Description
rg beta function RGBeta is a Mathematica package that allows the user to extract RG beta-functions up to loop order 4-3-3 for gauge, Yukawa, and quartic couplings, respectively, for a large class of 4D renormalizable models. If you use RGBeta, please cite arXiv:2101.08265..
bet365 argentina We calculate the two-loop renormalization group (RG) beta-function of a massless scalar field theory from the irreducible version of Polchinski's exact RG flow equation.
trang chủ fi88 dangkyfi88.org We calculate the two-loop renormalization group (RG) beta-function of a massless scalar field theory from the irreducible version of Polchinski's exact RG flow equation. To obtain the correct two-loop result within this method, it is necessary to take the full momentum-dependence of the irreducible four-point vertex and the six-point vertex into account. Although the same calculation within ...
