Summary, in English

We present a new method for matching the two twin-processes gb → H±t and gg → H±tb in Monte Carlo event generators. The matching is done by defining a double-counting term, which is used to generate events that are subtracted from the sum of these two twin-processes. In this way we get a smooth transition between the collinear region of phase space, which is best described by gb → H ±t, and the hard region, which requires the use of the gg → H±tb process. The resulting differential distributions show large differences compared to both the gb → H±t and gg → H±tb processes illustrating the necessity to use matching when tagging the accompanying b-jet.
