Abstract
In a data sample of approximately 1.3 fb-1 collected with the D0 detector between 2002 and 2006, the orbitally excited charm state Ds1±(2536) has been observed with a measured mass of 2535.7±0.6(stat)±0.5(syst) MeV/c2 via the decay mode Bs0→Ds1-(2536)µ+vµX. A first measurement is made of the branching ratio product Br(b̅ →Ds1-(2536)µ+vµX)×Br(Ds1-→D∗-KS0). Assuming that Ds1-(2536) production in semileptonic decay is entirely from Bs0, an extraction of the semileptonic branching ratio Br(Bs0→Ds1-(2536)µ+vµX) is made.
