A New Theory Framework for the Electroweak Radiative Corrections in Decays
Chien-Yeah Seng, Daniel Galviz, Ulf-G. Meißner
We propose a new theory framework to study the electroweak radiative corrections in decays by combining the classic current algebra approach with the modern effective fiel…
Reduced uncertainty of the axial -box correction to the proton's weak charge
Jens Erler, Mikhail Gorchtein, Oleksandr Koshchii +2
We present the fully up-to-date calculation of the -box correction which needs to be taken into account to determine the weak mixing angle at low energies from parity-violating…
Toward a First-Principles Calculation of Electroweak Box Diagrams
Chien-Yeah Seng, Ulf-G. Meißner
We derive a Feynman-Hellmann theorem relating the second-order nucleon energy shift resulting from the introduction of periodic source terms of electromagnetic and isovector axial…
Constraints on Disconnected Contributions in Scattering
N. Ripunjay Acharya, Feng-Kun Guo, Ulf-G. Meißner +1
The accuracy of the lattice QCD computation of hadron-hadron scattering at low isospin depends critically on the ability to compute correlation functions with fermionic disconnecte…
