The authors record the contribution of dentistry to the identification of victims of one of the most significant tragedies of the 20th century—the mass suicide of members of a religious cult, which initially resulted in 913 deaths and ultimately in 923. Though forensic dentistry played a significant part in identifying victims, the only report by members of the United States identification team...

Extracting γ from Bs(d) → J/ψ KS and Bd(s) → D + − d(s) Dd(s)

A completely general parametrization of the time-dependent decay rates of the modes B s → J/ψ K S and B d → J/ψ K S is given, which are related to each other through the U-spin flavour symmetry of strong interactions. Owing to the interference of current–current and penguin processes, the B s → J/ψ K S observables probe the angle γ of the unitarity triangle. Using the U-spin symmetry, the overa...

Leptonic D and D s Decays near cc̄ Threshold

Within the Standard Model, leptonic D (or B) meson decays proceed via annihilation of the initial state quarks. The matrix element is described by the product of a hadronic current, a leptonic current, along with a W propagator. The form of the latter two are well-known within the Standard Model, however, the hadronic matrix element, which represents the annihilation of the initial state heavy ...

M ay 2 00 1 Analysis of direct CP violation in B − → D 0 D − s , D 0 D − decays

We investigate the possibility of observing the direct CP violation in the decay modes B → D0D− s and D0D− within the Standard Model. Including the contributions arising from the tree, annihilation, QCD as well as electroweak penguins with both timeand space-like components, we find that the direct CP asymmetry in B → D0D− s is very small ∼ 0.2 % but in B → D0D− decay it can be as large as 4%. ...
