Measurement of the Proton Asymmetry Parameter in Neutron Beta Decay

Year: 2008

Type: article

Abstract: The proton asymmetry parameter C in neutron decay describes the angular correlation between neutron spin and proton momentum. In this Letter, the first measurement of this quantity is presented. The result C= -0.2377(26) agrees with the standard model expectation. The coefficient C provides an additional parameter for new and improved standard model tests.
