Asymptotic limits and the structure of the pion form factor
Dispersion technology solve meson chiral perturbation theory high energy low energy limit
font style='font-size:12px;'>
2014/12/22
We use dispersive techniques to address the behavior of the pion form factor as Q2 → ∞ and Q2 → 0. We perform the matching with the constraints of perturbative QCD and chiral perturbation theory in th...
Factorization in graviton scattering and the "natural" value of the g factor
Graviton scattering amplitude gyromagnetic ratio independent of the rotation
font style='font-size:12px;'>
2014/12/20
The factorization property of graviton scattering amplitudes is reviewed and show to be valid only if the "natural" value of the gyromagnetic ratio $g_S=2$ is employed -- independent of spin.
