Nucleon Axial Form Factor in Some Bag Models

摘要

We compute gsub(A)(qsup(2)) for various bag models, including effects of an additional central force and recoil. For a confinement radius R approximately 0.85 fm predictions reproduce the data up to q < 0.5 fm, but fall faster than the observed dipole behaviour beyond. (Atomindex citation 15:060563)
