Hi friends!
This is the highlight of EPS, if you ask me! You should definitely read this: http://arxiv.org/pdf/1307.5683v1.pdf
The authors fitted for the Wilson coeficients C7 and C9, and a single shift of C9 could explain all tensions in the observed angular distributions by LHCb.
They claim 3.7sigma deviation (4.5 sigma at 1<q2<6) and speculate about the existence of a Z' gauge boson...
Cheers, Niels
