Search for Semileptonic Decays of Photoproduced Charmed Mesons
- Illinois U., Urbana
In the broad band neutral beam at Fermilab, a search for photoproduction of charmed D mesons has been done using photons of 100 to 300 GeV. The reaction considered was $$\gamma + Be \to D_{\to (K^0_s\eta \pi^{\pm})}\overline{D}_{\to (Leptons + \dots)} + X$$ No statistically significant evidence for D production is observed based on the $$K^0_s \eta \pi^{\pm}$$ mass spectrum. The sensitivity of the search is commensurate with theoretical estimates of $$\sigma(\gamma\rho \to D\overline{D} + X) \sim$$ 500 nb, however this is dependent on branching ratios and photoproduction models. An appendix contains data on a similar search for semileptonic decays of charmed baryons.
