Extracting the low-energy constant at three flavors from pion-kaon scattering
Chaitra Kalmahalli Guruswamy, Ulf-G. Meißner, Chien-Yeah Seng
Based on our analysis of the contributions from the connected and disconnected contraction diagrams to the pion-kaon scattering amplitude, we provide the first determination of the…

Contraction Diagram Analysis in Pion-Kaon Scattering
Chaitra Kalmahalli Guruswamy, Ulf-G. Meißner, Chien-Yeah Seng
We study the contributions from the connected and disconnected contraction diagrams to the pion-kaon scattering amplitude within the framework of SU partially-quenched chira…
