Form factors and photoproduction amplitudes

We examine the use of phenomenological form factors in tree level amplitudes for meson photoproduction. Two common recipes are shown to be fundamentally incorrect. An alternate form consistent with gauge invariance and crossing symmetry is proposed. PACS numbers: 25.20.Lj, 13.60.Le, 11.40.-q, 11.80.Cr Typeset using REVTEX [email protected] [email protected]

Neutral Pion Photoproduction in a Regge Model

The reaction γp → πp is investigated in the energy range above the resonance region. The amplitudes include the leading Regge singularities in the cross-channel and correctly describe the differential cross section for beam energies above 4 GeV and for momentum transferred above −3 GeV. The energy dependence of the beam asymmetry and the reaction γn → πn seem is quantitative consistent with the...

Form factors of pion and kaon

Besides the vector meson poles in the form factors of charged pion and kaons additional intrinsic form factors of pion and kaons are found. A detailed study of the form factors of pion and kaons in both time-like and space-like regions is presented. Theory agrees well with data up to q ∼ 1.4GeV . In this study there is no adjustable parameter.

Ππ Scattering and Pion Form Factors

The S and P wave ππ phase shifts are recalculated in terms of two phenomenological parameters using the one loop CPTh and the elastic unitarity condition. Using these phase shifts, the vector and scalar form factors are calculated and shown to be in a good agreement with experimental data. It is found that the simpler and more phenomenological approach, where the left hand cut contributions to ...

The Pion and Kaon Electromagnetic Form Factors

We use recent data on K + → π + e + e − , together with known values for the pion form factor, to derive the kaon electromagnetic form factor for 0 < q 2 < 0.125 (GeV/c) 2. The results are then compared with predictions of the Linear σ Model, a quark-triangle model and Vector Meson Dominance. The first two models describe the data at least qualitatively, but the simple Vector Meson Dominance pi...
