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…
New analytic continuations for the Appell series from quadratic transformations of the Gauss function
B. Ananthanarayan, Samuel Friot, Shayan Ghosh +1
We present new analytic continuation formulas for the Appell double hypergeometric series where , which allows quadratic transformations of the Gauss ${…
The three-loop QED contributions to the of charged leptons with two internal fermion loops and a class of Kampé de Fériet series
B. Ananthanarayan, Samuel Friot, Shayan Ghosh
The three-loop QED mass-dependent contributions to the of each of the charged leptons with two internal closed fermion loops, sometimes called $A^{(6)}_3\left(\frac{m_1}{m_2}…
New Series Representations for the Two-Loop Massive Sunset Diagram
B. Ananthanarayan, Samuel Friot, Shayan Ghosh
We derive new convergent series representations for the two-loop sunset diagram with three different propagator masses m1, m2 and m3 and external momentum p by techniques of analyt…
Pion Interactions and the Standard Model at High Precision
B. Ananthanarayan, Shayan Ghosh
Pions were predicted by H. Yukawa as force carriers of the inter-nucleon forces, and were detected in 1947. Today they are known to be bound states of quarks and anti-quarks of the…
Analytic representations of , , and in two loop chiral perturbation theory
B. Ananthanarayan, Johan Bijnens, Samuel Friot +1
In this work, we consider expressions for the masses and decay constants of the pseudoscalar mesons in chiral perturbation theory. These involve sunset diagrams and their d…
