非線性交換幾何電弱模型下正負電子對撞
碩士 === 國立清華大學 === 物理學系 === 94 === We study some tree level processes, such as e+e− → e+e−, e−e− → e−e− and e+e− → γγ in the noncommutative electroweak model. We find that the process of e+e− → γγ does not automatically satisfy the Ward identity. To solve this problem, we assume θ0i = ~E 2 NC = 0, θµ...
