论文摘要
高能偶极蛋白散射的非前瞻性艾科纳尔散射矩阵由于$ c $ -odd三个gluon交换而获得了一个假想的零件。我们介绍了扰动ODDERON振幅的数值估计值，该振幅是偶极子大小，冲击参数，其相对方位角角度和轻度动量$ x $的函数。 The proton is approximated as $ψ_\mathrm{qqq}|qqq\rangle + ψ_\mathrm{qqqg}|qqqg\rangle$, where $ψ_\mathrm{qqq}$ is a non-perturbative three quark model wave function while the gluon emission is computed in light-cone perturbation theory.我们发现，随着$ x $从0.1降低到0.01，Odderon振幅增加。在较低的$ x $时，这种能量依赖的逆转将反映通用小$ x $重新归一化组进化的开始。
The non-forward eikonal scattering matrix for dipole-proton scattering at high energy obtains an imaginary part due to a $C$-odd three gluon exchange. We present numerical estimates for the perturbative Odderon amplitude as a function of dipole size, impact parameter, their relative azimuthal angle, and light-cone momentum cutoff $x$. The proton is approximated as $ψ_\mathrm{qqq}|qqq\rangle + ψ_\mathrm{qqqg}|qqqg\rangle$, where $ψ_\mathrm{qqq}$ is a non-perturbative three quark model wave function while the gluon emission is computed in light-cone perturbation theory. We find that the Odderon amplitude increases as $x$ decreases from 0.1 to 0.01. At yet lower $x$, the reversal of this energy dependence would reflect the onset of universal small-$x$ renormalization group evolution.
