LHC上的矢量暗物质

Vector dark matter at the LHC

Jason Kumar, Danny Marfatia, David Yaylali

摘要:

我们考虑在大型强子对撞机(LHC)上进行单喷流搜索,寻找通过接触算符与夸克相互作用的自旋1的暗物质。如果产生的暗物质粒子具有纵向极化,则产生矩阵元通过能量的因子而增强。我们表明,这种特别有效的搜索策略可以测试模型的能量抑制规模的运营商是大到10^5 TeV。因此,这些搜索可以探测接触算子近似有效的一大类模型。我们发现,接触运营商,允许速度无关的暗物质-核子散射,大型强子对撞机单喷流搜索自旋1暗物质的竞争力或远远超过直接检测搜索取决于散射是自旋无关或自旋相关,分别。

英文摘要:

We consider monojet searches at the Large Hadron Collider (LHC) for spin-1 dark matter that interacts with quarks through a contact operator. If the dark matter particles are produced with longitudinal polarizations, then the production matrix element is enhanced by factors of the energy. We show that this particularly effective search strategy can test models for which the energy suppression scale of the operator is as large as 10^5 TeV. As such, these searches can probe a large class of models for which the contact-operator approximation is valid. We find that for contact operators that permit velocity-independent dark matter-nucleon scattering, LHC monojet searches for spin-1 dark matter are competitive with or far surpass direct-detection searches depending on whether the scattering is spin independent or spin dependent, respectively.
