Abstract
Equation (6) of the published paper should read:
and equation (9) should be
In the appendix, the following two equations should replace factors 
and 
in equations (A.3) and (A.5), respectively.
The other form factors in the appendix remain unchanged. Because of the above changes, figures 2, 3, 4 and 5 of the published article should be replaced by the following ones:

GeV, 
GeV and 
GeV. The full curve is for tan β = 1.5, the dashed curve is for tan β = 30. ( b) Total cross sections of the subprocess gg → H+H- as functions of with GeV, GeV and 
GeV. The full curve is for tan β = 1.5, the dashed curve for tan β = 30.
Figure 3. Total cross sections of the subprocess gg → H+H- as functions of tan β with GeV, GeV and GeV. The full and dashed curves correspond to 
GeV and 
GeV, respectively.
Figure 4. Total cross sections of the subprocess gg → H+H- as functions of 
with GeV, GeV and 
TeV. The full curve is for tan β = 1.5, the dashed curve for tan β = 30.
Figure 5. ( a) Total cross sections of the process PP → gg → H+H- + X as functions of 
with GeV, GeV and GeV. The full curve is for tan β = 1.5, the dashed curve for tan β = 30. ( b) Total cross sections of the process PP → gg → H+H- + X as functions of with GeV, GeV and GeV. The full curve is for tan β = 1.5, the dashed curve for tan β = 30.
