Hi Patrick,yes, please scratch and scratch again. I would have bet that D0 is wrong. Now with LHCb reporting the same it's becoming more serious.
Yes, we are still scratching our heads to see if we did not make a mistake, but we really cannot find anything strange.
:-) We'll need to wait for a few days until the excitement about Mrs Einstein cools down.
Unfortunately, today CERN announced this new Higgs result which will put our nice result in shadows. See:

_______________________________________________Hi Jacco,
This is amazing. This is likely to be LHCb's result of the year. What's the publication plan? I've seen a draft pass by but did not look. PRL or better? That could make Nature Physics for instance.
How correlated are our asls and asld measurements? Can we make an ellipse on that plot?
Cheers,
Patrick

Dear all,
We are proud to present you the highly anticipated unblinded value of asls. Please keep it within the group for now, as we are yet to present the official LHCb result. In the attached plot you can see the new world average for asls (y-axis) as a green band, as well as the combined result for asld (x-axis) and the D0 dimuon anomaly (yellow ellips).
We confirm the D0 result, and are in agreement with the SM prediction within 4.1 standard deviations. The deviation can most likely be attributed to an anomalous branching ratio of the Bs -> tau tau intermediate state, or processes involving the Z’ in the mixing.
Cheers, on behalf of the asls crew,
Jacco
