Introduction
Flavour and CPV in the Standard Model
The history of the UT since ∼ 1993
The history of the UT since ∼ 1993
Situation in 1993:
HQET was still young (∼ 3 years)
Hadronic Matrix elements for
∆m d ∼ fB 2 were quite uncertain
V ub /V cb was known at the level of ∼ 20%
The top quark mass was still m t ∼ (140 ± 40) GeV
No CP violation has been observed except ɛ K
The UT still could have been “flat”
