摘要：
We consider the phenomenology of a fermiophobic Higgs boson (h(f)) at the Large Hadron Collider (LHC) and a e(+)e(-) linear collider (LC). At both machines the standard production mechanisms which rely on the coupling h(f)VV (V=W+/-,Z) can be very suppressed at large tanbeta. In such cases the complementary channels pp-->H(+/-)h(f),A(0)h(f) and e(+)e(-)-->A(0)h(f) offer promising cross sections. Together with the potentially large branching ratios for H+/--->h(f)W(*) and A(0)-->h(f)Z(*), these mechanisms would give rise to double h(f) production, leading to signatures of gammagammagammagamma, gammagammaVV and VVVV.
