Heavy Meson Masses and Decay Constants
Rosner, Jonathan L.
Original · EN
Masses and decay constants of mesons containing a single c or b quark are described within the framework of heavy-quark symmetry. The Bₛ* - Bₛ and B*⁰ - B⁰ mass splittings are found equal to within a fraction of an MeV. Decay constants of D and B mesons are estimated using isospin mass splittings in the D, D*, B, and B* states to isolate the electromagnetic hyperfine interaction between quarks. A relation following from the use of splittings in kaons is also considered.
