摘　　要：从实验和理论上对类粲偶素Z_(c)(3900)^(0)的研究有助于人们加深对强相互作用的理解.通过等效拉氏量方法和单玻色子交换模型,对类粲偶素Z_(c)(3900)^(0)的光生问题进行研究,给出产生截面、微分截面角分布及最佳探测能量窗口.同时讨论不同耦合方式和模型参数对结果的影响,这对光生实验进一步研究Z_(c)(3900)^(0)具有重要参考意义.The research of the charmonium-like state Z_(c)(3900)^(0) through experimental and theoretical approaches will be conducive to deepen our understanding of the QCD confinement.The photoproduction of the charmonium-like state Z_(c)(3900)^(0) is explored by virtue of the effective Lagrangian and one-boson-exchange model,where the cross section,the angular momentum distribution and the best energy window are obtained.The effects from different coupling and model parmeters are also implemented,which should be meaningful for the search of Z_(c)(3900)^(0) experimentally.
