"Using Semileptonic Decays to search for two gluon couplings in the Eta-prime "
 Slideshow (PDF)
Large branching fractions for hadronic B decays involving the eta^prime (1997) and also in the B semileptonic decay to the eta^prime (2006) could potentially be caused by the extra 2-gluon couplings from the singlet component of the eta^prime meson. Now, for CLEO-C, we look to semileptonic decays of the D meson to the eta^prime to see if there is evidence for enhancement there as well. We make improvements to the “neutrino reconstruction” method used to study B decays, and find that the new algorithm can also be used to simultaneously measure a large number of D hadronic decays as well.
