摘要:

利用Lambert W函数给出了四维O(N)线性西格玛模型有效势的大N极限.有效势与重整化群完全一致,并且它允许一个小的正耦合参数的幂的渐近展开。仔细考虑模型中存在的UV截止验证了大N极限的物理学。

英文摘要:

We give the large N limit of the effective potential for the O(N) linear sigma model in four dimensions in terms of the Lambert W function. The effective potential is fully consistent with the renormalization group, and it admits an asymptotic expansion in powers of a small positive coupling parameter. Careful consideration of the UV cutoff present in the model validates the physics of the large N limit.
