Good Agreement

The NA48/2 experiment presents preliminary measurements of the form factors of the charged kaon semileptonic decays. The Ke3 and Kμ3 results are in good agreement allowing for a combined result which matches the precision of the current world average on the vector and scalar form factors. Recent study of the rare decay K± → π±γγ from the NA48/2 and NA62 data samples is also reported.

The Continuum

The semileptonicBs(B)→K2⁎(a2,f2)lν,l=τ,μ, transitions are investigated in the frame work of the three-point QCD sum rules. Considering the quark condensate contributions, the relevant form factors of these transitions are estimated. The branching ratios of these channel modes are also calculated at different values of the continuum thresholds of the tensor mesons and compared with the obtained data for other approaches.

The inserting of antisymmetric tensor fields into the standard electroweak theory may explain the recent experiments on [Formula: see text] and K+ → πoe+ν decays. New intermediate particles can induce the destructive interference in the pion decay and the nonzero tensor and scalar form factors in the kaon decay.
