摘要:

在文献中,$(-ϕ^{4})$理论的渐近自由性质通常是从实线计算中得出的,而该理论是一个非实线理论。本文用平均场方法检验了$(-ϕ^{4})_{3+1}$理论中渐近自由的存在性。在这种方法中,与原来的哈密顿相反,得到的有效哈密顿是一个真正的线。因此,这项工作类似于在$\mathcal{PT}$ -对称$(-ϕ^{4})$理论的渐近自由属性的存在的第一个合理的分析。在这方面,我们计算了三个不同的振幅的不同的正尺寸(质量单位),并发现它们都去非常小的值在高能量标度(小耦合)与渐近自由性质的理论的精神。为了检验我们的计算的有效性,我们得到的真空凝聚的渐近行为的耦合,解析,并发现,控制因子$Λ$的值$\frac{(4 π)^{2}}{6}= 26. 319$相比,从文献中得到的结果$Λ=26.3209$通过数值预测。我们断言,本文所预言的高能尺度下的大质量不爆破,有力地表明了著名的Higgs机制的等级问题在具有$\mathcal{PT}$对称的Higgs机制的标准模型中得到解决的可能性.

英文摘要:

In the literature, the asymptotic freedom property of the $(-ϕ^{4})$ theory is always concluded from real-line calculations while the theory is known to be a non-real-line one. In this article, we test the existence of the asymptotic freedom in the $(-ϕ^{4})_{3+1}$ theory using mean field approach. In this approach and contrary to the original Hamiltonian, the obtained effective Hamiltonian is rather a real-line one. Accordingly, this work resembles the first reasonable analysis for the existence of the asymptotic freedom property in the $\mathcal{PT}$-symmetric $(-ϕ^{4})$ theory. In this respect, we calculated three different amplitudes of different positive dimensions (in mass units) and find that all of them goes to very small values at high energy scales (small coupling) in agreement with the spirit of the asymptotic freedom property of the theory. To test the validity of our calculations, we obtained the asymptotic behavior of the vacuum condensate in terms of the coupling, analytically, and found that the controlling factor $Λ$ has the value $\frac{(4 π)^{2}}{6}= 26. 319$ compared to the result $Λ=26.3209$ from the literature which was obtained via numerical predictions. We assert that the non-blow up of the massive quantities at high energy scales predicted in this work strongly suggests the possibility of the solution of the famous hierarchy puzzle in a standard model with $\mathcal{PT}$-symmetric Higgs mechanism.
