Figure 2.

Comparison between the data and the ZEUSVM MC distributions for the transverse momentum, p_T, of π⁺ and π^- particles, for different ranges of Q², as indicated in the figure. The events are selected to be within 0.65 <M_ππ < 1.1 GeV and |t| < 1.0 GeV². The MC distributions are normalised to the data.
