More Synergies from Beauty, Top, $Z$ and Drell-Yan Measurements in SMEFT

Understand

We perform a global analysis of Beauty, Top, $Z$ and Drell-Yan measurements in the framework of the Standard Model effective theory (SMEFT).

• We work within the minimal flavor violation (MFV) hypothesis, which relates different sectors and generations beyond the $SU(2)_L$-link between left-handed top and beauty quarks.
• We find that the constraints on the SMEFT Wilson coefficients from the combined analysis are stronger than the constraints from a fit to the individual sectors, highlighting synergies in the global approach.
• We also show that constraints within MFV are strengthened compared to single-generation fits.
