Hi all,
here I put just few links about semileptonic exclusive decay on the
recoil. They will b part of a more complete web page very soon.
MC distributions (lepton cuts and all analysis cuts applied)

NEW SCANS ON DATA ARE STILL MISSING
THE BIG ISSUE: how do we handle the exclusive-nonres MC in that mx
region? if we use our default reweighting we will do a mess. Let's discuss...
