Mixing effects of the charmonium and four-quark components in Y(4260)*

We study the mixing effects of the charmonium and four-quark components in Y(4260) exotic mesons.
We have studied the four-quark structure of Y(4260) in the quark potential model and found a bound state whose energy close to Y(4260). The results have been reported in PoS Hadron2017 (2018) 109.
In order to understand the production mechanism for the electron and positron collider experiments,
the possibility of having the charmonium components should be discussed.
We introduce the effective interaction between four-quark and charmonium components and
report the results of  the mixing effects on the mass, wavefunction and production rate of Y(4260).
