在已发表的论文中，γγ→γγ的横截面被高估了2倍。事件的数量和统计意义必须得到纠正。该系数是截面的总系数，与能量中心或散射角无关。因此，事件γγ→γγ的数量减少了一半。
In the published paper the cross-section for γγ→ γγ was overestimated by a factor of 2. The number of events and statistical significance must be corrected. The factor is an overall coefficient of the cross section and is independent of center of energy or scattering angle. Therefore, the number of events γγ→ γγ is reduced by half.
