Final state interactions in hadronic B decays
TL;DR: In this paper, the authors examined the final-state rescattering effects on the hadronic $B$ decay rates and their impact on direct CP violation and showed that the effect of rescattering on the CP violation is very small in the standard model even after the inclusion of FSIs.

TL;DR: In this paper, the authors analyze the Z c ( ′ ) → η c ρ decay using both approaches, and provide useful insights on the nature of Z c( ′ ), helping discriminating between the two different models.

Hidden beauty baryon states in the local hidden gauge approach with heavy quark spin symmetry
C. W. Xiao,Eulogi Oset +1 more
TL;DR: Using a coupled channel unitary approach, combining the heavy quark spin symmetry and the dynamics of the local hidden gauge, the authors investigated the meson-baryon interaction with hidden beauty and obtained several new states of N ∗ around 11 GeV.

QCD factorization for B ---> pi pi decays: Strong phases and CP violation in the heavy quark limit
TL;DR: In this article, it was shown that the hadronic matrix elements that enter B meson decays into two light mesons can be computed from first principles, including {open_quotes}nonfactorizable strong interaction corrections, and expressed in terms of form factors and meson light-cone distribution amplitudes.
