ϒ(nl) decay into B(⁎)B¯(⁎)
We have evaluated the decay modes of the ϒ(4s),ϒ(3d),ϒ(5s),ϒ(6s) states into BB¯,BB¯⁎+c.c.,B⁎B¯⁎,BsB¯s,BsB¯s⁎+c.c.,Bs⁎B¯s⁎ using the P03 model to hadronize the bb¯ vector seed, fitting some parameters to the data. We observe that the ϒ(4s) state has an abnormally large amount of meson-meson componen...
