Delphes not matching generator

Description

Hi,

I have generated a Dark Matter sample in Powheg with 2 jets and 2 DM particles in the final state. I have then run this through Delphes using the default CMS detector card.

I have compared the distributions from the Powheg generated lhe file with those from the Delphes output. Attached, as an example, I show the leading jet pT and MET distributions. The results are completely different - why could this be?

As a check, running the lhe file through our private detector simulation does match the generator results.

Thanks,
Christian

Hi,

could you please attach a small event sample, and specify which card and Delphes version you are using?

thanks,
Michele
