Resumen
We have witnessed some flavor anomalies appearing in the past years, and explanations based on
extended gauge sectors are among the most popular solutions. These beyond the Standard Model (SM)
theories often assume flavor-changing interactions mediated by new vector bosons. Still, at the same
time, they could yield deviations from the SM in the K0 − K¯ 0, D0 − D¯ 0, B0

d, and B0
s − B¯ 0

systems. Using up-to-date data on the mass difference of these meson systems, we derive lower mass
bounds on vector mediators for two different parametrizations of the quark mixing matrices. Focusing on a
well-motivated model based on the fundamental representation of the weak SU(3) gauge group, we put our
findings into perspective with current and future hadron colliders to conclude that meson mass systems can
give rise to bounds much more stringent than those from high-energy colliders and that recent new physics
interpretations of the b → s and RðD Þ anomalies are disfavored
