论文摘要
最近，似乎有证据表明$ C = -1 $ ODDERON在高能量处的质子弹性散射中。在这里，我们讨论了三个不同的中央排斥生产过程$ pp \ to pp（ϕ \ to k^{+} k^{ - }）$，$ pp \ to pp（ϕ \ toμ^{+}+}μ^{ - }）$ k^{+} k^{ - } k^{+} k^{ - } $，作为软odderon Exchange的信息来源。理论结果是在软反应的张量 - 波美龙和载体 - 奥德龙模型中计算的。我们包括振幅水平的吸收性校正。为了描述过去通过WA102协作测量的低能数据，我们还考虑使用重新介绍矢量 - 梅森交换和reggeons进行超级倾斜过程。我们讨论了低能能在低能量下交换Odderon交换的可能证据，并尝试在LHC上做出预测。
There seem to be recently an evidence for $C = -1$ odderon exchange in proton-proton elastic scattering at high energies. Here we discuss three different central-exclusive-production processes $pp \to pp (ϕ\to K^{+}K^{-})$, $pp \to pp (ϕ\to μ^{+}μ^{-})$, and $pp \to pp ϕϕ\to pp K^{+}K^{-}K^{+}K^{-}$, as a possible source of information for soft odderon exchange. The theoretical results are calculated within the tensor-pomeron and vector-odderon model for soft reactions. We include absorptive corrections at the amplitude level. To describe the low-energy data measured in the past by the WA102 collaboration we consider also subleading processes with reggeized vector-meson exchanges and reggeons. We discuss possible evidences for odderon exchange at the low energies and try to make predictions at the LHC.
