Similarity renormalization group evolution of N N interactions within a subtractive renormalization scheme
... The renormalization group (RG) techniques have been successfully applied to analyze the scale dependence and the power counting scheme of NN iteractions in the con- text of ChEFT [5–7] and to derive ...

Predictions for neutrino structure functions
... We now systematically investigate the sensitivity of the theoretical predictions of ⌬ xF 3 upon a variety of factors including: renormalization scheme and scale, quark mass ef- fects, higher twist, isospin ...

NLO BFKL equation, running coupling and renormalization scales
... due to the vanishing of the second, third and fifth terms, and relatively small fourth and sixth terms. Hence, the decrease of the coupling is only felt as a single power 共 and indeed there is an increase of the coupling ...

Fierz transformations and renormalization schemes for fourquark operators
... Abstract. It has been shown that the choice of renormalization scheme is crucial for four-quark operators, in particular for neutral kaon mixing beyond the Standard Model. In the context of SMOM schemes, ...

Slow running of the gradient flow coupling from 200??MeV to 4??GeV inNf=3QCD
... A peculiar aspect of our finite volume renormalization scheme is that we are only interested in expectation values obtained in the zero topological sector [see Eq. (2.6)]. On the lattice, this is ...

EFFECTIVE FIELD THEORY ON MANIFOLDS WITH BOUNDARY Benjamin I. Albert A DISSERTATION in Mathematics
... In 4.1.4, we formulate Costello’s renormalization procedure on R n . We give explicit formulas whenever possible and fill in a few steps in the argument omitted by Costello, such as the introduction of what we ...
