In this paper, the most general Lagrangian for the interaction of W＇ with top and bottom quarks is considered. This Lagrangian consists of V- A and V ＋ A structure with in general complex couplings. Such interactions produce an Electric Dipole Moment （EDM） for the top quark at one loop level. We predict the allowed ranges for the mass and couplings of W＇ by using the upper limit on the top quark EDM.展开更多

The tone of this series of aggressive actions was set by Toyotomi Hideyoshi, was continued in the Meiji Restoration and magnified in the Showa era, crystallizing into a pervading pattern of thought and action hiding behind the facts. Those post-World War II views that propose to cut the connections among these wars launched by Japan do not conform to the way Japanese said and behaved in the past but merely endorse some contemporary Japanese academic opinions. Therefore, exploring the facts and hidden logic linking these wars and restoring the original attributes of each regional war may be of benefit to fundamental studies and realistic concerns about Eastern Asian issues.展开更多
