1) heany flavor mcson
重味介子
2) charmed baryon
粲味重子
1.
Recently, many new excited charmed baryon states have been discovered, such asΛc(2880)、Λc(2940)、Ξc(2980)和Ξc(3077).
由于这些丰富的质量光谱和相对狭窄的激发态,开启了粲味重子光谱学的新时代。
3) heavy meson
重介子
1.
B, Bs, D and Ds transitions except those inio final stare light pseudoscalar mesons are systematically studied in a relativistic constituent quark model based on the BS formalism and the exclusive semileptonic and two-body nonleptonic weak decay widths of these heavy mesons are calculated.
基于 BS理论框架,利用相对论性的组分夸克势模型,系统地研究B、Bs D和Ds 介子的跃迁(但不包含末态是轻赝标介子的情况),并计算了这些重介子的单举半轻子及2体 末态非轻子弱衰变过程的分支比。
2.
Starting from the QCD potential which emerges from the effective dilaton gluon coupling,the energy levels and the widths of the leptonic decay and radiative transition are calculated for heavy mesons(c and b)and compared with that of the Cornell potenial.
从伸缩子 -胶子有效耦合理论得到的重夸克 -反夸克势模型出发 ,计算了重介子的自旋平均能谱及轻子衰变和辐射跃迁宽度 ,并与Cornell势模型所得到的相应结果作了比较 。

5) ratio of baryon to meson
重子介子比
1.
Using the statistical quark model and the experimental data of hadron yields,we investigate the production rate of quark pairs, the strangeness suppression factor and the ratio of baryon to meson in pp collisions.
利用夸克统计模型和强子产额的实验数据,研究了 反应中的夸克对产生率、奇异抑制因子和重子介子比,得到了这些量随能量的变化规律。
