title = "Measurement of the muon capture rate in hydrogen gas and determination of the proton's pseudoscalar coupling gP",
abstract = "The rate of nuclear muon capture by the proton has been measured using a new technique based on a time projection chamber operating in ultraclean, deuterium-depleted hydrogen gas, which is key to avoiding uncertainties from muonic molecule formation. The capture rate from the hyperfine singlet ground state of the μp atom was obtained from the difference between the μ- disappearance rate in hydrogen and the world average for the μ+ decay rate, yielding ΛS=725.0±17.4s-1, from which the induced pseudoscalar coupling of the nucleon, gP(q2=-0.88mμ2)=7.3±1.1, is extracted.",
