This review article discusses the most important Physics thus far extracted from studies of B meson decays. We also point out where CP-violating and rare decays could lead to observations of physics beyond that of the Standard Model. If such physics is found by directly observation of new particles, e.g. in LHC experiments, B decays can play a decisive role in interpreting the nature of these particles.

In this paper, the Feynman path integral formulation of the continuous-continuous filtering problem, a fundamental problem of applied science, is investigated for the case when the noise in the signal and measurement model is Gaussian and additive. It is shown that it leads to an independent and self-contained analysis and solution of the problem.
