Decay rates of $Λ_{b}^{0} \to Λ_{c}^{+} ℓ^{-} ν ˉ_{ℓ}$ using helicity analysis and phase-moment parametrization

Sara Rahmani

Based on the helicity method, formulae for the semileptonic transition of $Λ_{b}^{0} \to Λ_{c}^{+} ℓ^{-} ν ˉ_{ℓ}$ including lepton mass effects are derived. In order to calculate the…

Role of $a_{0} (980)$ in the decays $D^{0} \to K^{+} K^{-} η$ and $π^{+} π^{-} η$

Sara Rahmani, Wei Liang, Yu-Wen Peng +3

In present work, we study the reactions $D^{0} \to K^{+} K^{-} η$ and $D^{0} \to π^{+} π^{-} η$ , and find that the $a_{0} (980)$ state plays a dominant role. At the quar…
