强子产生中的异常软光子

Anomalous Soft Photons in Hadron Production

Cheuk-Yin Wong

摘要:

在高能(K+)p、(pi+)p、(pi-)p、pp和(e+)(e-)碰撞中,在强子(主要是介子)的产生过程中,已经观察到超过电磁韧致辐射预期的异常软光子。提出了一个在量子场论中同时产生反常软光子和介子的模型,其中介子的产生是由通量管中底层真空夸克色电荷密度的振荡引起的.由于夸克同时携带色电荷和电荷,色电荷密度的振荡将伴随着电荷密度的振荡,这反过来又会导致在介子产生过程中同时产生软光子。如何生产这些软光子可以解释异常的软光子数据将被讨论。将提出进一步的实验测量来测试模型。

英文摘要:

Anomalous soft photons in excess of what is expected from electromagnetic bremsstrahlung have been observed in association with the production of hadrons, mostly mesons, in high-energy (K+)p, (pi+)p, (pi-)p, pp, and (e+)(e-) collisions. We propose a model for the simultaneous production of anomalous soft photons and mesons in quantum field theory, in which the meson production arises from the oscillation of color charge densities of the quarks of the underlying vacuum in the flux tube. As a quark carries both a color charge and an electric charge, the oscillation of the color charge densities will be accompanied by the oscillation of electric charge densities, which will in turn lead to the simultaneous production of soft photons during the meson production process. How the production of these soft photons may explain the anomalous soft photon data will be discussed. Further experimental measurements to test the model will be proposed.
