DISPERSION-RELATIONS AND THE NUCLEON POLARIZABILITY
Protons and neutrons polarizability dispersion relations meson polarizability

Recent experimental results on the proton and neutron polarizabilities are examined from the point of view of backward dispersion relations. Results are found to be in reasonable agreement with the me...
On the Marriage of Chiral Perturbation Theory and Dispersion Relations
Dispersion relations chiral perturbation theory gw PI
2014/12/23
I describe the methodology for the use of dispersion relations in connection with chiral perturbation theory. The conditions for matching the two formalisms are given at $O(E^2)$ and $O(E^4)$. The two...
The techniques of dispersion relations match very well with those of effective field theory. I describe the techniques for using dispersion relations effectively, and give some pedagogical examples to...
