Description

 

Precision studies of the Cabibbo-Kobayashi-Maskawa (CKM) matrix provide
a critical test of the Standard Model (SM). In this talk, I will review
the status of the Unitarity Triangle as a key tool for stress-testing
the SM in light of recent inputs and measurements for CKM metrology. I
will discuss the stringent constraints on New Physics derived from the
generalized ∣ΔF∣=2 effective Hamiltonian and their implications for
physics beyond the SM (BSM). Given these constraints and the ongoing
direct searches at the Large Hadron Collider (LHC), I will then
introduce Spontaneous Flavor Violation as a complementary framework to
Minimal Flavor Violation for BSM physics. Using a Two Higgs Doublet
Model as an example, I will demonstrate how a "charming" Higgs could be
observed at the LHC while still respecting the strong bounds from Flavor
Physics. In this charming regime, new Higgs states near the electroweak
scale with large couplings to quarks are predicted, offering
complementary observables and new insights into the measurement of
Yukawa couplings at colliders.
