Description

In a data sample of approximately 1.3 fb{sup -1} collected with the D0 detector between 2002 and 2006, the orbitally excited charm state D{sub s1}{sup {+-}}(2536) has been observed with a measured mass of 2535.7 {+-} 0.6(stat) {+-} 0.5(syst) MeV/c{sup 2} via the decay mode B{sub s}{sup 0} {yields} D{sub s1}{sup -}(2536){mu}{sup +} {nu}X. A first measurement is made of the branching ratio product Br({bar B} {yields} D{sub s1}{sup -}(2536){mu}{sup +}{nu}X) {center_dot} Br(D{sub s1}{sup -} {yields} D*{sup -} K{sub S}{sup 0}). Assuming that D{sub s1}{sup -}(2536) production in semileptonic decay is entirely from B{sub s}{sup 0}, an extraction of the ... continued below
