We explore “weak” supersymmetric systems whose algebra involves, besides Poincare generators, extra bosonic generators not commuting with supercharges. This allows one to have inequal number of bosonic and fermionic 1–particle states in the spectrum. Coleman–Mandula and Haag–Lopuszanski–Sohnius theorems forbid the presence of such extra bosonic charges in interacting theory for d ≥ 3. However, ...

The current status of some methods to determine the weak phase γ of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element V ∗ ub using B decays is discussed, and comments are made on accuracy achievable in the next few years.
