Description

We study double Higgs production at the future linear collider in the framework of the two Higgs doublet models through the following channels: e+e-→ΦiΦjZ, Φi=h0, H0, A0, H±. All these processes are sensitive to triple Higgs couplings. Hence observations of them provide information on the triple Higgs couplings that help reconstructing the scalar potential. We also discuss the double Higgs-Strahlung e+e-→h0h0Z in the decoupling limit where h0 mimics the standard model Higgs boson. The processes e+e-→h0h0Z and e+e-→h0H0Z are also discussed in the fermiophobic limit where distinctive signatures such as 4γ+X, 2γ+X, and 6γ+X are expected in the Type-I two Higgs doublet model
