提出了对两个希格斯双峰模型的全面唯象分析，该模型在树级别具有风味变化的标量电流，称为模型 III。系统地纳入了现有实验信息的约束，特别是关于 {Delta}F=2 过程的约束。还检查了罕见 B 衰变、Z {r_arrow} b{anti b} 和 {rho} 参数产生的约束。 e{sup +}e ({mu}{sup +}{mu}) {r_arrow} t{anti c} + {anti t}c、t {r_arrow} c{gamma}(Z,g)、D{sup 0}-{anti D}{sup 0} 和 B{sub s}{sup 0}-{anti B}{sub s}{sup 0} 振荡以及 e{sup +}e 的实验意义(Z) {r_arrow} b{anti s} + {anti b}s 进行了研究，并强调了针对这些的实验努力。他们还强调澄清与 Z {r_arrow} b{anti b} 相关的实验问题的重要性。
A comprehensive phenomenological analysis of a two Higgs doublet model, with flavor changing scalar currents at the tree level, called model III, is presented. Constraints from existing experimental information especially on {Delta}F=2 processes are systematically incorporated. Constraints emerging from rare B-decays, Z {r_arrow} b{anti b}, and the {rho}-parameter are also examined. Experimental implications for e{sup +}e ({mu}{sup +}{mu}) {r_arrow} t{anti c} + {anti t}c, t {r_arrow} c{gamma}(Z,g), D{sup 0}-{anti D}{sup 0}, and B{sub s}{sup 0}-{anti B}{sub s}{sup 0} oscillations, and for e{sup +}e (Z) {r_arrow} b{anti s} + {anti b}s are investigated and experimental effort towards these is stressed. They also emphasize the importance of clarifying the experimental issues pertaining to Z {r_arrow} b{anti b}.
