New results on radiative K± decays from the NA48/2 experiment are presented. In the channel K± → π±π0γ more than 1 million decays were reconstructed, leading to the first measurement of the interference between direct photon emission and inner bremsstrahlung and stringent limits on CP violation in this decay. For K → πγγ , a precise measurement of the branching fraction was performed, based on ...

We calculate D+ s → φ transition form factors V , A0, A1 and A2, and study semileptonic decay of D+ s → φl̄ν based on QCD sum rule method. We compare our results of the ratios of V (0)/A1(0), A2(0)/A1(0), ΓL/ΓT , and the total decay branching ratio of D+ s → φl̄ν with experimental data, and find that they are consistent.

In this paper we show that on a general hypersurface of degree r = 3, 4, 5, 6 in P 5 a rank 2 vector bundle E splits if and only if h 1 E(n) = h 2 E(n) = 0 for all n ∈ Z. Similar results for r = 1, 2 were obtained in [15], [16] and [1].
