W-Z-Top包包
The W-Z-Top Bags
摘要：
我们讨论了标准模型中一个新的多量子束缚态族，它是由于标准模型中最重的成员，即规范量子$W,Z$和（反）顶夸克$\bar t, t $之间基于Higgs的相互吸引而存在的.我们使用自洽平均场近似，直到一个相当大的粒子数$N$。在本文中，我们不专注于弱束缚，非相对论束缚态，而是“袋”中的希格斯VEV显着修改/耗尽。在最小数$N$以上，这种状态出现强烈依赖于希格斯质量与$W,Z,\bar{t}, t $质量的比值：对于轻希格斯质量的$m_H \sim 50\, GeV$，束缚态从$N\sim O(10)$开始，但对于“现实”希格斯质量的$m_H\sim 100\, GeV$，人们发现亚稳态/束缚$W,Z$袋只适用于$N\sim O(1000)$。我们还发现，在后一种情况下，纯顶袋消失的所有N，虽然顶夸克仍然可以很好地绑定到W袋。预期宇宙学的应用（在配套文件中讨论），这些袋子的“门口状态”的baryosynthesis，我们也认为存在这样的亚稳态袋在有限的温度下，当SM参数，如希格斯玻色子，规范和顶质量显着修改。
英文摘要：
We discuss a new family of multi-quanta bound states in the Standard Model, which exist due to the mutual Higgs-based attraction of the heaviest members of the SM, namely, gauge quanta $W,Z$ and (anti)top quarks, $\bar t, t $. We use a self-consistent mean-field approximation, up to a rather large particle number $N$. In this paper we do not focus on weakly-bound, non-relativistic bound states, but rather on "bags" in which the Higgs VEV is significantly modified/depleted. The minimal number $N$ above which such states appear strongly depends on the ratio of the Higgs mass to the masses of $W,Z,\bar{t}, t $: For a light Higgs mass $m_H \sim 50\, GeV$ bound states start from $N\sim O(10)$, but for a "realistic" Higgs mass, $m_H\sim 100\, GeV$, one finds metastable/bound $W,Z$ bags only for $N\sim O(1000)$. We also found that in the latter case pure top bags disappear for all N, although top quarks can still be well bound to the W-bags. Anticipating cosmological applications (discussed in a companion paper) of these bags as "doorway states" for baryosynthesis, we also consider the existence of such metastable bags at finite temperatures, when SM parameters such as Higgs, gauge and top masses are significantly modified.
