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…
Solar fusion III: New data and theory for hydrogen-burning stars
B. Acharya, M. Aliotta, A. B. Balantekin +47
In stars that lie on the main sequence in the Hertzsprung-Russel diagram, like our sun, hydrogen is fused to helium in a number of nuclear reaction chains and series, such as the p…
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…
