Hi,
At Moriond, there were some interesting results show this morning. Have a look at their website for all presentations: https://indico.in2p3.fr/event/12279/ https://indico.in2p3.fr/event/12279/
Most notable: - Belle has updated their measurement of R(D*) with semileptonic tags. Their 2015 result was only using hadronic tags, but measured both R(D) and R(D*). It is consistent with both the SM and previous results, but the difference of the WA and the SM will be more significant. To make the new WA, they are working on the correlation with their 2015 result. R(D) with SL tags is more challenging, due to the lower purity. They do have plans to use hadronic tau decays in the future.
- Atlas does not see much B(s) -> mumu. They measure something like 0.9+1.1-0.8 x 10-9 for Bs. This is very correlated with their BR for Bd, as you can see from slide 18, due to their worse mass resolution. It is not really competitive with the CMS-LHCb combination.
- Gudrun Hiller showed a comparison of the B->K*mumu in the highest q2 bin. This is the first time that I have seen a data-theory comparison in this bin. Up to now we only compared the q2 bins below the Jpsi resonance. In the region above the psi(2S), there is some (known) from charmonium resonances, but the form factor uncertainty should be lower. She finds a good agreement with the SM in this so-called low-recoil region, however, there is still much room for NP as seen in the large recoil region.
Groeten Jeroen
Their web-page is down "under maintenance"... that'll be fun for Wednesday.... Nice talk, Jeroen. Bye-bye D0 tetraquark.

There is a maintenance of the INDICO pages. This is why they are not available.
There was a nice talk on the Young Scientist Forum by someone from BaBar. They have an (much) improved measurement of BF(B->D*3pi). The reason that this is interesting is because it serves as the normalisation for the R(D*) measurement using tau->3pi nu.
Cheers Jeroen

Isn't that the measurement Wormser told us would come out for Moriond?

Yes, I forgot about that announcement. Thanks for the recollection!
