We study and final sstates at future linear colliders; designing analyses specific to the various final state polarizations allows us to target specific beyond the Standard Model (BSM) effects, parametrized in the form of dimension-6 operators. We find that CLIC can access effects roughly an order of magnitude smaller than HL-LHC or ILC, and two orders of magnitude smaller than LEP. These results are interpreted in the context of well-motivated BSM scenarios-at weak and strong coupling-where we expect correlated effects in Drell-Yann processes. The latter turn out to have better discovery potential, although the diboson processes provide additional discriminating power, potentially furnishing a way to measure the spin and coupling of BSM states.
我们研究未来直线对撞机的末态；针对各种末态极化设计特定的分析方法，使我们能够针对以六维算符形式参数化的特定超出标准模型（BSM）的效应。我们发现，CLIC能够探测到比HL-LHC或ILC小约一个数量级、比LEP小两个数量级的效应。这些结果是在弱耦合和强耦合的动机充分的BSM情景背景下进行解释的，在这些情景中我们预计在Drell-Yann过程中会有相关效应。事实证明，后者具有更好的发现潜力，尽管双玻色子过程提供了额外的区分能力，有可能提供一种测量BSM态的自旋和耦合的方法。
