Spectrum of c mesons • Picture on c mesons still incomplete – established are D s , D s * , D s1 , D s2 • Candidates for lowest, missing J P =0 + ,1 + states (discovered in 2003) D sJ* (2317) (→D s π 0 ) m=2317.4±0.9 MeV, Γ
• Put further experimental constraints on the two states D sJ studies at Babar • Comprehensive, exclusive study for e + e - →c fragmentation processes – investigation of D s π 0 , D s γ, D s π 0 γ, D s π 0 π 0 , D s γγ, D s π + π - final states – measurement of branching ratios, masses and widths – search for doubly charged / neutral D sJ *(2317) partners in D s π ± system (predicted by some molecule models) • Inclusive study of B→D (*) D sJ decays – measurement of absolute branching fractions M.
