每天的QCD Reggeon场论:包括Pomeron环

QCD Reggeon Field Theory for every day: Pomeron loops included

Tolga Altinoluk, Alex Kovner, Michael Lublinsky, Javier Peressutti

摘要:

导出了高能强子散射振幅的演化方程。我们的推导包括了强子波函数中有限部分子密度的非线性效应以及多重散射对稠密强子目标散射的影响。因此,它包括Pomeron环。它是基于\cite{foam}中导出的强子波函数的演化。演化方程的核定义了QCD Reggeon场论的第二量子化哈密顿量,即超出目前所考虑的极限的$H_{RFT}$。两个以前已知的限制的演变:稀释目标(JIMWLK限制)和稀释弹丸(KLWMIJ限制)直接从我们的最终结果恢复。哈密顿量$H_{RFT}$适用于任意密度强子射弹/靶的散射振幅的演化--从“偶极-偶极”到“核-核”散射过程。

英文摘要:

We derive the evolution equation for hadronic scattering amplitude at high energy. Our derivation includes the nonlinear effects of finite partonic density in the hadronic wave function as well as the effect of multiple scatterings for scattering on dense hadronic target. It thus includes Pomeron loops. It is based on the evolution of the hadronic wave function derived in \cite{foam}. The kernel of the evolution equation defines the second quantized Hamiltonian of the QCD Reggeon Field Theory, $H_{RFT}$ beyond the limits considered so far. The two previously known limits of the evolution: dilute target (JIMWLK limit) and dilute projectile (KLWMIJ limit) are recovered directly from our final result. The Hamiltonian $H_{RFT}$ is applicable for the evolution of scattering amplitude for arbitrarily dense hadronic projectiles/targets - from "dipole-dipole" to "nucleus-nucleus" scattering processes.
