Combining measurements of the lifetime with measurements of (angular) correlation parameters in neutron beta decay, we strive to most precisely determine the matrix element $V_\mathrm{ud}$ of the CKM quark mixing matrix. The goal is to test CKM unitarity on the $10^{-4}$ level.
Alternatively, combining the determination of $V_\mathrm{ud}$ from superallowed nuclear decays and neutron...
