参考国内外现有的τ-c工厂及其探测器的设计结果,给出了BTCF探测器的总体指标. 根据这些指标设计并开发了用于BTCF物理研究的快速蒙特卡罗模拟方法,并用此方法对一系列重要的物理课题进行了蒙特卡罗模拟. 文中描述了该模拟方法的设计思想、程序流程以及这种方法在BTCF可行性研究乃至预制研究阶段的优越性,同时也给出了对若干重要物理问题的模拟结果. 从而论证了建造BTCF的必要性和不可替代性. 相似文献

The doubly weak transition b-dd■ is highly suppressed in the Standard Model,which makes it a potential channel for exploring new physics signals.We present a study of the exclusive two-body wrong sign weak decay ■→K+π-,which belongs to this class,in the perturbative QCD framework.We perform a model independent analysis for various effective dimension-6 operators for which large effects are possible.We further analyze the considered process in the Randall-Sundrum model,including the custodially protected and the bulk-Higgs Randall-Sundrum models.Exploring the experimentally favored parameter space of these models leads to a large and significant enhancement of the decay rate compared to the Standard Model,which might be accessible in future experiments.We propose to search for the wrong sign decay ■→K+π-via flavor-tagged time-dependent analyses,which can be performed at LHCb and Belle-Ⅱ. 相似文献
