The new W mass is out, and still… December 15, 2006

Posted by dorigo in news, physics, science.

Still one week to go before I can put the number here, darn!

The thing is, despite the procedure having been scrutinized, the blinded result analyzed, and all the rest, there is still a formal step to do before making the number public: the blessing. I thought I could write down a number here, but I have to reckon that the result is only pre-blessed today.

I know the number however, and I can say it is not going to change the picture much. The low value of the preferred Higgs mass remains low, the world W mass measurement will remain close to where it is, and everybody can sleep tight tonight – no big surprises.

SLOW DOWN! Pleeassse! I’m talking to CDF and D0 in general here. Us poor theory suckers need more time to calculate the mass.

Hi Kea,

how do you calculate the W mass ? You mean by perfecting electroweak fits or by means of some new piece of magic ? Can I get to know something more about it ?

… And besides: there’s no slowing down possible… Actually if you look at it CDF and D0 were very sympathetic with such a request, since CDF has now a measurement with only little more than a tenth of the data they collected, and D0 has no new measurements since Run I…

I mean new magic – but we (meaning 3 or 4 people) are still a long way from the W mass. First, Brannen’s lepton mass calculations need to be perfected. See links on my blog. Cheers.
