Belle的e+e湮没中的粲截面和粲偶素(类)态

Charm cross-section and charmonium(like) states in e+e- annihilation with Belle

T. Uglov

摘要:

本文报道了用BELLE方法测量过程e+e-->DD*,e+e-->DD,e+e-->DDpi的排它截面,首次观测到psi(4415)-> DD*2(2460)的棒衰变和新态Y(4660).此外,在4.05GeV/c2附近的另一个事件集群被报道。

英文摘要:

We report BELLE measurements of the exclusive cross sections for the processes e+e-->DD*, e+e-->DD, e+e-->DDpi, the first observation of psi(4415)-> DD*2(2460)bar decay and new state, Y(4660), using ISR. In addition, another cluster of events at around 4.05GeV/c2 is reported.
