Abstract:We have recently completed a high-precision extraction of the proton spin-independent polarisabilities from the world database of low-energy Compton scattering experiments, within the framework of chiral effective field theory (χEFT) with pions, nucleons, and the Delta(1232) as explicit degrees of freedom. Our Baldin-sum-rule-constrained results are, in units of 10 −4 fm 3 ,These were obtained in the heavy-baryon formulation, but almost identical results have been obtained in a covariant calculation. With the … Show more
