| Apr 25, 2018 at 20:40 | comment | added | Nogueira | @Yoni, we have some freedom in chose the regularization here. Also, different regularizations will give different expressions. The only thing that holds here is that when we renormalizes our expressions we should get the same answer given an experimental input. | |
| Apr 22, 2018 at 15:32 | comment | added | Yoni | Raising the dead here, but shouldn't you treat $\frac{1}{(k^2-\Delta)^2}$ as a multiplication of two propagators and perform regularization to each of them separately? This yields a different expression, e.g. a $2m^2\Lambda^2$ term when in common-denominator form, which doesn't exist in your expression. I'm sure yours is correct, but I'm puzzled by why this is the case, more so due to Lê Dũng's answer. | |
