Abstract
The doubly charged Higgs boson H++ may have a second decay channel that decays to two W bosons. Each of these bosons can decay into either lepton-neutrino pairs or quark-antiquark pairs. Using the all-lepton channel gives us a signature of four leptons and missing energy from the neutrinos, a very low-background signature. Doubly charged Higgs bosons’ decay into W bosons is dependent on the vacuum expectation value, or VEV, a physical constant that is unknown. Previous theoretical research has come to varying conclusions on the real value of the VEV. We generate samples of doubly-charged Higgs decay using different potential Higgs masses (300, 800, 1300 GeV) and VEV values (1, 3.5, 5, 9). We find that the cross section of the WW decay channel is not affected by VEV at high Higgs masses.
