Some Remarks on the Padé Unitarization of Low-Energy Amplitudes
We present a critical analysis of Padé-based methods for the unitarization of low energy amplitudes. We show that the use of certain Padé Approximants to describe the resonance region may lead to inaccurate determinations. In particular, we find that in the Linear Sigma Model the unitarization of the low energy amplitude through the inverse amplitude method produces essentially incorrect result...
متن کاملγ-γ Scattering: Saturation and Unitarization in the BFKL Approach
In this paper γ∗ − γ∗ scattering with large, but more or less equal virtualities of two photons is discussed using BFKL dynamics, emphasizing the large impact parameter behavior (bt) of the dipole-dipole amplitude. It is shown that the non-perturbative contribution is essential to fulfill the unitarity constraints in the region of bt > 1/2mπ , where mπ is pion mass. The saturation and the unita...
متن کاملLow energy Skyrmion-Skyrmion scattering.
We study the scattering of two Skyrmions at low energy and large separation. We use the method proposed by Manton for truncating the degrees of freedom of the system from in nite to a manageable nite number. This corresponds to identifying the manifold consisting of the union of the low energy critical points of the potential along with the gradient ow curves joining these together and by posit...
متن کاملLow-energy pion-nucleon scattering
An analysis of low-energy charged pion-nucleon data from recent pp experiments is presented. From the scattering lengths and the Goldberger-Miyazawa-Oehme ~GMO! sum rule we find a value of the pion-nucleon coupling constant of f 50.075660.0007. We also find, contrary to most previous analyses, that the scattering volumes for the P31 and P13 partial waves are equal, within errors, corresponding ...
متن کاملLow Energy Compton Scattering and Nucleon Structure
The low energy virtual Compton scattering process eN → eNγ offers a new and potentially high resolution window on nucleon structure via measurement of so-called generalized polarizabilities (GPs). We present calculations of GPs within heavy baryon chiral perturbation theory and discuss present experimental efforts.
