Abstract
We report on a search for flavor-changing neutral-currents (FCNC) in the production of heavy quarks in deep inelastic νμN and ν¯μN scattering by the NuTeV experiment at the Fermilab Tevatron. This measurement, made possible by the high-purity NuTeV sign-selected beams, probes for FCNC in heavy flavors at the quark level, and is uniquely sensitive to neutrino couplings of potential FCNC mediators. All searches are consistent with zero, and limits on the effective mixing strengths |Vuc|2, |Vdb|2, and |Vsb|2 are obtained.Received 31 July 2000DOI:https://doi.org/10.1103/PhysRevD.63.012001©2000 American Physical Society
