仅对高能数据的拟合不能清楚地区分总强子截面的渐近$\ln s$和$\ln^2s$行为。我们证明,当我们要求这些振幅也平均描述由共振主导的低能量数据时,这不再是正确的。
Fits to high energy data alone cannot cleanly discriminate between asymptotic $\ln s$ and $\ln^2s$ behavior of total hadronic cross sections. We demonstrate that this is no longer true when we require that these amplitudes also describe, on average, low energy data dominated by resonances.
