The ratio of partial decay rates for charged and neutral B mesons to Kπ final states provides information on the weak phase γ ≡ Arg(V ∗ ub) when augmented with information on the CP-violating asymmetry in the Kπ mode. The statistical requirements for a useful determination of γ and certain systematic uncertainties are examined in the light of present information about the decays B → Kπ, B → Kπ,...
We calculate the inclusive charmless semileptonic decay width of the B meson using a QCD-based approach. This approach is able to account for both dynamic and kinematic effects of nonperturbative QCD. The charmless semileptonic decay width is found to be enhanced by long-distance strong interactions by +(7± 5)% with respect to the free quark decay width. Using the resulting theoretical value fo...
In this study, the seismic interaction of surface foundations and underground cavities was investigated. For this purpose, a parametric study of geometric dimensions of the foundation and cavity, their location, and the effect of the interaction between surface foundations and underground cavities was evaluated. The variable parameters include the ratio of the overburden height to the foundatio...
