论文摘要
与Randall-Sundrum（RS）模型相比，Little Randall-Sundrum（Little RS）模型从风味可观察物中获得了更强的约束。在本文中，我们分析了Little RS中电动领域的影响，对带电瘦素的风味变化。我们将模型的预测与当前限制了违反风味的分支比率为$ \ rightarrow e e $，$τ\ rightarrow e e $ $，$τ\rightarrowμμμ$，$τ\ rightArrow -rightarrowμEE$，$ thouse e $，$ firsarrow e $ thourrow firsarroweμμ$ ti $。我们表明，主要的约束来自$μti\ rightarrow e ti $过程，该过程强烈限制了kk-1量规玻色子质量（$ m_ {kk} $）为$ \ gtrsim 30.7 tev $。然后，我们得出并表明将电脉冲轨迹扇形推广到包括brane局部动力学术语（BLKT）放宽了这一约束至$ \ gtrsim 12 tev $。为了结论，我们评论了可能通过放松对紫外线的不自然薄薄性和刚性的假设来减轻违反大型风味的电流的可能性，并讨论在存在脂肪波动的麸皮下抑制这些电流的可能性。
The Little Randall-Sundrum (Little RS) model receives significantly stronger constraints from the flavour observables in comparison to Randall-Sundrum (RS) model. In this paper, we analyse the effect of the electro-weak sector in Little RS on flavour changing decays of charged leptons. We compare the predictions of the model with the current limits on the flavour violating Branching Ratios of $μ\rightarrow e e e $, $τ\rightarrow e e e $, $τ\rightarrow μμμ$, $τ\rightarrow μe e $, $τ\rightarrow e μμ$ , $μ\rightarrow e γ$, and $μTi \rightarrow e Ti $. And we show that the dominant constraint arises from the $μTi \rightarrow e Ti$ process which strongly limits the KK-1 gauge boson mass ($M_{KK}$) to be $\gtrsim 30.7 TeV $. We then derive and show that generalising the electro-weak gauge sector to include the Brane Localised Kinetic Term (BLKT) relaxes this constraint to $\gtrsim 12 TeV$. Towards the conclusion, we comment on the possibility that the large flavour violating currents can be mitigated by relaxing the assumption regarding the unnatural thinness and rigidity of the UV-brane and discuss the possibility of suppression of these currents in presence of fat fluctuating branes.
