Form factors of the meson from effective field theory and the lattice
Ulf-G. MeiÃner, Akaki Rusetsky, Ajay S. Sakthivasan +2
The calculation of resonance form factors in effective field theory as well as on the lattice is a highly challenging task. In a recent paper, we proposed a novel method based on t…

Neutrinoless double-beta decay of the resonance
Li-Ping He, Feng-Kun Guo, Ulf-G. MeiÃner +3
The subprocess is a key ingredient in the interpretation of nuclear neutrinoless double-beta decay. Intermediate resonances may provide additional enhancement…

Lattice QCD Study of Pion Electroproduction and Weak Production from a Nucleon
Yu-Sheng Gao, Zhao-Long Zhang, Xu Feng +3
Quantum fluctuations in QCD influence nucleon structure and interactions, with pion production serving as a key probe of chiral dynamics. In this study, we present a lattice QCD ca…
