p p > t t t~ t~ process gives physics object error

Dear namrata,

The versions 1.5.9 is not the official version since 2013-05-16 (and the release of 1.5.10).
It is very likely that this bug have been fixed in the mean time.
Please try with 2.3.2.

If you still have problem, please provide the MG5_debug file. such that I have all the information that I need to start investigate.

Cheers,

Olivier
