| 英文摘要 | Measuring the triple Higgs boson coupling is a crucial task in the LHC and future collider experiments. We apply the message passing neural network (MPNN) to the study of nonresonant Higgs pair production process pp -> hh in the final state with 2b + 2l + E-T(miss) at the LHC. Although the MPNN can improve the signal significance, it is still challenging to observe such a process at the LHC. We find that a 2 sigma upper bound (including a 10% systematic uncertainty) on the production cross section of the Higgs pair is 3.7 times the predicted Standard Model cross section at the LHC with the luminosity of 3000 fb(-1), which will limit the triple Higgs boson coupling to the range of [-3, 11.5]. |
