$D_{(s)} (2 S)$ and $D_{(s)}^{*} (2 S)$ production in nonleptonic $B_{(s)}$ weak decays

Zhi-Jie Sun, Yong-Jin Sun, Zhi-Qing Zhang +2

Recently, many new excited states of heavy mesons have been discovered in recent experiments, including radially excited states. The production processes of these states from the $…

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…

Subset Sampling and Its Extensions

Jinchao Huang, Sibo Wang

This paper studies the \emph{subset sampling} problem. The input is a set $S$ of $n$ records together with a function $p$ that assigns each record $v\in\mathcal{…
