中性top介子在NLC实验中的可能物理迹象

The Possible Signature of the Neutral top Pion at NLC

ＴＣ２模型预言的物理ｔｏｐ介子通过反常可以与规范玻色子（γ，Ｚ）发生耦合，因此在高能ｅ＋ｅ－碰撞中可以产生这种粒子．本文估计了中性ｔｏｐ介子πｔ°在ＮＬＣ实验中的产生几率，并讨论了其可能的物理迹象．

The nentral top pion π° t can couple to gange bisons (γ,Z) through anomalies.Thus,it can be produced in high energy e +e - collisions.In this paper,we estimate the production cross section of π° t at the NLC experiment and discuss the possible physical signature.
