unreacted force field for MD simulation of HMX

Hello there,
I am currently studying the properties of HMX (including C H N O) using LAMMPS. I need a unreacted force field to perform MD simulation. Does anybody have any idea that if LAMMPS has such force field? I found a paper on unreacted force field of RDX (title: Nonreactive molecular dynamics force field for crystalline hexahydro-1,3,5-trinitro-1,3,5 triazine). I don 't know if it has been included in LAMMPS. Thanks for your response!

since *you* have the paper, you are yourself in the best position to
answer your question:
study the paper, check out what functional form of a potential is used
to describe the interactions, compare to the list of potentials
implemented in LAMMPS and see if you get matches for all of them. if
you do, then the answer is "Yes". otherwise "no". please note that in
many cases missing functional forms can be implemented in LAMMPS using
"table" styles.
