Dear Pablo,

ps: it is possible to reconstruct both transverse and total momentum. I should put a test macro for displaying such variables.

Yes, you are absolutely right, it is rather simple indeed.
I reconstructed the total momentum for protons and antiprotons with original momentum 1.0 GeV/C and polar angle theta 60°.

For antiprotons I used only those with 50° < theta < 70°, and momentum reconstruction is reliable in this case.
And for protons radius is not reconstructed at all. I hope, this will help.
