强子对撞机上的四夸克有效算符

Four-Quark Effective Operators at Hadron Colliders

Maikel de Vries

摘要:

将有效算子约束转化为BSM理论的鲁棒性关键取决于BSM粒子的质量和耦合。这是特别相关的强子对撞机的部分子中心的质量能量是周围的自然BSM理论的典型能量尺度。使用Z'和G'模型讨论了应用限制的注意事项,说明了一大类模型的效果。分析表明,有效算符的适用性主要取决于事例中传递能的比值和全理论的质量尺度。此外,基于这些结果,发展了一种方法来重铸现有的实验限制四夸克有效运营商的完整的理论参数空间。

英文摘要:

The robustness of translating effective operator constraints to BSM theories crucially depends on the mass and coupling of BSM particles. This is especially relevant for hadron colliders where the partonic centre of mass energy is around the typical energy scales of natural BSM theories. The caveats in applying the limits are discussed using Z' and G' models, illustrating the effects for a large class of models. This analysis shows that the applicability of effective operators mainly depends on the ratio of the transfer energy in the events and the mass scale of the full theory. Moreover, based on these results a method is developed to recast existing experimental limits on four-quark effective operators to the full theory parameter space.
