Abstract We point out that testing the equality of the Cabibbo angle as extracted from Γ(K → πlν), the ratio Γ(K → lν)/Γ(π → lν) and nuclear β decays is not identical to a test of first row unitarity of the Cabibbo-Kobayashi-Maskawa (C

Abstract We present in a full analytic form the partial widths for the lepton flavour violating decays $$\mu ^{\pm } \rightarrow e^{\pm } e^+ e^-$$ μ±→e±e+e- and $$\tau ^{\pm } \rightarrow \ell ^{\pm } \ell '^{+} \ell '^{-}$$ τ±→ℓ±ℓ′+

Abstract The dispersive analysis of the decay $$\eta \rightarrow 3\pi $$ η→3π is reviewed and thoroughly updated with the aim of determining the quark mass ratio $$Q^2=(m_s^2-m_{ud}^2)/(m_d^2-m_u^2)$$ Q2=(ms2-mud2)/(md2-mu2) . With the number of

Abstract We study the hadronic $$\eta ^{\prime }\rightarrow \eta \pi \pi $$ η′→ηππ decays within the framework of $$U(3)_{L}\otimes U(3)_{R}$$ U(3)L⊗U(3)R Chiral Perturbation Theory including resonance states and the complete one-loop corre

We study the transition widths of $\Upsilon(10753)$ and $\Upsilon(11020)$ into standard bottomonium under the hypothesis that they correspond to the two lowest laying $1^{--}$ hybrid bottomonium states. We employ weakly coupled potential NRQCD an eff

Kℓ₄ decays have several features of interest: they allow an accurate measurement of ππ -scattering lengths; the decay is the best source for the determination of some low-energy constants of chiral perturbation theory (χPT); one form factor of
