Hidden Symmetry and Georgi's Vector Limit
H. B. O'Connell, A. G. Williams
We study the generation of vector meson masses in the Hidden Local Symmetry (HLS) model of low energy QCD. After demoting the HLS to a hidden global symmetry (HGS), the rho is expl…

Near-threshold Isospin Violation in the Pion Form Factor from Chiral Perturbation Theory
H. B. O'Connell, K. Maltman, A. W. Thomas +1
We examine the isospin violation in the timelike pion form factor near threshold at next-to-leading order in the chiral expansion using the techniques of Chiral Perturbation Theory…
