My model is the following

File gen https://www.dropbox.com/s/z1xw3yy30dwkvw3/test.gen?dl=0
File mod https://www.dropbox.com/s/fk945tq7gmf2s0y/test.mod?dl=0
File pars https://www.dropbox.com/s/0d3i6scls57mwr1/test.pars?dl=0

where there is a real scalar Sk with multiderivative interactions.

When I compute the amplitude for Sk Sk > Sk SK, In the exprssion of the amplitude, I get a strange term which is called “xi” Subscript[S[ SequenceForm[“Gen”, 5]]. What is it?

Thank you very much!
