Description:
We analyze the tauonic semileptonic baryon decays Λ0b→Λ+c+τ−+ν̄ τ with particular emphasis on the lepton helicity flip contributions which vanish for zero lepton masses. We calculate the total rate, d

Description:
We derive the lowest-order qq valence light-front wave function for the pion with Lz = 0 and |Lz| = 1, which reproduces its valence parton distribution and the electromagnetic form factor consistent w

Description:
The effect of isoscalar S-wave multichannel ππ→ππ, KK¯¯,ηη scattering is considered in the analysis of decay data of the Υ-mesons. We show that when allowing for the final state interaction contributi

Description:
Recently there has been much interest in the tauonic semileptonic meson decays B→D+τ+ντ and B→D∗+τ+ντ, where one has found larger rates than what is predicted by the Standard Model. We analyze the cor

Description:
We present a unified analysis of the decays of bottomonia Υ(mS)→Υ(nS)ππ (m>n, m=2,3,4,5, n=1,2,3), charmonia J/ψ→ϕ(ππ,KK¯), ψ(2S)→J/ψππ, and the isoscalar S-wave processes ππ→ππ,KK¯,ηη. In this analys
