Rearranging pionless effective field theory
WebbPDF - We point out a redundancy in the operator structure of the pionless effective field theory, EFT(π), which dramatically simplifies computations. This redundancy is best … WebbWe show proper renormalization of our calculation analyzing the residual cutoff dependence of observables. We find that next-to-leading order corrections contribute about $4\%$ to the triton decay Gamow-Teller strength. We show that these conclusions are insensitive to different arrangements of the effective range expansion.
