Polarized observables in $τ \to V V ν_{τ}$ decays

Vindhyawasini Prasad, Hiroyuki Umeeda

We study polarization observables in $τ^{-} \to V_{1}^{-} V_{2}^{0} ν_{τ}$ decays for $(V_{1}^{-}, V_{2}^{0}) = (ρ^{-}, ρ^{0}), (ρ^{-}, ω), (K^{*-}, ρ^{0}), (K^{*-}, ω), (ρ^{-}, K ˉ^{* 0})$ using the helicity…

$b \to c u ˉ q$ decay and CP violating observables in the presence of new physics contributions

Xuanning Guo, Albertus Hariwangsa Panuluh, Hiroyuki Umeeda +1

In this work, a comprehensive analysis for processes related to $b \to c u ˉ q (q = d, s)$ transitions are carried out, including new physics contributions. In light of a recent ten…
