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…
Leading Logarithms of the Two Point Function in Massless O(N) and SU(N) Models to any Order from Analyticity and Unitarity
B. Ananthanarayan, Shayan Ghosh, Alexey Vladimirov +1
Leading (large) logarithms in non-renormalizable theories have been investigated in the recent past. Besides some general considerations, explicit results for the expansion coeffic…
