We summarise the phenomenology of the Higgs sector of the minimal BβL
extension of the Standard Model at an e+eβ Linear Collider. Within such a
scenario, we show that (in comparison with the Large Hadron Collider) several
novel production and decay channels involving the two physical Higgs states
could experimentally be accessed at such a machine. In particular, we present
the scope of the Zβ² strahlung process for single and double Higgs production,
the only suitable mechanism for accessing an almost decoupled heavy scalar
state.Comment: This proceeding of the 2011 International Workshop on Future Linear
