The role of triangle singularity in the $B^{0} \to D^{-} π^{+} a_{0} (980) (π^{0} η)$ decay

Wei Wang, Dazhuang He, Xuan Luo

The triangle singularity interpretation of the \replyhe{ $a_{1} (1420)$ } observed by the COMPASS Collaboration has been widely accepted. In this work, we investigate the triangle mecha…

Probing the dark axion portal via $J / ψ$ decays at BESIII and STCF

Zeren Simon Wang, Dazhuang He, Yu Zhang

Large numbers of $J / ψ$ mesons can be resonantly produced at BESIII and STCF at the center-of-mass energy $s = 3.097$ ~GeV. Such $J / ψ$ mesons may undergo rare decays into an axi…

The effects of a scalar singlet Leptoquark at the $Z$ factory

Dazhuang He, Yu Zhang, Hao Sun

We evaluate the observability of the effects of a scalar singlet leptoquark (LQ) in $μ$ and $τ$ -pair productions at the $Z$ factory. In the scenario addressing the charged-current…

Higgs-strahlung at the LHC in the inert doublet model

Dazhuang He, Yu Zhang, Fawzi Boudjema +1

$pp \to W^{\pm} h, Z h$ processes at the LHC are studied in the framework of the inert doublet model (IDM). To quantify the effects of the IDM and their observability in these proce…

The role of triangle singularity in the decay process $D^{0} \to π^{+} π^{-} f_{0} (980), f_{0} \to π^{+} π^{-}$

Dazhuang He, Yiling Xie, Hao Sun

We study the process $D^{0} \to π^{+} π^{-} f_{0} (980), f_{0} \to π^{+} π^{-}$ by introducing the triangle mechanism, in which $f_{0} (980)$ is considered to be dynamically generated from the meso…

Exploring the molecular scenario of X(4160)

Ruitian Li, Dazhuang He, Xuan Luo +1

In this work, we investigate the decays of meson $X (4160)$ in the molecular frame. By using an effective lagrangian approach, we calculate the widths of $X (4160) \to J / ψ ϕ$ , $D^*\bar…

The strong coupling $g_{X J / ψ ϕ}$ of $X (4700) \to J / ψ ϕ$ in the light-cone sum rules

Yiling Xie, Dazhuang He, Xuan Luo +1

We assign the scalar tetraquark and the D-wave tetraquark state for $X (4700)$ and calculate the width of the decay $X (4700)$ $\to J / ψ ϕ$ within the framework of light-cone sum rules…

Triangle mechanism in the decay process $J / ψ \to K^{-} K^{+} a_{1} (1260)$

Xuan Luo, Dazhuang He, Yiling Xie +1

The role of triangle mechanism in the decay process $J / ψ \to K^{-} K^{+} a_{1} (1260)$ is probed. In this mechanism, a close-up resonance with mass $1823$ MeV and width $122$ MeV decays in…

Theoretical study in the $B ˉ^{0} \to J / ψ K ˉ^{* 0} K^{0}$ and $B ˉ^{0} \to J / ψ f_{1} (1285)$ decays

DaZhuang He, Xuan Luo, YiLing Xie +1

We study the decay processes of $B ˉ^{0} \to J / ψ K ˉ^{* 0} K^{0}$ and $B ˉ^{0} \to J / ψ f_{1} (1285)$ to analyse the $f_{1} (1285)$ resonance. By the calculation within chiral unitary…
