Measurement of the
Moments of the Hadronic Invariant Mass Distribution
in Semileptonic B Decays
This is the WEB page summarizing the blessed results for the measurement
of the first two moments of the hadronic invariant masss squared distribution
in semileptonic B decays. These results are used to determine the
dominant HQET expansion parameters. The results have been blessed
in the B
Physcis Meeting on Thursday April 28, 2004.
There is a complete version of the results:
