. Blogger is acting up, trying to fix things.
ReplyDeleteThanks! I appreciate it, but you are, of course, welcome to decide which links to put up in your blog as you see fit.
ReplyDeleteBlogger deleted all of my links and I lost two gadgets as well. I had to manually put in every blog, and I'm still missing two or three. Could have been operator error, who knows.
