Abstract The decays B → D ¯ ∗ ωπ $$ B\to {\overline{D}}^{\left(\ast \right)}\omega \pi $$ are very important for the investigation of ρ excitations and the test of factorization hypothesis for B meson decays. The B + → D ¯ ∗ 0 ω π + $$

Herein, a Sc(OTf)3-catalyzed (3+2) annulation of 2-indolylmethanols with propargylic alcohols is reported. The reaction proceeds via a Friedel–Crafts-type allenylation/5-exo-annulation cascade. In the reaction, 2-indolylmethanol is used as a three-

Melatonin (MT) is a hormone with antioxidant activity secreted by the pineal gland in the human brain, which is highly efficient in scavenging free radicals and plays an important role in the neuro-immuno-endocrine system. Emerging evidence showed th

Abstract We study the contributions of the resonant states K 0 ∗ $$ {K}_0^{\ast } $$ (1430) and K 0 ∗ $$ {K}_0^{\ast } $$ (1950) in the three-body decays B → Kπh (with h = π, K) in the perturbative QCD approach. The crucial nonperturbative in

Abstract We study the quasi-two-body decays $$B\rightarrow D K^*(892) \rightarrow D K\pi $$ B→DK∗(892)→DKπ by employing the perturbative QCD approach. The two-meson distribution amplitudes $$\Phi _{K\pi }^{P\text {-wave}}$$ ΦKπP-wave are ado

Abstract We extend our recent works on the P-wave two-pion resonant contributions to the kaon-pion cases in the hadronic charmless B meson decays by employing the perturbative QCD approach. The concerned decay modes are analysed in the quasi-two-body

In this paper, we studied the quasi-two-body Bc→D(s)[ρ(770),ρ(1450),ρ(1700)→]ππ decays by employing the perturbative QCD (PQCD) factorization approach. The two-pion distribution amplitudes Φππ are applied to include the final-state intera
