On a realization of {β}-expansion in QCD
Journal of High Energy Physics, 2017 We suggest a simple algebraic approach to fix the elements of the {β}-expansion for renormalization group invariant quantities, which uses additional degrees of freedom.

Renormalized measure of regular languages [PDF]
International Journal of Control, 2006 This paper modifies the signed real measure of regular languages, which has been reported in recent literature for analysis and synthesis of discrete event supervisory control laws. A new concept of renormalized measure is introduced to eliminate a user-selectable parameter in the present version of the language ...

Multi-collinear splitting kernels for track function evolution
Journal of High Energy Physics, 2023 Jets and their substructure play a central role in many analyses at the Large Hadron Collider (LHC). To improve the precision of measurements, as well as to enable measurement of jet substructure at increasingly small angular scales, tracking information

Renormalization of the classical massless scalar field theory with quartic self-interaction [PDF]
, 2013 The classical theory of the massless scalar field with negative quartic selfinteraction shows asymptotic freedom and confinement. These findings might help in understanding evidence, gathered from experiment and lattice simulations of quantum ...

Line defect RG flows in the ε expansion
Journal of High Energy Physics, 2023 A general analysis of line defect renormalisation group (RG) flows in the ε expansion below d = 4 dimensions is undertaken. The defect beta function for general scalar-fermion bulk theories is computed to next-to-leading order in the bulk couplings ...

Renormalization Using Domain Wall Regularization [PDF]
Progress of Theoretical Physics, 2002 We formulate the renormalization procedure using the domain wall regularization that is based on the heat-kernel method. The quantum effects of both fermions and bosons (gauge fields) are taken into account. The background field method is quite naturally introduced.

Physics Letters B, 2017 At the three-loop level we analyze, how the NSVZ relation appears for N=1 SQED regularized by the dimensional reduction. This is done by the method analogous to the one which was earlier used for the theories regularized by higher derivatives. Within the

One-loop diagrams with quadratic propagators from the worldsheet
Journal of High Energy Physics, 2022 It is well known that forward limits of tree-level amplitudes (and those trivalent diagrams they consist of) produce one-loop amplitudes and trivalent diagrams with propagators linear in the loop momentum.

Manifestly N=2 supersymmetric regularization for N=2 supersymmetric field theories
Physics Letters B, 2015 We formulate the higher covariant derivative regularization for N=2 supersymmetric gauge theories in N=2 harmonic superspace. This regularization is constructed by adding the N=2 supersymmetric higher derivative term to the classical action and inserting

Scalar-fermion fixed points in the ε expansion
Journal of High Energy Physics, 2023 The one-loop beta functions for systems of N s scalars and N f fermions interacting via a general potential are analysed as tensorial equations in 4 − ε dimensions.
