论文摘要
在这项工作中，我们建议Odderon是一个奇怪的glueball张量Spin-3。为了证明我们的建议，我们通过在此过程中包括Spin-3 Odderon和Spin-2 Pomeron Exchange的贡献来研究$ pp $和$ p \ bar p $弹性散射。现象学有效的Lagrangian方法用于计算$ PP $和$ p \ bar p $弹性散射幅度在树一级。此外，这项工作已使用了Odderon和Pomeron繁殖者的Donnachie-Landschoff Ansatz。我们将$ PP $和$ p \ bar p $散射的各种实验数据符合理论结果，以确定当前工作中的模型参数。通过使用模型参数，评估了Tensor Odderon Regge轨迹的咀嚼曲线图。结果，Odderon Spin-3质量预计为3.2 GEV。此外，我们的模型的总横截面与图腾的结果及其外推D0协作的结果兼容。此外，总横截面还满足了在Regge极限处的Friossart。
In this work, we propose that the odderon is a Regge odd-glueball tensor spin-3. To demonstrate our proposal, we study the $pp$ and $p\bar p$ elastic scattering by including contributions of the spin-3 odderon and spin-2 pomeron exchange in the processes. The phenomenological effective Lagrangian approach is used to calculate the $pp$ and $p\bar p$ elastic scattering amplitudes at the tree level. In addition, a Donnachie-Landschoff ansatz of the odderon and pomeron propagators has been used in this work. We fit the theoretical results with the various experimental data of the $pp$ and $p\bar p$ scattering at the TeV scale to determine the model parameters in the present work. By using the model parameters, the Chew-Frautschi plot of the tensor odderon Regge trajectory is evaluated. As a result, the odderon spin-3 mass is predicted to be 3.2 GeV. In addition, the total cross-section of our model is compatible with the results from TOTEM and its extrapolation from D0 collaboration. Moreover, the total cross-section also satisfies the Friossart bound at the Regge limit.
