N(e-) or N(e+) distribution is not coming
Hi Benjamin,
While plotting N(e-) or N(e-), all the events are distributed at N(e-)=0 or N(e+)= 0. Please suggest where could be the mistake.

Shiba

Hi Shiba,
There may be a problem with your delphes card in the electron reconstruction efficiency module. What this means is that there is zero electron/positron recontructed by delphes.
Cheers,
Benjamin

Hi Benjamin,
Another thing, for 100 TeV collider, which card one should use for final states involving 4leptons and 2b-quarks ?

Hi Shiba,
> Thanks. I was using the inbuilt CMS Delphes card. I think earlier you have said that this card is properly validated. Then which card should I use for final states involving 4leptons and 2b-quarks ?
Try cms-ma5tune instead of just cms. This should fix your problem.

We have no special card for the FCC. The best would be to start from the card shipped with delphes.

Hi Benjamin,

Are you saying the following line in my script file while obtaining the .root files
set main.fastsim.
set main.fastsim.
>>We have no special card for the FCC. The best would be to start from the card shipped with delphes.
There is one card in the folder tools/delphes/cards i.e. delphes_

For instance.

Hi Shiba,
You should use delphes and not delphesMA5tune. Once the delphes fastsim is selected, you can load a delphes card that is called cms-MA5tune.

Benj

Hi Benjamin,

it is asking to edit the delphes card. I am not editing anything. I am using the inbuilt one. Hope, it is ok.(Would you like to edit the Delphes Card ? (Y/N)
Answer: N)

Hi Shiba,
But you need to use delphes and not delphes-MA5tune.
Cheers.

Hi Benjamin,
1. Now, I have obtained the distributions by using the .root files obtained from inbuilt Delphes Card and MA5 tuned Delphes card.
In the latter case, N(e-) , N(e+) distribution is coming. But the distributions related to leptons are coming entirely different. Which one is correct ? If you want, I can send the plots. Please suggest some help.
2. What are these Ma5 tuned cards ? what is the difference between the inbuilt Delphes Card and MA5 tuned Delphes card ?

Shiba

I do not know. It depends what is studied. Both may be correct.

We modified a few efficiencies and changed a couple of modules.

Hi Benjamin,
As I have mentioned, in the inbuilt delphes card case N(e-),N(e+) distribution is not coming.
is it OK ? or if possible, what could be the reason for absence of the distribution for N(e-),N(e+).
>>Both may be correct.
would you like to see the distributions in both the cases ? I am bit worried for the lepton distributions in both the cases.

Shiba

Hi Shiba,
I am confused. Could you please confirm that you use delphes with the cms-ma5tune card and that you get empty distributions for both the number of electrons and positrons? If yes, could you please share an hepmc/stdhep file with O(50) events so that I could check myself?
Cheers,
Benjamin

no, when I have used delphes with the cms-ma5tune card, I am getting a non-empty distributions for both the number of electrons and positrons.
My worry is with 1. lepton distributions obtained using CMS delphes card and cms-ma5tune card are coming different.

The lepton efficiencies need to be changed in the card. Otherwise zero are produced, as you have noticed. We tuned the ma5tune cards and we are sure that those ones give meaningful results. In the othercase, it is up to the user to tune his/her own card.

Hi Benjamin,
1. lepton distributions obtained using CMS delphes card and cms-ma5tune card are coming different. which one to trust ?
Additional Info : tail of pT distribution of lepton is entirely different although I have plotted the pT distribution of lepton with same range with same no. of bins. (From this observation, both can not be true. What to you think ?)

None. It depends what you want to do. Please check (both) detector card and verify that the lepton efficiencies in there satisfy your needs.

They can both be correct. The two cards have different lepton reconstruction efficiencies. Therefore, the properties of the reconstructed leptons may be different.

Benjamin
Can you help with this problem?
Provide an answer of your own, or ask shibasipu for more information if necessary.
