Abstract
Using the ARGUS detector at the e+e− storage ring DORIS II at DESY, we have obtained the first evidence for B meson decays into χc mesons. The inclusive branching ratio for the decay B → χc X was measured to the (1.05±0.35±0.25)% assuming no χc2 production. In addition, four candidates for the exclusive decay B± → χc1K± have been observed, corresponding to a branching ratio of (0.19 ± 0.13 ± 0.06)%.
