Erm, just some statistical queries.. what about chebychev's inequality:

http://en.wikipedia.org/wiki/Chebyshev's_inequality

"No more than 1/k^{2} of the distribution's values can be more than k standard deviations away from the mean" 

In this case it is 1/(3.7*3.7) which is 7%, and 24*7% is 1.75, so no more than 1.75 of the observables should be this far away. One deviation this large is perfectly expected from Chebychev's inequality.

Thanks,

 

Rob

Dear bfys-physics friend,

This is to let you know that I collect comments to the paper below.

To stimulate you to read it: we claim that the probability that the measurement is consistent with the Standard Model is only 0.5%. A local discrepancy of 3.7 sigma is observed.

  LHCb PAPER-2013-037:
      "Measurement of form factor independent observables
       in the decay $B^0\to K^{*0}\mu^+\mu^-$"
      Link            : https://cds.cern.ch/record/1557918
      Deadline        : 09-Jul-2013

best regards,

- Marcel
