Muon Capture on the Proton with Heavy-Light Currents

Evan Combes, Emanuele Mereghetti, Lucas Platter

We construct a non-relativistic Lagrangian that describes muon-proton electroweak interactions. We determine the leading order coefficients by matching onto the theory with non-rel…

Taming nuclear size and shape effects in superallowed beta-decay

Bingcheng He, Mikhail Gorchtein, Matthias Heinz +3

We present the first combined analysis of the statistical rate function f in superallowed beta decays with ab initio calculations and data. We focus on C10 to 10B, 14O to 14N and 2…

Inferring the breakdown scales of the chiral expansions for and

Andreas Ekström, Daniel R. Phillips, Lucas Platter +1

We apply Bayesian inference to the order-by-order chiral perturbation theory (PT) expansions for the axial-vector coupling constant and the nucleon mass m_N, and thereby i…

Improved nuclear-structure corrections to the hyperfine splitting of electronic and muonic deuterium

Jose Bonilla, Thomas R. Richardson, Sonia Bacca +2

We calculate the nuclear-structure correction to the hyperfine splitting in both electronic and muonic deuterium using interactions from chiral effective field theory. We explore t…

Non-Efimovian two-neutron halos with an -wave core-neutron resonance

Lucas Platter, Dam Thanh Son

We consider two-neutron halo nuclei in which the neutron core subsystem displays a resonance close to threshold. Such resonances can be generated in an effective field theory in wh…

The breakdown scale of pionless effective field theory in the three-nucleon sector

Andreas Ekström, Lucas Platter

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…
