Pion–pion scattering at low energy
We present technical details of the evaluation of the elastic ππ scattering amplitude to two loops in chiral perturbation theory. In particular, we elaborate on the renormalization procedure at the two–loop order and on the evaluation of the relevant Feynman diagrams that can all be expressed in terms of elementary functions. For the sake of clarity, we discuss these matters both in the N–compo...
متن کاملLow energy spectral and scattering theory for relativistic Schrödinger operators
Spectral and scattering theory at low energy for the relativistic Schrödinger operator are investigated. Some striking properties at thresholds of this operator are exhibited, as for example the absence of 0-energy resonance. Low energy behavior of the wave operators and of the scattering operator are studied, and stationary expressions in terms of generalized eigenfunctions are proved for the ...
متن کاملLow energy proton-proton scattering in effective field theory
Low energy proton-proton scattering is studied in pionless effective field theory. Employing the dimensional regularization and MS and power divergence subtraction schemes for loop calculation, we calculate the scattering amplitude in S0 channel up to nextto-next-to leading order and fix low-energy constants that appear in the amplitude by effective range parameters. We study regularization sch...
متن کاملVery low-energy electron scattering from benzene: experiment and theory
Low-energy collision studies have shown that the scattering cross section for electrons by benzene rises sharply at electron impact energies below∼ 200 meV. This was attributed in earlier work to electron attachment and formation of benzene anions with lifetimes τ 1μs. A detailed study of electron attachment to benzene is reported here that makes use of Rydberg atom techniques. The data provide...
