On a two-loop crossed six-line master integral with two massive lines
- Mathematics
- 2009
We compute the two-loop crossed six-line vertex master integral with two massive lines in dimensional regularisation, and give the result up to the finite part in D−4. We apply the differential…
Effective potential at three loops
- Physics

I present the effective potential at three-loop order for a general renormalizable theory, using the \MSbar renormalization scheme and Landau gauge fixing. As applications and illustrative points of…
Evaluation of the general three-loop vacuum Feynman integral
- Computer Science
- 2017
A set of modified finite basis integrals that are particularly convenient for expressing renormalized quantities are defined that can be computed numerically by solving coupled first-order differential equations, using as boundary conditions the analytically known special cases that depend on only one mass scale.

-finite master integrals and their virtues: The three-loop self-energy case
- PhysicsPhysical Review D
- 2022
Loop diagram calculations typically rely on reduction to a finite set of master integrals in 4− 2ǫ dimensions. It has been shown that for any problem, the masters can be chosen so that their…
Standard model parameters in the tadpole-free pure

- PhysicsPhysical Review D

We present an implementation and numerical study of the Standard Model couplings, masses, and vacuum expectation value (VEV), using the pure $\overline{\rm{MS}}$ renormalization scheme based on…
Multiple (inverse) binomial sums of arbitrary weight and depth and the all-order ε-expansion of generalized hypergeometric functions with one half-integer value of parameter
- Mathematics
- 2007
We continue the study of the construction of analytical coefficients of the ?-expansion of hypergeometric functions and their connection with Feynman diagrams. In this paper, we show the following…
Hypergeometric Functions and Feynman Diagrams
- MathematicsTexts & Monographs in Symbolic Computation
- 2021
The relationship between Feynman diagrams and hypergeometric functions is discussed. Special attention is devoted to existing techniques for the constructionof the Y-expansion. As an example, we…
Subleading power resummation of rapidity logarithms: the energy-energy correlator in $$ \mathcal{N} $$ = 4 SYM
- Physics
- 2019
We derive and solve renormalization group equations that allow for the resummation of subleading power rapidity logarithms. Our equations involve operator mixing into a new class of operators, which…
