We obtain a large class of smooth Lorentzian p-brane wormholes in supergravities in various dimensions. They connect two asymptotically flat spacetimes. In cases where there is no dilaton involved in the solution, the wormhole can connect an AdSn × Sm in one asymptotic region to a flat spacetime in the other. We obtain explicit examples for (n,m) = (4, 7), (7, 4), (5, 5), (3, 3), (3, 2). These ...

The decays of Υ(1s) → γ(η, η) are studied by an approach which has successfully predicted the ratio Γ(J/ψ→γη ) Γ(J/ψ→γη) . Strong dependence on quark mass has been found in the decays (J/ψ,Υ(1s)) → γ(η, η). Very small decay rates of Υ(1s) → γ(η, η) are
