Have you tried with higher theta angles, such as 60°?
Maybe the tracking at 20° is a bit problematic... but I am just trying to guess.

Hi Stefano, thank you for reply.
I tried with 60 degree and here is the result:
for antiprotons identification is much better. But protons are still not identified at all.

Here are the pictures.

P.S. In the real simulation I will deal with low polar angles due to conservation laws. As far as I know, 15 degree is already acceptable for the Straw Tracker.
