Query: Charged Higgs Production at Linear Colliders in Large Extra Dimensions   In the Two-Higgs-Doublet Model(2HDM) with large extra dimensions(LED), we
study the contributions of virtual Kaluza-Klein(KK) gravitons to 2HDM charged
Higgs production, especially in the two important production processes
$e^+e^-\to H^+H^-$ and $e^+e^-\to H^-t\bar{b}$, at future linear colliders
(LC). We find that KK graviton effects can significantly modify these total
cross sections and also their differential cross sections compared to their
respective 2HDM values and, therefore, can be used to probe the effective scale
$\Lambda_T$ up to several TeV. For example, at $\sqrt{s}=2$ TeV, the cross
sections for $e^+e^-\to H^+H^-$ and $e^+e^-\to H^-t\bar{b}$ in the 2HDM are
7.4fb for $m_{H^-}=150$ GeV and 0.003fb for $m_{H^-}=1.1$ TeV and
$\tan\beta=40$, while in LED they are 12.1fb and 0.01fb, respectively, for
$\Lambda_T=4$ Tev.
