In the framework of the QCD factorization approach, we study the localized CP violations of the B−→K−π+π−, B−→π−π+π−, B−→K−K+K−, B−→π−K+K−, B−→K−π0η and B−→π−π0η decays with and without the a00(9

Abstract We interpret the $$X_1(2900)$$ X 1 ( 2900 ) as an S-wave $${\bar{D}}_1K$$ D ¯ 1 K molecular state in the Bethe–Salpeter equation approach with the ladder and instantaneous approximations for the kernel. By solving the Bethe–Salpeter equ

The hot metal temperature is a key process parameter for blast furnace (BF) ironmaking that reflects the quality of hot metal, the thermal state of BF hearth, the energy utilization efficiency of BF, and many other information. Prediction of the hot

Abstract In this work, we assume that the observed state $$\Xi (1620)$$ Ξ(1620) is a s-wave $$\Lambda {\bar{K}}$$ ΛK¯ or $$\Sigma {\bar{K}}$$ ΣK¯ bound state. Based on this molecule picture, we establish the Bethe–Salpeter equations for $$\Xi

Abstract Within the QCD factorization approach, we study the CP violations in $$B^-\rightarrow K^-\pi ^+\pi ^-$$ B-→K-π+π- and $$B^-\rightarrow K^- f_0(500)$$ B-→K-f0(500) decays. We find the experimental data of the localized CP asymmetry in $

In this work, within the QCD factorization approach, we study the localized integrated CP violation in the B−→π−π+π− decay and the branching fraction of the B−→σπ− decay. Both the resonance and nonresonance contributions are includ

In this work, we study the BK¯ molecule in the Bethe-Salpeter (BS) equation approach. With the kernel containing one-particle-exchange diagrams and introducing two different form factors (monopole form factor and dipole form factor) in the vertex, w

In the framework of the QCD factorization approach, we study the localized violations of the decay with and without the mixing mechanism and observe that the localized violation can be enhanced by this mixing effect when the mass of the pair is in th
