对撞机上的假暗物质

Fake Dark Matter at Colliders

Spencer Chang, Andre de Gouvea

摘要:

如果暗物质(DM)由弱相互作用大质量粒子(WIMP)组成,它可以在未来的对撞机实验中产生和研究,比如大型强子对撞机。对撞机稳定的WIMP的生产的特点是硬散射事件与大的横向能量丢失。在这里,我们指出,发现这种特征良好的DM信号可能是一个红鲱鱼。我们探索了另一种解释--假暗物质--其中丢失的横向能量的唯一来源是标准模型中微子。我们提出了这样的模型的例子,专注于超对称模型与R-宇称违反。我们还简要讨论了区分假暗物质和新的碰撞稳定粒子的方法。

英文摘要:

If the dark matter (DM) consists of a weakly interacting massive particle (WIMP), it can be produced and studied at future collider experiments like those at the LHC. The production of collider-stable WIMPs is characterized by hard scattering events with large missing transverse energy. Here we point out that the discovery of this well-characterized DM signal may turn out to be a red herring. We explore an alternative explanation -- fake dark matter -- where the only sources of missing transverse energy are standard model neutrinos. We present examples of such models, focusing on supersymmetric models with R-parity violation. We also briefly discuss means of differentiating fake dark matter from the production of new collider-stable particles.
