LHC seminar: Search for new physics with b→sℓ+ℓ− decays at L

Post by mfb » Tue Apr 11, 2017 3:21 pm

Tuesday next week: Indico link

Based on what was shown in Moriond, I expect it to be an interesting seminar.

Hmm, the paper is still in circulation. The first comment deadline is Friday. I'm surprised this seminar is scheduled so soon after that. Obviously I won't spoil it, but there's a practice talk on Thursday so I'll know then if the results are actually on the slides or not.

I'll take your post as confirmation that there are updates with respect to Moriond (not necessarily in the seminar, but soon).

Since I can see the draft of the LHCb public page, I can confirm that the result in the two unblinded q^2 bins will be shown in this seminar.

I'm fairly sure the error bars have gotten bigger since last I saw them, but that's what internal reviews are for...

B0 -> K* mu mu to B0 -> K* e e branching fraction ratio.

Muons are too rare by 2.2-2.4 sigma in the lowest q-bin and too rare by 2.4-2.5 sigma in the intermediate bin. Not very significant, but going in the same direction as all other results.

Run 2 data should lead to clarity.
