Massive One-loop Conformal Feynman Integrals and Quadratic Transformations of Multiple Hypergeometric Series
B. Ananthanarayan, Sumit Banik, Samuel Friot +1
The computational technique of -fold Mellin-Barnes (MB) integrals, presented in a companion paper by the same authors, is used to derive sets of series representations of the ma…
Multiple Series Representations of -fold Mellin-Barnes Integrals
B. Ananthanarayan, Sumit Banik, Samuel Friot +1
Mellin-Barnes (MB) integrals are well-known objects appearing in many branches of mathematics and physics, ranging from hypergeometric functions theory to quantum field theory, sol…
The Double Box and Hexagon Conformal Feynman Integrals
B. Ananthanarayan, Sumit Banik, Samuel Friot +1
The off-shell massless six-point double box and hexagon conformal Feynman integrals with generic propagator powers are expressed in terms of linear combinations of multiple hyperge…
Quadratic and quartic integrals using the method of brackets
B Ananthanarayan, Sumit Banik, Sudeepan Datta +1
We use the method of brackets to evaluate quadratic and quartic type integrals. We recall the operational rules of the method and give examples to illustrate its working. The metho…
