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 / I ¨ $ decays at BESIII and STCF

Zeren Simon Wang, Dazhuang He, Yu Zhang

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

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 $I^¼$ and $I ¨ $ -pair productions at the $Z$ factory. In the scenario addressing the charged-curren…

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…
