CP violation in B decays and final state strong phases
Fayyazuddin
Using the unitarity, SU(2) and C invariance of hadronic interactions, the bounds on final state phases are derived. It is shown that values obtained for the final state phases relevant for the direct CP asymmetries A(B-->Kpi,Kpi) are compatible with experimental values for these asymmetries. For the ... [Phys.

Correlation classes on the landscape: To what extent is string theory predictive?
Keith R. Dienes and Michael Lennek
In light of recent discussions of the string landscape, it is essential to understand the degree to which string theory is predictive. We argue that it is unlikely that the landscape as a whole will exhibit unique correlations amongst low-energy observables, but rather that different regions of the ... [Phys. Rev.
