125.5 GeV和FNAL的LHC态作为一类新粒子-- $W$ -强子存在的证据

The LHC state at 125.5 GeV and FNAL data as an evidence for the existence of the new class of particles -- $W$-hadrons

Boris A. Arbuzov

摘要:

最近发现的$125.5\, GeV$在$γ\, γ$和$l^+\,l^+\,l^-\,l^-$的质量分布不变时的共振可以初步解释为由两个$W$组成的标量束缚态$X$。在本说明中,我们考虑这个选项,并表明,这种解释同意现有的实验数据,包括最后的大型强子对撞机的发现和$b \bar b$凸点CDF和D 0合作在TEVATRON报告。该方案的应用与已有的数据吻合较好,除了结合态质量$125.5\,GeV$外,不需要任何调整参数。在衰变模式$\,X \to γ\, l^+ l^-$和过程$p + p \to γ\, X$的横截面中,$W$ -强子选择与SM希格斯情况有明显的区别。

英文摘要:

The recently discovered resonance at $125.5\, GeV$ in invariant mass distribution of $γ\, γ$ and of $l^+\,l^+\,l^-\,l^-$ may be tentatively interpreted as a scalar bound state $X$ consisting of two $W$. In the present note we consider this option and show that this interpretation agrees existing experimental data including the last LHC discovery and the $b \bar b$ bump reported by CDF and D0 collaborations at TEVATRON. The application of this scheme gives satisfactory agreement with existing data without any adjusting parameter but the bound state mass $125.5\,GeV$. There are pronounced distinctions of the $W$-hadron option from the SM Higgs case in decay mode $\,X \to γ\, l^+ l^-$ and in the cross-section of process $p + p \to γ\, X$.
