The near-threshold cross section of $e^{+} e^{-} \to Ω^{-} Ω ˉ^{+}$ : Heavy-flavor rescattering and physics-informed deep learning

Sara Rahmani

Recent precision measurements of the $e^{+} e^{-} \to Ω^{-} Ω ˉ^{+}$ cross section by the BESIII collaboration provide a valuable opportunity to probe complex hadronic rescattering mechani…

Decay rates of $I^_{b}^{0} \to I^_{c}^{+} ℓ^{-} I^ˉ ½_{ℓ}$ using helicity analysis and phase-moment parametrization

Sara Rahmani

Based on the helicity method, formulae for the semileptonic transition of $I^_{b}^{0} \to I^_{c}^{+} ℓ^{-} I^ˉ ½_{ℓ}$ including lepton mass effects are derived. In order to calculate t…

Weak decays of $B_{s}$ to $D_{s}$ based on the helicity analysis

Sara Rahmani

Employing dipole and exponential hadronic transition form factors and helicity analysis combined with the Lattice QCD input, we present a detailed study of the decays $B_s \to D_s^…

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

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

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