$τ$ decay into a pseudoscalar and an axial-vector meson

L. R. Dai, L. Roca, E. Oset

We study theoretically the decay $τ^{-} \to ν_{τ} P^{-} A$ , with $P^{-}$ a $π^{-}$ or $K^{-}$ and $A$ an axial-vector resonance $b_{1} (1235)$ , $h_{1} (1170)$ , $h_{1} (1380)$ , $a_{1} (1260)$ , $f_{1} (1285)$ o…

Triangle singularity in $τ^{-} \to ν_{τ} π^{-} f_{0} (980)$ ( $a_{0} (980)$ ) decays

L. R. Dai, Q. X. Yu, E. Oset

We study the triangle mechanism for the decay $τ^{-} \to ν_{τ} π^{-} f_{0} (980)$ , with the $f_{0} (980)$ decaying into $π^{+} π^{-}$ . This process is initiated by $τ^{-} \to ν_{τ} K^{* 0} K^{-}$ followed…

The $B^{+} \to J / ψ ω K^{+}$ reaction and $D^{} D ˉ^{}$ molecular states

L. R. Dai, G. Y. Wang, X. Chen +3

We study the $B^{+} \to J / ψ ω K^{+}$ reaction, measured by the LHCb collaboration, and show that it is driven by the presence of two resonances, the $X (3940)$ and $X (3930)$ , that are of…

Polarization amplitudes in $τ^{-} \to ν_{τ} V P$ decay beyond the standard model

L. R. Dai, E. Oset

We use a recent formalism of the weak hadronic reactions $τ^{-} \to ν_{τ} M_{1} M_{2}$ to study the helicity amplitudes in $τ^{-} \to ν_{τ} V P$ decay. This recent formalism maps the transitio…

Sterile neutrino and leptonic decays of the pseudoscalar mesons

Chong-Xing Yue, Ji-Ping Chu

We consider a scenario with only one sterile neutrino $N$ , negligible mixing with the active neutrinos $ν_{L}$ , where its interactions with ordinary particles could be describe…

Further study on the textures of neutrino mass matrix for maximal atmospherical mixing angle and Dirac CP phase

Zhi-Cheng Liu, Chong-Xing Yue, Zhen-hua Zhao

In this paper, we derive in a novel approach the possible textures of neutrino mass matrix that can lead to maximal atmospherical mixing angle ( $θ_{23} = π /4$ ) and Dirac CP phas…
