$\boldsymbol{N_{\text{f}}=2}$格点量子色动力学中粲夸克偶素的强子参数
Some hadronic parameters of charmonia in $\boldsymbol{N_{\text{f}}=2}$ lattice QCD
摘要:
夸克偶素轻子衰变的现象学有许多有趣的特征:例如,它可以对标准模型之外的场景建立约束,希格斯扇区被轻CP奇态富集。在下面的论文中,我们报道了用双味格点量子色动力学研究$η_c$和$J/ψ$的衰变常数$f_{η_c}$和$f_{Jψ}$。我们还研究了第一径向激发$η_c(2S)$和$ψ(2S)$的一些性质。
英文摘要:
The phenomenology of leptonic decays of quarkonia holds many interesting features: for instance, it can establish constraints on scenarios beyond the Standard Model with the Higgs sector enriched by a light CP-odd state. In the following paper, we report on a two-flavor lattice QCD study of the $η_c$ and $J/ψ$ decay constants, $f_{η_c}$ and $f_{Jψ}$. We also examine some properties of the first radial excitation $η_c(2S)$ and $ψ(2S)$.
