In this paper, the authors presented the partial branching fraction for inclusive charmless semileptonic B decays and the corresponding value of the Cabibbo-Kobayashi-Maskawa matrix element |Vub|, using a multivariate analysis method to access ∼90% of the B→Xu ν phase space.Abstract:
We present the partial branching fraction for inclusive charmless semileptonic B decays and the corresponding value of the Cabibbo-Kobayashi- Maskawa matrix element |Vub|, using a multivariate analysis method to access ∼90% of the B→Xu ν phase space. This approach dramatically reduces the theoretical uncertainties from the b-quark mass and nonperturbative QCD compared to all previous inclusive measurements. The results are based on a sample of 657×106 BB pairs collected with the Belle detector. We find that ΔB(B→Xu ν;p *B>1.0GeV/c)=1. 963×(1±0.088stat±0.081syst)×10-3. Corresponding values of |Vub| are extracted using several theoretical calculations. © 2010 The American Physical Society.read more

TL;DR: In this paper, the progress, current status, and open challenges of QCD-driven physics, in theory and in experiment, are highlighted, highlighting how the strong interaction is intimately connected to a broad sweep of physical problems, in settings ranging from astrophysics and cosmology to strongly coupled, complex systems in particle and condensed-matter physics, as well as searches for physics beyond the Standard Model.

CP Violation in the Renormalizable Theory of Weak Interaction
TL;DR: In this article, it was shown that no CP-violating interactions exist in the quartet scheme without introducing any other new fields, and that the strong interaction must be chiral SU ( 4) X SU( 4) invariant as precisely as the conservation of the third component of the iso-spin.
