我们研究了质量轻标量与质量重味违反矢量玻色子耦合的唯象。对于几个GeV，这种情况触发了稀有介子衰变，，和;最后两个是最重要的。这些信号都没有经过实验研究，因此，我们提出了分析，以测试这些通道在LHCb。我们证明，该设施的范围延伸到分支比小，和上述渠道，分别。对于，我们表明，稍微修改的版本，目前的多轻子和multitau搜索在大型强子对撞机可以探测宽区域的参数空间的这种情况。总而言之，我们提出的搜索的潜力优于其他限制，如介子混合。
We study the phenomenology of light scalars of massesandcoupling to heavy flavor-violating vector bosons of mass. Forfew GeV, this scenario triggers the raremeson decays,,, and; the last two being the most important ones for. None of these signals have been studied experimentally; therefore, we propose analyses to test these channels at the LHCb. We demonstrate that the reach of this facility extends to branching ratios as small as,,, andfor the aforementioned channels, respectively. For, we show that slightly modified versions of current multilepton and multitau searches at the LHC can probe wide regions of the parameter space of this scenario. Altogether, the potential of the searches we propose outperform other constraints such as those from meson mixing.
