Description
In particle physics, a theory called Standard Model has
been established in the last two decades, which successfully
describes almost all the known experimental results up
to O(100) GeV energy scale. However it is widely believed
that the Standard Model is only an approximation of an
unrevealed theory that governs physics at O(1000) GeV
energy scale, and purposes of the modern high energy physics
experiments are to search for and elucidate the new physics.
Among several possible approaches to this, flavor physics
challenges the new physics through high precision
measurements of decays of B mesons, D mesons, tau
leptons and so on, which provide complementary informations
to the experiments at energy frontier experiments such as
the
ones at LHC. In this talk, I will describe the quantitative
confirmation
of Kobayashi-Maskawa scheme of quark mixing and CP violation
in B Factory experiments, and describe the upgrade
program of the B factory at KEK to challenge the new physics
from
the studies of flavor physics.
