Novel analysis of the decays Psi - hcpi0 and Etac - xc0pi0
Novel analysis of the decays Psi - hcpi0 and Etac - xc0pi0
We show that in the transitions psi' -> h(c)pi(0) and eta '(c) -> chi(c0)pi(0) the contributions from charmed-meson loops are highly suppressed, in contrast to various other charmonium decays. We calculate the width of the psi' -> h(c)pi(0), which agrees with the recent BES-I...

We show that in the transitions psi' -> h(c)pi(0) and eta '(c) -> chi(c0)pi(0) the contributions from charmed-meson loops are highly suppressed, in contrast to various other charmonium decays. We calculate the width of the psi' -> h(c)pi(0), which agrees with the recent BES-III data, and predict the width of the eta '(c) -> chi(c0)pi(0), Gamma(eta '(c) -> chi(c0)pi(0)) = 1.5 +/- 0.4 keV. A confirmation of this prediction would also provide additional support for a recent analysis of psi' -> J/psi pi(0)(eta), where loops are claimed to play a prominent role. |
