格点Weinberg-Salam模型的数值研究
Numerical investigation of lattice Weinberg - Salam model
摘要：
数值研究了无费米子的格点Weinberg - Salam模型在Weinberg角为$θ_W \sim 30^o$和$α\sim 1/150$附近的裸精细结构常数的情况.我们考虑的标量自耦合对应的裸希格斯质量约150 GeV的值。我们研究了晶格模型的物理希格斯相和非物理对称相之间的相变附近存在的现象。这是相图的区域，在这里我们要研究连续统物理。我们发现的迹象表明，在能量超过1 TeV的非微扰现象成为重要的温伯格-萨拉姆模型。
英文摘要：
Lattice Weinberg - Salam model without fermions for the value of the Weinberg angle $θ_W \sim 30^o$, and bare fine structure constant around $α\sim 1/150$ is investigated numerically. We consider the value of the scalar self coupling corresponding to bare Higgs mass around 150 GeV. We investigate phenomena existing in the vicinity of the phase transition between the physical Higgs phase and the unphysical symmetric phase of the lattice model. This is the region of the phase diagram, where the continuum physics is to be approached. We find the indications that at the energies above 1 TeV nonperturbative phenomena become important in the Weinberg - Salam model.
