A novel observable for $C\!P$ violation in multi-body decays and its application potential to charm and beauty meson decays

no code implementations24 Feb 2021 Zhen-Hua Zhang

A novel observable measuring the $C\! P$ asymmetry in multi-body decays of heavy mesons, which is called the forward-backward asymmetry induced $C\! P$ asymmetry (FBI-$C\! P$A), $A_{CP}^{FB}$, is introduced.

The impact of $a_0^0(980)-f_0(980)$ mixing on the localized $CP$ violations of the $B^-\rightarrow K^- π^+π^-$ decay

no code implementations4 Feb 2021 Jing-Juan Qi, Zhen-Yang Wang, Chao Wang, Zhen-Hua Zhang, Xin-Heng Guo

In the framework of the QCD factorization approach, we study the localized $CP$ violations of the $B^-\rightarrow K^- \pi^+\pi^-$ decay with and without $a_0^0(980)-f_0(980)$ mixing mechanism, respectively, and find that the localized $CP$ violation can be enhanced by this mixing effect when the mass of the $\pi^+\pi^-$ pair is in the vicinity of the $f_0(980)$ resonance.

$D^{\pm}D^{*\mp}$ Hadronic Atom as a Key to Revealing the $X(3872)$ Mystery

no code implementations15 Dec 2020 Zhen-Hua Zhang, Feng-Kun Guo

We propose a new object, the $X$ atom, which is the $D^\pm D^{*\mp}$ composite system with positive charge parity and a mass of $(3879. 89\pm0. 07)$ MeV, formed mainly due to the Coulomb force.
