LHC的反射弹性散射

Reflective Elastic Scattering at LHC

Sergey Troshin, Nikolay Tyurin

摘要:

本文讨论了在LHC和渐近能量下强子与重核碰撞的反射散射效应。结果表明,反射散射可能导致物质密度随能量的增加而降低。得到了强子密度与能量关系的极限形式。碰撞参量表示中弹性散射振幅和两粒子非弹性二元反应幅实部绝对值的么正性上界比弹性散射振幅虚部绝对值的么正性上界小两倍。前一个限制限制了可能的odderon贡献。

英文摘要:

We discuss effects of reflective scattering for hadron and heavy nuclei collisions at the LHC and asymptotical energies. It is shown that the reflective scattering might lead to decreasing matter density with energy beyond the LHC energies. Limiting form of energy dependence of hadron density is obtained. Unitarity upper bound for the absolute value of the real part of elastic scattering amplitude and two-particle inelastic binary reactions amplitudes in impact parameter representation is two times less than the corresponding bound for the imaginary part of the elastic scattering amplitude. The former limit restricts a possible odderon contribution.
