Tevatron中的新双喷粒子IS--Higgs

The New Dijet Particle in the Tevatron IS the Higgs

H. B. Nielsen

摘要:

新发现的\cite{CDFnew} dijet峰在120 GeV到160 GeV的质量区域中与W共同产生,实际上是希格斯玻色子,尽管大多数希格斯玻色子的衰变模式不同。然而,我们的观点是,6 t + 6 $\bar{t}$的束缚态,我们已经在几篇文章\cite{boundfirst} \cite{bound} \cite{dark} \cite{hierarchybound}中提出,很容易轻--可能轻得多--比希格斯粒子质量的一半还轻。在这种情况下,希格斯粒子将主要衰变为两个束缚态。如果这些束缚态确实很轻(比如大约10 GeV),它们衰变为强子的产物就像两个喷流,每个喷流对应一个束缚态。即使我们的束缚态的质量非常小,也不是意外的等压线,因为它是我们模型的一部分,特别是顶夸克-汤川耦合正在被调整,以便精确地使$6t + 6\bar{t}$的这个束缚态变得(大约)无质量。这种调谐是我们的多点原理\cite{old} \cite{SIMPP}的结果,该原理指出,实现的参数/耦合值对应于具有最大的一组退化真空。甚至最近的LHC光子峰值也可能适合我们的模型。

英文摘要:

The newly found \cite{CDFnew} dijet peak in the 120 GeV to 160 GeV mass region produced in co-production with W IS actually a Higgs Boson in spite of the expectation of a different decay pattern for most Higgses. Our point, however, is that the bound state of 6t + 6$\bar{t}$, which we have put forward already in several articles \cite{boundfirst}\cite{bound} \cite{dark}\cite{hierarchybound}, easily could be lighter - possibly much lighter - than half the Higgs mass. Higgs would in this case decay dominantly to two of our bound states. If these bound states were indeed very light (say around 10 GeV) their decay products into hadrons would like two jets, one for each bound state. Even a very small mass for our bound state is not unexpected isofar as it is part of our model that especially the top-quark-Yukawa coupling is being tuned so as to make precisely this bound state of $6t + 6\bar{t}$ become (approximately) massless. This tuning is a consequence of our Multiple Point Principle \cite{old} \cite{SIMPP} which states that the realized parameter/coupling values correspond to having a maximal set of degenerate vacua. Even the very recent LHC-peak in photon photon might be fitted to our model.
