Search for di-Higgs production in the hh-bbrr channel using data from the ATLAS experiment at the Large Hadron Collider

该项目是寻找一个超越标准模型(BSM)的希格斯玻色子衰变到一对标准模型(SM)希格斯玻色子(称为共振希格斯对产生)，其中一个标准模型(SM)希格斯衰变到一对b夸克，另一个衰变到一对r轻子。该项目还将包括搜索非共振希格斯对产生，即SM中预测的一对希格斯玻色子的产生，其最终状态与上述相同。将分析完整的RUN-II ATLAS数据。如果双希格斯产生的截面如标准模型所预测的那样，则不太可能观察到这一过程。然而，如果信号被BSM物理增强，这是可以观察到的。

The project is a search for a Beyond-the-Standard-Model (BSM) Higgs boson decaying to a pair of Standard Model (SM) Higgs bosons (known as resonant Higgs pair-production), where one SM Higgs decays to a pair of b-quarks and the other to a pair of r leptons. The project will also involve searching for non-resonant Higgs pair-production, i.e. the production of a pair of Higgs bosons as predicted in the SM, with the same final state as described above.The full Run-II ATLAS data will be analysed. If the cross-section for di-Higgs production is as predicted by the Standard Model, it is unlikely that this process will be observed. However, if the signal is enhanced by BSM physics, this may be observed.
