Pion Generalized Dipole Polarizabilities by Virtual Compton Scattering $π e \to π e γ$

C. Unkmeir, A. Ocherashvili, T. Fuchs +2

We present a calculation of the cross section and the event generator of the reaction $π e \to π e γ$ . This reaction is sensitive to the pion generalized dipole polarizabilities, name…

Generalized dipole polarizabilities and the spatial structure of hadrons

A. I. L'vov, S. Scherer, B. Pasquini +2

We present a phenomenological discussion of spin-independent, generalized dipole polarizabilities of hadrons entering the virtual Compton scattering process gamma* h -> gamma h. We…

Charged radiative pion capture on the nucleon in heavy baryon chiral perturbation theory

Harold W. Fearing, Thomas R. Hemmert, Randy Lewis +1

The differential cross sections and s-wave and p-wave multipoles for $π^{-} p \to γ n$ and $π^{+} n \to γ p$ have been calculated through $O (p^{3})$ in heavy baryon chiral perturbation the…

Radiative pion capture by a nucleon

Harold W. Fearing, Thomas R. Hemmert, Randy Lewis +1

The differential cross sections for $π^{-} p \to γ n$ and $π^{+} n \to γ p$ are computed up to $O (p^{3})$ in heavy baryon chiral perturbation theory (HBChPT). The expressions at $O (p)$ and…

Generalized polarizabilities of the pion in chiral perturbation theory

C. Unkmeir, S. Scherer, A. I. L'vov +1

We present a calculation of the virtual Compton scattering amplitude for $γ^{*} + π \to γ + π$ in the framework of chiral perturbation theory at $O (p^{4})$ . We explicitly derive e…
