Curls and curves of a shell interweave its various strain modes and link them together. This interactional behavior has yet frustrated all attempts for the construction of shell templates, which needs for an individual element test in traditional approaches. Such a test fails to work for shell elements and must be reconstructed. In this paper, it is tried to study shell interactional behavior a...

We determine the CKM matrix element |Vcb| using a sample of 3.33 million BB̄ events in the CLEO detector at CESR. We determine the yield of reconstructed B → D∗+lν decays as a function of w = vB · vD∗ , and from this we obtain the differential decay rate dΓ/dw. By extrapolating dΓ/dw to w = 1, the kinematic point at which the D is at rest relative to the B, we extract the product |Vcb|F (1), whe...

We have measured the fully inclusive K+ → μ+ν(γ) absolute branching ratio with the KLOE experiment at DAΦNE, the Frascati φ–factory. From some 865,283 K+ → μ+ν(γ) decays obtained from a sample of ∼5.2 × 108 φ-meson decays, we find BR(K+ → μνμ(γ))=0.6366±0.0009stat.±0.0015syst., corresponding to an overall fractional error of 0.27%. Using recent lattice results on the decay constants of pseudosc...

Using BABAR measurements of the inclusive electron spectrum in B → Xueν decays and the inclusive photon spectrum in B → Xsγ decays, we extract the magnitude of the CKM matrix element Vub. The extraction is based on several theoretical calculations designed to reduce the theoretical uncertainties by exploiting the assumption that the leading shape functions are the same for all b → q transitions...

We study Higgs production through weak boson fusion with subsequent decay to bottom quarks. By combining jet substructure techniques and matrix element methods in different limits we motivate this channel as a probe of the bottom-Yukawa interactions in the boosted regime. In particular we ameliorate the “no-go” results of cut-and-count analyses in this channel. After applying a data-driven reco...
