Semileptonic decays $Λ_{c}^{+} \to Λ ℓ^{+} ν_{ℓ} (ℓ = e, μ)$ in the covariant quark model and comparison with the new absolute branching fraction measurements of Belle and BESIII

Thomas Gutsche, Mikhail A. Ivanov, Jurgen G. Korner +2

We present precise theoretical predictions for the absolute branching fractions of $Λ_{c}^{+} \to Λ ℓ^{+} ν_{ℓ} (ℓ = e, μ)$ decays in the covariant confined quark model. This study i…

Physical observables in the decay $Λ_{b} \to Λ_{c} (\to Λ + π) + τ^{-} + ν ˉ_{τ}$

Nurgul Habyl, Thomas Gutsche, Mikhail A. Ivanov +3

We analyze the tauonic semileptonic baryon decays $Λ_{b}^{0} \to Λ_{c}^{+} + τ^{-} + ν ˉ_{τ}$ with particular emphasis on the lepton helicity flip contributions which vanish for zero lepto…

Exclusive decays $B \to ℓ^{-} ν ˉ$ and $B \to D^{(*)} ℓ^{-} ν ˉ$ in the covariant quark model

Mikhail A. Ivanov, Jürgen G. Körner, Chien-Thang Tran

We study the exclusive leptonic and semileptonic $B$ decays $B \to ℓ^{-} ν ˉ$ and $B \to D^{(*)} ℓ^{-} ν ˉ$ in the framework of the covariant quark model with built-in infr…

Lepton-mass effects in the decays $H \to Z Z^{} \to ℓ^{+} ℓ^{-} τ^{+} τ^{-}$ and $H \to W W^{} \to ℓ ν τ ν_{τ}$

Stefan Berge, Stefan Groote, Jürgen G. Körner +1

We consider lepton-mass effects in the cascade decays $H \to Z (\to ℓ^{+} ℓ^{-}) + Z^{*} (\to τ^{+} τ^{-})$ and $H \to W^{-} (\to ℓ^{-} ν ˉ_{ℓ}) + W^{+*} (\to τ^{+} ν_{τ})$ .…
