X(3872)为1D 2粲偶素态

X(3872) as a 1D2 charmonium state

Yu. S. Kalashnikova, A. V. Nefediev

摘要:

根据BABAR合作组最近的一个结果,考虑了X(3872)介子的1D 2粲偶素分配,认为X介子的量子数为2 +.结果表明,X(3872)的既定性质与1D 2 c-反c分配存在激烈冲突。

英文摘要:

The 1D2 charmonium assignment for the X(3872) meson is considered, as prompted by a recent result from the BABAR Collaboration, favouring 2-+ quantum numbers for the X. It is shown that established properties of the X(3872) are in a drastic conflict with the 1D2 c-anti-c assignment.
