Quantization of interacting Galilean field theories
Journal of High Energy Physics, 2022 We present the quantum field description of Galilean electrodynamics minimally coupled to massless Galilean fermion in (3 + 1)-dimensions. At classical level, the Lagrangian is obtained as a null reduction of a relativistic theory in one higher dimension.

Five-loop anomalous dimensions of ϕ Q operators in a scalar theory with O(N) symmetry
Journal of High Energy Physics, 2022 We compute the complete Q-dependence of anomalous dimensions of traceless symmetric tensor operator ϕ Q in O(N) scalar theory to five-loop. The renormalization factors are extracted from ϕ Q → Q ϕ form factors, and the integrand of form factors are ...

General scalar renormalisation group equations at three-loop order
Journal of High Energy Physics, 2020 For arbitrary scalar QFTs in four dimensions, renormalisation group equations of quartic and cubic interactions, mass terms, as well as field anomalous dimensions are computed at three-loop order in the MS ¯ $$ \overline{\mathrm{MS}} $$ scheme. Utilising

Regularized Renormalization Group Reduction of Symplectic Maps [PDF]
Journal of the Physical Society of Japan, 2001 By means of the perturbative renormalization group method, we study a long-time behaviour of some symplectic discrete maps near elliptic and hyperbolic fixed points. It is shown that a naive renormalization group (RG) map breaks the symplectic symmetry and fails to describe a long-time behaviour. In order to preserve the symplectic symmetry, we present

Renormalization in Wavelet basis
, 2023 Discrete wavelet-based methods promise to emerge as an excellent framework for the non-perturbative analysis of quantum field theories. In this work, we investigate aspects of renormalization in theories analyzed using wavelet-based methods.

Effective action for the Yukawa model in curved spacetime
Journal of High Energy Physics, 2018 We consider the one-loop renormalization of a real scalar field interacting with a Dirac spinor field in curved spacetime. A general Yukawa interaction is considered which includes both a scalar and a pseudoscalar coupling. The scalar field is assumed to

Dimensional regularization and renormalization of QED [PDF]
Communications in Mathematical Physics, 1990 The tree expansion method of renormalization [see e.g. \textit{G. Gallavotti}, Rev. Mod. Phys. 57, 471-562 (1985)] has been applied to QED by \textit{J. Feldman}, \textit{T. Hurd}, and the authors [QED: A proof of renormalizability. Lect. Notes Phys. 312 (1988)]. The purpose of the present paper is to replace the loop regularization used there, with an

Off-shell divergences in quantum gravity
Journal of High Energy Physics, 2023 We investigate off-shell perturbative renormalisation of pure quantum gravity for both background metric and quantum fluctuations. We show that at each new loop order, the divergences that do not vanish on-shell are constructed from only the total metric,
