Skewed Sudakov Regime, Harmonic Numbers, and Multiple Polylogarithms
Victor T. Kim, Victor A. Matveev, Grigorii B. Pivovarov
On the example of massless QED we study an asymptotic of the vertex when only one of the two virtualities of the external fermions is sent to zero. We call this regime the skewed S…
Gell-Mann--Low scheme for the Standard Model
Grigorii B. Pivovarov
I describe a version of the Gell-Mann--Low scheme which is applicable to the Standard Model. First, I give a procedure for extracting input parameters of the theory from the Green'…
Naturalness and Renormalization Group in the Standard Model
Grigorii B. Pivovarov
I define a naturalness criterion formalizing the intuitive notion of naturalness discussed in the literature. After that, using as an example, I demonstrate that a theory may…
Non-perturbative renormalization: a new way
G. B. Pivovarov
The notion of non-perturbative renormalization is discussed and extended. Within the extended picture, a new non-perturbative representation for the generating functional of Green…
Multi-particle Processes and Tamed Ultraviolet Divergences
Victor Kim, Grigorii Pivovarov
New approach to computing the amplitudes of multi-particle processes in renormalizable quantum field theories is presented. Its major feature is a separation of the renormalization…
The inaction approach to gauge theories
Grigorii Pivovarov
The inaction approach introduced previously for phi^4 is generalized to gauge theories. It combines the advantages of the effective field theory and causal approaches to quantum fi…
