在LHC上的弹性和衍射散射

Elastic and diffractive scattering at the LHC

V. A. Khoze, A. D. Martin, M. G. Ryskin

摘要:

受13 TeV弹性$pp$散射的新TOTEM数据的启发,我们研究了在双通道程函模型的框架内描述宽能量区间(0.0625至13 TeV)的所有衍射对撞机数据($σ_{\rm tot}, dσ_{\rm el}/dt$,$ρ\equiv$ Re $A$ /Im $A$,\sd)的可能性。我们表明,一个令人满意的描述,可以实现没有奇签名(Odderon)交换的贡献。我们认为QCD Odderon可能的作用,这可能会改善$ρ$的描述,并讨论了奇签名项的重要性,如果振幅超过黑盘限制。

英文摘要:

Inspired by the new TOTEM data on elastic $pp$ scattering at 13 TeV, we study the possibility to describe all the diffractive collider data ($σ_{\rm tot}, dσ_{\rm el}/dt$, $ρ\equiv$Re$A$/Im$A$, \sd) in a wide interval of energy (0.0625 to 13 TeV) in the framework of a two-channel eikonal model. We show that a satisfactory description can be achieved without an odd-signature (Odderon) exchange contribution. We consider the possible role of the QCD Odderon which may improve the description of $ρ$ and discuss the importance of the odd-signature term if the amplitude were to exceed the black disc limit.
