Abstract: Inspired by the recent observation of the $\Xi_{cc}^{++}$ by LHCb collaboration, we explore the "decay constants" of doubly heavy baryons in the framework of QCD sum rules. With the $\Xi_{cc}, \Xi_{bc}, \Xi_{bb}$, and $\Omega_{cc}, \Omega_{bc},… read more here.

Abstract: Motivated by the rapid development of heavy flavor physics experiment, we study the tree-dominated nonleptonic $\bar{B}_{u,d,s}^* \to D_{u,d,s}^*V$~($V=D^{*-},D_s^{*-},K^{*-},{\rho}^-$) decays within the factorization approach. The relevant transition form factors are calculated by employing the covariant light-front… read more here.

DOI: 10.1103/physrevc.100.014309
Abstract: Half-lives of ${\ensuremath{\beta}}^{+}$ decay and electron capture are studied in some selected superheavy nuclei produced in hot-fusion reactions, namely, $^{290}\mathrm{Fl}$, $^{293}\mathrm{Mc}$, $^{294}\mathrm{Lv}$, and $^{295}\mathrm{Ts}$. The nuclear structure is described microscopically from deformed self-consistent Skyrme Hartree-Fock… read more here.

DOI: 10.1103/physrevd.104.114035
Abstract: We present analytical results for master integrals emerging in the computation of differential rates for inclusive weak decays of heavy flavors at next-to-leading order (NLO) in QCD. As an immediate physical application, these master integrals… read more here.

DOI: 10.1103/physrevd.98.056002
Abstract: The discovery of doubly heavy baryon provides us with a new platform for precisely testing Standard Model and searching for new physics. As a continuation of our previous works, we investigate the FCNC processes of… read more here.

DOI: 10.1140/epjc/s10052-021-08954-8
Abstract: We perform a SU(3) analysis for both semi-leptonic and non-leptonic heavy meson weak decays into a pseudoscalar meson and a fully-light tetraquark in 10 or 27 representation. A reduction of the SU(3) representation tensor for… read more here.
