轻子与中性弱规范玻色子的弹性散射 ELASTIC SCATTERING OF A NEUTRAL WEAK GAUGE BOSON BY A LEPTON 刘觉平 Liu Jueping 1 first-author 卢斌 Lu Bing 1 武汉大学物理学系 武汉大学物理学系 Department of Physics , Wuhan University Department of Physics , Wuhan University 在Ｗｅｉｎｂｅｒｇ－Ｓａｌａｍ弱电统一理论中，计算了在新粒子产生阈能以下的轻子与中性弱规范子即Ｚ玻色子的弹性散射振幅，以及相应的散射截面角分布。 Based on the Weinberg-Salam unified theory of the electroweak interactions , the amplitude of the elastic scattering between a neutral weak gauge boson and a lepton is calculated by using the standard technique of estimating the Feynman diagrams of the lowest order;and then , the corresponding angular distribution is obtained. A brief discussion of the result is given. 弱电统一理论 中性弱规范玻色子 弹性散射 The electroweak unified theory neutral weak gauge boson elastic scattering O413.1 国家自然科学基金(61672102) 1997-03-01 2021-04-01 3
