摘要
介绍KLOE实验介子达利兹衰变中η|π~0介子的跃迁形状因子的测量结果以及在γγ碰撞中η|γγ衰变宽度的测定.升级后的探测器从2014年11月开始取数,评述了双光子物理的前景.
The KLOE results on the measurement of the transition form factors of theηand π~0 mesons in Dalitz decays are presented,and the determination of the Γ(η→γγ)inγγcollisions is also reported.The prospects forγγphysics of the new data-taking,started in November 2014 with the upgraded detector,are reviewed.
