### Abstract

We have searched for the decay (Formula presented) and measured an upper limit for the inclusive branching fraction of (Formula presented) at the 90% confidence level. This limit is small compared with the total expected (Formula presented) rate. Assuming factorization, the (Formula presented) decay constant is constrained to be (Formula presented)<114 MeV at the 90% confidence level, at least 2.5 times smaller than that of (Formula presented).
