I was wondering if there exists a general formula for Fourier transform integrals of this type, which appear frequently in qft
∫ddk(2π)dei→k⋅→x[logk2]n[k2]m,
where the metric is euclidean.
I know a general formula that holds in dimensional regularization for the same integrals without the log term, or for the integral with
n=1,m=0, but I cannot find anything similar for the integral above.. Does anyone know if these integrals can be regularized and have a closed expression? Even something for a fixed dimension
d would be cool.
Thank you so much!
