Addressing the CKM unitarity problem with a vector-like up quark

Addressing the CKM unitarity problem with a vector-like up quark

Abstract We point out that hints of deviations from unitarity in the first row of the CKM matrix may be explained by the presence of a single vector-like top. We study how the stringent experimental constraints arising from CP Violation in the kaon sector and from meson mixing such as D 0 ‐ D ¯ 0 ,...
