论文摘要
基于杜尔古特（Durgut）在美国物理社会网站的报告的最新初步调查显示，在$ 7 $ $ 7 $和$ 8〜 {\ rm rm rm rm rm rm $ 8〜 {\ rm rm rm $ 8〜 {\ rm rm rm $ 8〜的质量分布中，存在于不变的质量分配中，$ 18.4〜 {\ rm gev} $。它的外观引起了高能物理学的理论家和实验家的注意，因为它可能是$ 18.4〜 {\ rm Gev} $的类似Higgs的玻色子，这将作为标准模型以外的新物理学的信号。我们根据量子场理论对相应数量（生产和衰减速率）进行了计算，并将结果与实验数据进行了比较。我们的数值结果不支持$ 18.4〜 {\ rm gev} $ peacs的断言，对应于中性$ 0^{++} $ boson，该$ boson衰减成$υl^+l^ - $。急需进一步的工作（实验和理论）。
A recent preliminary investigation based on Durgut's report at the American Physical Society site shows a structure at $18.4~ {\rm GeV}$ exists in the invariant mass distribution of $Υl^+l^- ~ (l = e,\, μ)$ at the LHC center-of-mass energy of $7$ and $8~ {\rm TeV}$. Its appearance attracts attention of theorists and experimentalists of high energy physics, because it might be a Higgs-like boson of $18.4~ {\rm GeV}$ which would serve as a signal of the new physics beyond the Standard Model. We have carried out computations on the corresponding quantities (production and decay rates) based on quantum field theory and compared the results with experimental data. Our numerical results do not support the assertion that the $18.4~ {\rm GeV}$ peak corresponds to a neutral $0^{++}$ boson which decays into $Υl^+l^-$. Much further works (both experimental and theoretical) are badly needed.
