反常γ-γ相互作用

Anomalous gamma gamma interaction

Philip Yock

摘要:

LEP 2的数据在高pT的γ-γ相互作用中的强子产生超过QCD的预测约一个数量级。这个过程的振幅与夸克电荷的平方和成正比。这些数据暗示了夸克具有单位电荷或更大电荷的模型。可以用ILC或CLIC进行明确的测试,但等离子体尾流场电子对撞机可能是最实惠的选择。

英文摘要:

Data from LEP2 on hadron production in gamma gamma interactions at high pT exceed the predictions of QCD by about an order of magnitude. The amplitude for the process is asymptotically proportional to the sum of the squares of the charges of quarks. The data are suggestive of models where quarks have unit charges, or larger. Unequivocal tests could be made with the ILC or CLIC, but a plasma wakefield e-e- collider might provide the most affordable option.
