In this work, I suggest a new way for determining the CKM angle γ via B decays into a scalar/tensor meson without any hadronic uncertainty. The proposed idea makes profits of the two triangles formed by the [formula] (1430) decay amplitudes. The advantages in it are large CP asymmetries and the avoidance of the use of doubly Cabibbo-suppressed D decays. Branching ratios of [formula] (1430) are estimated to have the order 10-6 - 10-5 and therefore measurable on the ongoing LHCb experiment and future experimental facilities. The usefulness of other related channels, for instance the neutral Bd decays into DK*0(2) (1430) and Bs→(D0,D0)M(M = f0(980),f0(1370),f′2(1525),f1(1285),f1(1420),h1(1180)), the B→D∓a0,2± for the extraction of γ + 2β and the Bs→D∓K*0,2± to access γ + 2βs, is also discussed in brevity.

    We propose a new explanation for the dilepton excess observed in dense (hot) nuclear matter at invariant masses below 1GeV. We argue that the presence of local parity breaking due to a time-dependent isosinglet and/or isotriplet pseudoscalar condensate may substantially modify the dispersion...
