To this order, we present the systematic evaluation of all the corrections due to the QED and electroweak radiative corrections and the proton-size effect. Since the low-energy constants involved can be determined from other independent sources of information, the theory has predictive power. For the hyperfine-singlet $\\mu p$ capture rate $\\Gamma_0$, our calculation gives $\\Gamma_0=710 \\,\\pm 5\\,s^{-1}$, which is in excellent agreement with the experi","authors_text":"F. Myhrer, K.
