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为一对标准模型（SM）希格斯玻色子（称为共振希格斯对产生），其中一个SM希格斯玻色子衰变为一对b夸克，另一个衰变为一对r轻子。该项目还将涉及寻找非共振希格斯对的产生，即产生一对希格斯玻色子，正如SM中预测的那样，具有与上述相同的最终状态。将分析Run-II ATLAS的全部数据。如果反希格斯粒子产生的横截面与标准模型所预测的一致，那么这个过程就不太可能被观测到。然而，如果信号被BSM物理增强，这可能会被观察到。

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.
