-  ​* ​Would an observed excess of j+MET events allow for a distinction of the underlying model? Can the monojet pT distribution differentiate among different SM-DM couplings? An enhancement of the signal for large pT occurs if the coupling is proportional to the exchanged momentum; this happens for a derivative coupling, typically encountered,​ e.g., in compositeness models. ​+Would an observed excess of j+MET events allow for a distinction of the underlying model?

 A preliminary study of the monojet signature in this model was performed in the master thesis by Sylvain Lacroix (2013, in French): see section 3.9 for the case without derivative coupling, and section 4.3 for the addition of the derivative operator. A preliminary study of the monojet signature in this model was performed in the master thesis by Sylvain Lacroix (2013, in French): see section 3.9 for the case without derivative coupling, and section 4.3 for the addition of the derivative operator.
