一种类似希格斯粒子的赝标量共振

A Pseudoscalar Resonance That Could Resemble the Higgs

Alan R. White

摘要:

如前所述,在具有无质量左手$ {\bf 5 \oplus 15 \oplus 40 \oplus 45^*}$费米子\{QUD\}的SU(5)规范理论中,红外异常动力学产生了一个S矩阵,这可能为标准模型提供了一个非常经济的起源和统一。所有粒子都是束缚态,具有动态产生的质量,并且没有希格斯扇区。本文阐述了顶夸克所起的完全不同的动力学作用。它并没有重现标准模型“$ t\bar{t} $“的事件,而是由$η_6$的多重矢量玻色子衰变--色六重体电弱对称破缺留下的残余赝标量共振--重现了这些事件。$η_6$出现在LHC和Tevatron Z对截面的证据进行了讨论。第二个赝标量共振,$η_3$,包含一个$t\bar{t}$对,并通过坡密子与$η_6$混合。混合后,$η_3$的质量应介于三重态和六重态之间。它也可能有一个衰变模式模式,与LHC和Tevatron的结果比标准模型希格斯玻色子的(质谱确定的)模式更一致,许多人希望已经发现。不幸的是,目前还不可能计算明确的横截面。

英文摘要:

As described previously, in SU(5) gauge theory with massless left-handed $ {\bf 5 \oplus 15 \oplus 40 \oplus 45^*}$ fermions \{QUD\}, an S-Matrix is produced by infra-red anomaly dynamics that might provide an extraordinarily economic origin and unification for the Standard Model. All particles are bound-states, with dynamically generated masses, and there is no Higgs sector. In this paper, the radically different dynamical role played by the top quark is elaborated. It does not reproduce Standard Model "$ t\bar{t} $" events but, instead, these events are reproduced by the multiple vector boson decays of the $η_6$ - the remnant pseudoscalar resonance left by color sextet electroweak symmetry breaking. Evidence that the $η_6$ appears in LHC and Tevatron Z pair cross-sections is discussed. A second pseudoscalar resonance, the $η_3$, contains a $t\bar{t}$ pair and mixes with the $η_6$ via the pomeron. The mixing should give the $η_3$ a mass between the triplet and sextet scales. It could also have a decay mode pattern that is more consistent with LHC and Tevatron results than the (mass spectrum determined) pattern of the Standard Model Higgs boson that many hope has been discovered. Unfortunately, at present, there is no possibility to calculate explicit cross-sections.
