Session V15 - Heavy Flavors III.
MIXED session, Tuesday morning, May 02
202B, LBCC
We present results from semileptonic charm decays in the FOCUS (E831) photoproduction experiment. FOCUS collected data during the 1996--1997 fixed target run at Fermilab. Starting from a sample of about 80,000 reconstructed D^+ \rightarrow \barK^*0 \, \ell^+ \nu events, we present preliminary form factor measurements and branching ratios for decays such as D^+ \rightarrow \barK^*0 \, \ell^+ \nu and D_s^+ \rightarrow \, \phi \ell^+ \nu.
