我们能理解直到LHC能量的弹性散射吗?

Do we understand elastic scattering up to LHC energies?

Jacques Soffer

摘要:

在ISR、SPS和Tevatron对撞机上对高能\bar p-p和pp弹性的测量,为研究散射振幅的行为提供了有用的信息。随着LHC对撞机的运行,在能量域上迈出了一大步,这为我们提供了一个独特的机会来改进我们对弹性散射振幅的渐近机制的认识,并验证我们的理论方法的有效性,来描述总截面σ_{tot}(s),总弹性截面σ_{el}(s),前向振幅ρ(s)的实部与虚部之比和微分截面dσ(s,t)/dt。

英文摘要:

The measurements of high energy \bar p p and pp elastic at ISR, SPS and Tevatron colliders have provided usefull informations on the behavior of the scattering amplitude. A large step in energy domain is accomplished with the LHC collider presently running, giving a unique opportunity to improve our knowledge on the asymptotic regime of the elastic scattering amplitude and to verify the validity of our theoretical approach, to describe the total cross section σ_{tot}(s), the total elastic cross section σ_{el}(s), the ratio of the real to imaginary parts of the forward amplitude ρ(s) and the differential cross section dσ(s,t)/dt.
