论文摘要
我们计算出接近复合Higgs模型的两种陈述su（4）晶格量表理论中的低能常数$ l_ {10} $。由此，我们获得了新的强部门对$ s $参数的贡献。这导致了对真空错位参数$ξ$的上限，这与此结合的当前估计值相似。我们的结果在大型系统不确定性中与大$ n_c $缩放期望一致。
We calculate the low-energy constant $L_{10}$ in a two-representation SU(4) lattice gauge theory that is close to a composite-Higgs model. From this we obtain the contribution of the new strong sector to the $S$ parameter. This leads to an upper bound on the vacuum misalignment parameter $ξ$ which is similar to current estimates of this bound. Our result agrees with large-$N_c$ scaling expectations, within large systematic uncertainties.
