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…

Inferring the breakdown scales of the chiral expansions for $g_{A}$ and $m_{N}$

Andreas EkstrÃ¶m, Daniel R. Phillips, Lucas Platter +1

We apply Bayesian inference to the order-by-order chiral perturbation theory ( $I ¨ $ PT) expansions for the axial-vector coupling constant $g_{A}$ and the nucleon mass m_N, and thereby…
