论文摘要
辐射的小型KT光子与多 - 高龙的生产一起散发出异常的过量，这在四十年中挑战了物理社区，但到目前为止尚未提出过解决方案。我们认为该问题植根于与不正确模型的比较，通常称为Bremsstrahlung模型。据信它是从2-> 2+γ过程到辐射多粒子生产2-> n+伽马的延伸，其中初始或最终带电的Hadrons参与了辐射。我们证明，这打破了S-矩阵的单位性，因此与光学定理相矛盾。
The anomalous excess of small-kT photons radiated along with multi-hadron production, is challenging the physics community over four decades, but no solution has been proposed so far. We argue that the problem is rooted in the comparison with an incorrect model, usually called bremsstrahlung model. It is believed to be an extension of the Low theorem from the 2 -> 2+gamma process to radiative multi-particle production 2 -> n+gamma, where either initial, or final charged hadrons participate in radiation. We demonstrate that this breaks down unitarity of the S-matrix, so contradicts the optical theorem.
