Branching ratios and CP asymmetries of the quasi-two-body decays $B_{c} \to K_{0}^{*} (1430, 1950) D_{(s)} \to K π D_{(s)}$ in the PQCD approach

Zhi-Qing Zhang, Zi-Yu Zhang, Ming-Xuan Xie +2

In this paper, we investigate the quasi-two-body decays $B_{c} \to K_{0}^{*} (1430, 1950) D_{(s)} \to K π D_{(s)}$ within the perterbative QCD (PQCD) framework. The S-wave two-meson distr…

Semileptonic $B_{c}$ meson decays to S-wave charmonia and $X (3872)$ within the covariant light-front approach

Zhi-Jie Sun, Si-Yang Wang, Zhi-Qing Zhang +2

In this work, we investigate the semileptonic decays of $B_{c}$ meson to $η_{c} (1 S, 2 S, 3 S)$ , $ψ (1 S, 2 S, 3 S)$ and $X (3872)$ within the framework of covariant light-front quark model (C…

Quasi-two-body decays $B_{c} \to K^{*} h \to K π h$ in the perturbative QCD

Zi-Yu Zhang, Zhi-Qing Zhang, Si-Yang Wang +2

In this work we study the quasi-two-body decays $B_{c} \to K^{*} h \to K π h (h = D, D_{s}, K, π, η, η^{'})$ in the perturbative QCD (PQCD) approach. The two-meson distribution amplitude…

Isospin Equilibration in Neutron Star Mergers

Mark G. Alford, Alexander Haber, Ziyuan Zhang

We analyze the isospin equilibration properties of neutrinoless nuclear ( $n p e$ ) matter in the temperature and density range that is relevant to neutron star mergers. Our analysis i…

Quasi-two-body decays $B_{c} \to D^{*} h \to D π h$ in the perturbative QCD

Yan-Chao Zhao, Zhi-Qing Zhang, Zi-Yu Zhang +2

In this work, we investigate the quasi-two-body decays $B_{c} \to D^{*} h \to D π h$ with $h = (K^{0}, π^{0}, η, η^{'})$ using the perturbative QCD(PQCD) approach. The description of final st…
