7 Q H = (H H) 3 at Tree Level, cont. With scalars tree level Q H is possible: Then the question is: (λ ) 2 M 2 µ2 λ M 4 (µ)3 µ M 6 What extended scalar sectors can generate these topologies? Must be an SU(3) c singlet, the Higgs is uncolored. Must be in rep. of SU(2) L w/ λ (H 3 Φ) and/or µ(h 2 Φ) invariant From there hypercharge is a given: H 3 Φ Y φ = {±3Y H, ±Y H } H 2 Φ Y φ = {0, ±2Y H } Tyler Corbett (Melbourne) June 20, / 14

9 Some Group Theory... Clearly a SM singlet and a 2HDM work as we can form H 3 Φ. What other representations work? 2 2 = 3 S + 1 A = 4 S + 2 So triplets will work! R triplet w/ H Hφ must have Y φ = 0 C triplet w/ H 2 Φ must have Y Φ = 2Y H Quadruplets will also work! R quadruplet won t work, because we have either (H H)HΦ or H 3 Φ so Y φ 0 C quadruplet can have H 3 Φ and Y Φ1 = 3Y H C quadruplet can also have (H H)HΦ and Y Φ2 = Y H However, we neglect quadruplet models (haven t completed the analyses yet)...
