MadAnalysis 5

where is a fake electron from

Asked by andy

Hi,

I generate 10k events of p p > z > j j with madgraph, then automatically using pythia and Delphes 3.1.2. After analyzing the LHCO file with the user-friendly fashion of Madananlysis5 (version: Date : 2014/08/01, 1.1.12.1), I obtain a e- (PT 10-20).
The author of Delphes3.1.2 think that Delphes3.1.2 dose not consider the fake lepton. I doubt this is a bug for madanalysis.
Could you help me?

The corresponding lhco and hep files can be downloaded from the following website:

Hi Andy,

I can neither download the file nor understand the exact problem. Could you please share the LHCO file on a non-dropbox website and give more details about the behavior that you observe and that should not be there?

Cheers,

Benjamin

Dear Benjamin,
     Thank you for your reply.

I find a pdg=1 in the LHCO file. The electron should come from the semi-letponic heavy quark decay although delphes does not consider misidentified hadron as lepton. So, Madanalysis should work well.

Many thanks.
