How to use ptllmin and ptllmax parameters in run_card.dat

Asked by Prachi Arvind Atmasiddha on 2020-05-26

Hello,

I am trying to generate the following process:
define l+ = e+ mu+ ta+
define l- = e- mu- ta-
define vl = ve vm vt
define vl~ = ve~ vm~ vt~
define wpm = w+ w-
generate p p > w+{0} z{0}, w+ > l+ vl, z > l+ l- @0
add process p p > w+{0} z{0} j, w+ > l+ vl, z > l+ l- @1

But with a ptllmin and ptllmax cuts. I am using madgraph version 2.7.2.

One question is what ptllmin and ptllmax exactly mean? I just wanted to make sure my understanding is correct.

Second, when I run the program with ptllmin = 10.0, I get the following error msg. (I have also attached the debug report after this error msg). I wanted to understand how to use this parameter.

Looks like this is not a frequently used cuts.
(I personally never used it)

By looking at the code (see below)
you can see that this cut is applied on any pair of
 - two neutrino
 - one lepton and one neutrino

for the pair of two lepton, this cut is only applied for same flavor lepton with different charge.

The issue is that starting with MG5, the code optimization is not compatible with such type of flavor cut.
You either have to remove MG5 optimization (using set group_subprocesses False before generating the diagram)
or setup a mass for all flavor lepton (which blocks the optimization creating issues).

I'm not sure what to do about this cuts actually.
I guess this was requested (and implemented) by CMS directly.
But the comment in the run_card is everything but clear so I will change the comment for the next version.

I will also consider if I can add ptcut for "onshell" decay. (like in your case pt cut on the "onshell" Z and the "onshell" W)

Cheers,

Olivier

Hi Olivier,

Thank you very much for the reply.

So, according to you this cut is applied only for 2 leptons in the event? In case of the events I am generating with 4 leptons, which leptons will be used for this cut? So, according to my understanding this cut will be applied on all the combinations (containing 2 leptons out of 4) of leptons, am I correct?

Also, I should set group_subprocesses False or setup mass of leptons in the proc card, am I right?

Are there any other consequences of removing MG5 optimization?

Thank you,

Regards
Prachi

Hi,

No if you have e+ e- mu+ vm
then the cut is applied on
e+ e-
e+ vm
e- vm
mu+ vm
but not
e+ mu+
e- mu+
for
 e+[1] e- e+[2] ve
you have it on
e+[1] e-
e+[1] ve
e- e+[2]
e- ve
e+[2] ve
but not
on
e+[1] e+[2]

This is why madgraph complains since he want to handle both process together but the cut does not allow him to do that safely.

yes

> Are there any other consequences of removing MG5 optimization?

Much slower code, and much more disk space used.

Cheers,

Olivier
