高能质子-质子散射中的宇称破缺

Parity violation in high-energy proton-proton scattering

A. I. Milstein, N. N. Nikolaev, S. G. Salnikov

摘要:

提出了一种新的方法来描述极化质子与高能质子散射过程中的宇称破缺。结果表明,在树近似下,质子-质子散射的P-奇振幅比质子-中子散射的P-奇振幅小得多。质子-质子散射中P奇不对称性的主要来源是由于电荷交换强相互作用引起的辐射修正。我们预测非弹性截面的不对称性远小于弹性截面的不对称性。

英文摘要:

A new approach is proposed to describe the parity violation in the process of scattering of a polarized proton by a proton at high energies. It is shown that in the tree approximation the P-odd amplitude of proton-proton scattering is substantially smaller than the P-odd amplitude in proton-neutron scattering. The main source of P-odd asymmetry in proton-proton scattering is radiative corrections due to the charge-exchange strong interaction. We predict that the asymmetry in the inelastic cross section is substantially less than the asymmetry in the elastic cross section.
