  The upcoming Cherenkov Telescope Array (CTA) project is expected to provide
unprecedented sensitivity in the low-energy ( <~100 GeV) range for Cherenkov
telescopes. In order to exploit fully the potential of the telescopes the
standard analysis methods for gamma/hadron separation might need to be revised.
We study the composition of the background by identifying events composed
mostly of a single electromagnetic subcascade or double subcascade from a
{\pi}0 (or another neutral meson) decay. We apply the standard simulation and
analysis chain of CTA to evaluate the potential of the standard analysis to
reject such events.
