Charged Higgs Production in Association with W Boson at Photon Colliders
Abstract
It is important to explore the Higgs sector in order to identify the model beyond the standard model. We study the charged Higgs production in the
γγ
mode of a linear collider (LC) with 1000 GeV center of mass energy. We show that the cross sections for the
γγ→
H
±
W
∓
processes can be significantly enhanced in the two Higgs doublet model (THDM). The cross section can reach 0.1 - 100 fb which is comparable to other charged Higgs boson production processes at a photon collider. While for other processes the cross sections are too small for
m
±
H
≥500
GeV,
0.1−100
fb can be expected in the
γγ→
H
±
W
∓
processes for
m
±
H
≥570
GeV when

GeV. Therefore, even if the charged Higgs bosons can not be detected at the Large Hadron Collider (LHC), and even if the charged Higgs bosons are too heavy to be detected in other charged Higgs boson production processes at the LC, it may be possible to detect them in this process.
