The PCAC Puzzle for the Nucleon Axial and Pseudoscalar Form Factors - Sara Collins

Explore the PCAC puzzle for nucleon axial and pseudoscalar form factors in this conference talk by Sara Collins from the University of Regensburg. Delve into the interdisciplinary developments in neutrino physics, focusing on maximizing new physics potential, understanding high-precision neutrino cross sections, and addressing the impact of neutrinos on astrophysical and cosmological processes. Examine topics such as the PCAC relation, isospin limit, induced pseudoscalar, excited state contributions, effective field theory, and limitations of various analytical approaches. Gain insights into the control of the mass plane, baryon mass spectrum, and axial form factor GA as part of the Interdisciplinary Developments in Neutrino Physics Conference organized by the Kavli Institute for Theoretical Physics.
