Hi all, I've performed the check on the mES histogram used for the computation of data semileptonic events. Results/considerations can be found in http://www.slac.stanford.edu/~asarti/recoil/valid/mesvalid.html My conclusions are that we can safely assume that effect we're seeing comes from mES fit technology and NOT from analysis bias/errors. So, if you agreee, I will concentrate from now on, on the q2 (q2,mx) analysis. Otherwise, please fell free to suggest additionalchecks that you'd like to see. Cheers, Alessio ______________________________________________________ Alessio Sarti Universita' & I.N.F.N.
