在CDF中,我们观察到了几个独占过程:γγ→e+e−和μ+μ−,γ+IP→J/ψ,ψ(2S)和IP+IP→χc。这些截面与QED、HERA光生数据以及gg→χc与另一个胶子交换以屏蔽颜色的理论估计相一致。排他性χc的这种观测,再加上之前对排他性双喷流和排他性γγ候选者的观测,支持了在大型强子对撞机上p+p→p+smh+p的一些理论预测。独有的双轻子提供了精确校准正向质子光谱仪的最佳手段。
In CDF we have observed several exclusive processes: γγ→e+e− and μ+μ−, γ+IP→J/ψ, ψ(2S) and IP+IP→χc. The cross sections agree with QED, HERA photoproduction data, and theoretical estimates of gg→χc with another gluon exchanged to screen the color. This observation of exclusive χc, together with earlier observations of exclusive dijets and exclusive γγ candidates, support some theoretical predictions for p+p→p+SMH+p at the LHC. Exclusive dileptons offer the best means of precisely calibrating forward proton spectrometers.
