孤子和自旋Skyrmion的相对论集体坐标系

Relativistic Collective Coordinate System of Solitons and Spinning Skyrmion

Hiroyuki Hata, Toru Kikuchi

摘要:

我们考虑根据一个简单的原则构造场论孤子的相对论集体坐标系:集体坐标必须以这样一种方式引入静态解,即集体坐标的运动方程保证原场论的运动方程。作为一个例子,我们应用这一原则的自旋运动的Skyrmion的量子化,通过将领先的相对论修正的刚体近似。我们计算了核子的衰变常数和各种静态性质,发现相对论修正在5% -20%范围内。我们还研究了如何重子变形,由于自旋运动。

英文摘要:

We consider constructing the relativistic system of collective coordinates of a field theory soliton on the basis of a simple principle: The collective coordinates must be introduced into the static solution in such a way that the equation of motion of the collective coordinates ensures that of the original field theory. As an illustration, we apply this principle to the quantization of spinning motion of the Skyrmion by incorporating the leading relativistic correction to the rigid body approximation. We calculate the decay constant and various static properties of nucleons, and find that the relativistic corrections are in the range of 5% -- 20%. We also examine how the baryons deform due to the spinning motion.
