强子口袋半径及高能情况下的强耦合常数

摘要

according to the relationship between the strong interaction force range and strong coupling constant among quarks in a hadron, a brief computational method on the pocket radius of a hadron is given in this paper. The strong coupling constant at high energy is also calculated and quite consistent with the experimental value made at at Tevatron -p p Collider.%根据夸克间强相互作用力程随强跑动耦合常数的变化关系,给出了强子口袋半径的一种简明的计算方法.同时计算了高能情况下的强耦合常数,与最近Tevatron对撞机上的实验结果相比较,吻合较好.
