    1  Dear experts,
    2 
    3 I use MadGraph5 interfaced with PY8 and Delphes 3.4.2 to generate events. The delphes card I use is the card for Muon collider ​https://github.com/delphes/delphes/blob/master/cards/delphes_card_MuonColliderDet.tcl. The model I use is sm_full with TauDecay_UFO added. The process I am studying is mu- mu+ > tau+ tau-. My delphes card uses the inclusive Valencia algorithm to reconstruct jets. Obtained jets are then tau-tagged. One of the important variables in my study is the jet mass. My problem is that jet masses obtained using this delphes card are wrong. Half of the masses are positive and half of them are negative in a symmetric discrete pattern. To make sure that the problem relates to the delphes card, I generated a new sample for the same process this time with the ILD delphes card. Jet masses are now correct!

    5 It would be highly appreciated if you let me know how I can get correct jet masses using the delphes card for muon collider.
