In the process of vvH, H->WW, WW->lvqq, the invariant mass of di-jet () is just the module of 4-momentum of . One of di-W boson is real, and the orther is virtual, as shown in the figures below respectively.
It is expected there are one sharp peak at mass and a bump at lower energy than the W mass in the invariant mass spectrum of di-jet.
- The input sample is the vvH, H->WW, WW inclusively decay. We firstly select the final state out using the Monte Carlo truth information.
- Then we need to find out the muon which comes from . This muon is just identified as the or with maximum energy.
- Finally, the invariant mass of is calculated by Jet clustering is not needed.
