BEEC: An event generator for simulating the Bc meson production at an e+e- collider

Abstract Themeson is a doubly heavy quark–antiquark bound state and carries flavors explicitly, which provides a fruitful laboratory for testing potential models and understanding the weak decay mechanisms for heavy flavors. In view of the prospects in physics at the hadronic colliders such as Tevatron and LHC, physics is attracting more and more attention. It has been shown that a high luminositycollider running around the-peak is also helpful for studying the properties ofmeson and...
