论文摘要
我们描述了LHC的图腾协作的最新结果，即在2.76、7、8和13 TEV的质量中心的弹性横截面测量值。在高质量中心能量的高$ t $时，没有观察到任何结构或共振。 $dσ/dt $的纯指数形式在8和13 TEV处被排除在外。访问非常低的$ t $区域允许在13 TEV处测量$ρ$参数。
We describe the most recent results from the TOTEM collaboration at the LHC, namely the elastic cross section measurements at a center-of-mass on 2.76, 7, 8 and 13 TeV. No structure or resonance is observed at high $t$ at high center-of-mass energies. A pure exponential form of $d σ/dt$ is excluded both at 8 and 13 TeV. Accessing the very low $t$ region allows measuring the $ρ$ parameter at 13 TeV.
