  1. ; (, Physical Review C)
    We make order-by-order predictions of neutron–deuteron total cross sections up to next-to-next- to-leading order in pionless effective field theory. Using Bayesian methods, we infer a posterior distribution for the breakdown scale. The result shows a mode near 100 MeV, and a combined analysis with neutron–proton scattering further sharpens the inference, placing the mode close to the pion mass scale, consistent with the expected range of pionless effective field theory.vailable

    We use Bayesian statistics to infer the breakdown scale of pionless effective field theory in its standard power counting and with renormalization of observables carried out using the power-divergence subtraction scheme and cutoff regularization. We condition our inference on predictions of the total neutron-proton scattering cross section up next-to-next-to leading order. We quantify a median breakdown scale of approximately 1.4 mpi . The 68% degree of belief interval is [0.96, 1.69]mpi . This result confirms the canonical expectation that the pion mass is a relevant scale in low-energy nuclear physics.
