自然自调谐低质量复合标量

Naturally Self-Tuned Low Mass Composite Scalars

Christopher T. Hill

摘要:

由一对手征费米子组成的标量玻色子在非限制势中与自由外手征费米子有一个有效的汤川耦合$g$。在大距离处,外部费米子的费曼环产生标度不变势$V_{loop}\propto -g^2/{r^{2}}$,其作用于价费米子以分离$ρ=2r$。这通常迫使$s$波基态变形为静态的零质量构型,并且对于缓慢运行的微扰$g$,形成大的外部“护罩”波函数。这与量子力学中Landau和Lifshitz的旧结果有关。无质量的复合标量玻色子基态是一个扩展的对象。红光效应可以为系统产生小质量。这表明了一种由顶夸克和反顶夸克组成的微扰BEH玻色子和一种新的自发电弱对称性破缺的动力学机制。

英文摘要:

Scalar bosons composed of a pair of chiral fermions in a non-confining potential have an effective Yukawa coupling, $g$, to free external chiral fermions. At large distance a Feynman loop of external fermions generates a scale invariant potential, $V_{loop}\propto -g^2/{r^{2}}$, which acts on valence fermions for separation $ρ=2r$. This generally forces the $s$-wave ground state to deform to a static, zero mass, configuration, and for slowly running, perturbative $g$, a large external "shroud" wave-function forms. This is related to old results of Landau and Lifshitz in quantum mechanics. The massless composite scalar boson ground state is then an extended object. Infra-red effects can generate a small mass for the system. This points to a perturbative BEH-boson composed of top and anti-top quarks and a novel dynamical mechanism for spontaneous electroweak symmetry breaking.
