Abstract
We have searched for the decay B⃗ D(+)(s1)(2536)X and measured an upper limit for the inclusive branching fraction of B(B⃗ D(+)(s1)X)<0.96% at the 90% confidence level. This limit is small compared with the total expected B⃗ D(*)D(*)KX rate. Assuming factorization, the D+s1 decay constant is constrained to be f(D(+)(s1))<114 MeV at the 90% confidence level, at least 2.5 times smaller than that of D(+)(s).
