Webbdescription in the pionless EFT might indicate that the theory can be useful in studying larger nuclei. Since the pionless EFT makes no use of the QCD chiral symmetry, it cannot directly predict the quark mass dependence of observables. The parameters of the pionless EFT, at the lowest orders in the low-energy expansion, are the threshold ... Webb9 dec. 2012 · We use an effective field theory for short-range forces (SREFT) to analyze systems of three identical bosons interacting via a two-body potential that generates a scattering length, a, which is large compared to the range of the interaction, ℓ. The amplitude for the scattering of one boson off a bound state of the other two is computed … Webb1 juni 2024 · Proton–proton fusion in new pionless EFT po wer counting B. Behzadmoghaddam a , S.
