摘要:

本文计算和分析了标量色八重态对LHC共振$t\bar{t}$对产生的贡献。结果表明,这种贡献的标量色八重态$F_2$预测的极小模型与四色夸克-轻子对称性是$\sqrt{s}=13$ TeV的约几倍于$750 < m_{F_2} < 1800$ GeV和$400 < m_{F_2} < 750$ GeV可以超过10%。同时指出,由于双喷流质量谱中的单圈有效双胶子相互作用很小,寻找标量八重态$F_2$作为共振态是困难的。

英文摘要:

The scalar color octet contribution to the resonance $t\bar{t}$-pair production at the LHC is calculated and analysed with account of the one loop effective two gluon vertex. It is shown that this contribution from the scalar color octet $F_2$ predicted by the minimal model with the four color quark-lepton symmetry is for $\sqrt{s}=13$ TeV of about a few percents for $750 < m_{F_2} < 1800$ GeV and can exceed 10% for $400 < m_{F_2} < 750$ GeV. It is also pointed out that the search for the scalar octet $F_2$ as the resonance in the dijet mass spectra seems to be difficult because of the smallness of its one loop effective two gluon interaction.
