Pion Cloud Contributions to the Proton's Weak Magnetic Form Factor
Simon Capstick, D. Robson
We report on the contributions to the nucleon weak magnetic and electric form factors arising from isospin-breaking form factors. The relativized quark model used in the calculatio…

Baryon Current Matrix Elements in a Relativistic Quark Model
Simon Capstick, B. D. Keister
Current matrix elements and observables for electro- and photo-excitation of baryons from the nucleon are studied in a light-front framework. Relativistic effects are examined by c…
