论文摘要
我们在五维通用额外的维情况下衡量了非趋势边界本地化项对$ΔB= 2 $转换的影响，在五维通用额外方案中，质量和kaluza-klein模式的几种相互作用的群体和耦合强度相对于最小对应物进行了显着修改。在这种情况下，我们通过评估负责$ΔB= 2 $转换的一环框图来估计夸克，仪表玻色子和充电希格斯的Kaluza-Klein贡献。使用循环函数（从一环框图获得），我们确定了沃尔芬斯坦参数构度中涉及的几个重要元素。此外，通过这些元素，我们还研究了单位三角形的几何形状。此外，我们计算按相应标准模型值缩放的数量$Δm_s$。我们的理论预测结果已与同时可观察到的允许的范围进行了比较。我们当前的分析表明，根据这种情况下的参数，紧凑型半径倒数的下限可以达到可观的较大值（$ \ $ \ of $ \ of 1.48 $ tev甚至更高）。
We measure the impact of nonvanishing boundary localised terms on $ΔB=2$ transitions in five-dimensional Universal Extra Dimensional scenario where masses and coupling strengths of several interactions of Kaluza-Klein modes are significantly modified with respect to the minimal counterpart. In such scenario we estimate the Kaluza-Klein contributions of quarks, gauge bosons and charged Higgs by evaluating the one-loop box diagrams that are responsible for the $ΔB=2$ transitions. Using the loop function (obtained from one-loop box diagrams) we determine several important elements that are involved in Wolfenstein parametrisation. Moreover, with these elements we also study the geometrical shape of unitarity triangle. Besides, we compute the quantity $ΔM_s$ scaled by the corresponding Standard Model value. Outcomes of our theoretical predictions have been compared to the allowed ranges of the corresponding observables simultaneously. Our current analysis shows that, depending on the parameters in this scenario the lower limit on the inverse of the radius of compactification can reach to an appreciable large value ($\approx 1.48$ TeV or even higher).
