提出了一种利用粒子对撞机上的测量数据为超越标准模型（BSM）理论提供一般一致性约束的新方法。该方法，“约束新理论使用铆钉”，Contur，利用的事实，粒子水平的差分测量相空间的基准区域具有高度的模型无关性。因此，这些测量可以与蒙特卡罗发生器中以非常通用的方式实现的BSM物理进行比较，允许考虑比通常情况更广泛的最终状态。Contur方法应被视为对直接搜索的发现潜力的补充，旨在消除在许多（但可能不是所有）测量与标准模型一致的情况下不一致的BSM建议。我们证明，使用一个有竞争力的简化暗物质模型，这种方法的力量。Contur方法对于其他模型和未来的测量具有高度可扩展性。
A new method providing general consistency constraints for Beyond-the-Standard-Model (BSM) theories, using measurements at particle colliders, is presented. The method,‘Constraints On New Theories Using Rivet’, Contur, exploits the fact that particle-level differential measurements made in fiducial regions of phase-space have a high degree of model-independence. These measurements can therefore be compared to BSM physics implemented in Monte Carlo generators in a very generic way, allowing a wider array of final states to be considered than is typically the case. The Contur approach should be seen as complementary to the discovery potential of direct searches, being designed to eliminate inconsistent BSM proposals in a context where many (but perhaps not all) measurements are consistent with the Standard Model. We demonstrate, using a competitive simplified dark matter model, the power of this approach. The Contur method is highly scaleable to other models and future measurements.
