论文摘要
我们在$ sp（4）$ sp（4）$ sp（4）$ sp（4）$ sp（4）$ sp（4）$ sp（4）$ sp（4）中，在反对称表示中具有三个dirac fermions的质量和衰减常数的数值计算。相应的连续性理论在对复合材料希格斯，部分顶部综合和复合暗物质模型的某些超紫罗兰的完整实现中起着重要作用。此外，我们以旋转$ 0 $和$ 1 $的频道以及矢量介子的第一个激动状态来测量其他调味的介子的质量。使用梯度流来设置量表，我们进行了连续外推，并显示了该理论的介子光谱的初步结果。
We perform numerical calculations of masses and decay constants of the lightest (flavoured) pseudoscalar, vector and axial vector mesons in the $Sp(4)$ lattice gauge theory with three Dirac fermions in the antisymmetric representation. The corresponding continuum theory plays an important role in certain ultra-violet complete realisations of composite Higgs, partial top compositeness, and composite dark matter models. In addition, we measure the masses of other flavoured mesons in spin-$0$ and $1$ channels, as well as the first excited state of the vector mesons. Using the gradient flow to set the scale, we carry out the continuum extrapolation and show preliminary results for the meson spectrum of the theory.
