loop_qcd_qed_sm package related

Asked by SUBHASISH BEHERA

Hi,
    I am using MG 2.3.0.
    Here I import the inbuilt package "loop_qcd_qed_sm" to generate Z > b b~ /g+ g0 [QED] ....For which I have set the param.dat and run.dat (with usual values) and run the process but it is taking more than 24 hours and seems it struck some where and showing no progress in process... I think it is not going to finish and has some serious problem... The speed of the computer is too good to do other processes ....What shall I do ?

   It goes on continuing for days but not finished yet .

To my knowledge this is not a type of generation that we support. I'm actually thinking that this is a bug that the code let you go that far. Marco do you confirm that? Cheers, Olivier

Hi Subhasish,
QED corrections are not enabled yet in the current version of MG5_aMC, as they are still work in progress.
For the moment you can compute and output QED loop matrix element with [virt=QED], but not more than that.
I am actually quite surprised you don't get any error, but for sure the code which is output is going to give wrong numbers.

Cheers,

Marco

Dear Marco,

You are absolutely right here.
During the launch it gives error.

1. Will the new version come with the NLO enabled QED process ?
2. Do we need to write the UFO file which will have special feature enabled for QED loop etc OR the same UFO will work ?

Thanks,
Subhasish

Hi Subhasish,
you can do EW corrections with MG5_aMC v 3.X (arXiv:1804.10017). For the UFO, you need the R2 and UV counterterms for the EW corrections if you want to compute them.
Let us know if you still have issues.
Best,

Marco

Dear Marco,

Many thanks for the info.

I tried with the latest "MG5_aMC_v3_0_1_beta".
The QCD loop gives cross-section directly but not the [virt=QED] processes.
Why is that ?

Can you comment more ?

I got something like the following:

Hi,
If you use [virt=QED] or [virt=QCD], then you are only generating the virtual matrix element as a standalone output. In this case "launch" will evaluate the matrix element in one random PS point.
In order to get the NLO cross section, you must use [QCD] or [QED], without "virt=" in front of it.
Does this answer your question?

Note that lepton-lepton collisions are not yet supported by MG5_aMC at NLO EW.
Best,

Marco

Dear Marco,

Many thanks for your reply.

Can I use "the virtual matrix element as a standalone output for NLO EW" to
use in some other program to get the idea of cross-section in case of
lepton collider ? If so, can you give some idea ?

Thanks in advance.

Thanks,
Subhasish

Dear Subhasish,
If you tell me more about what you need to do, I can better help you. In
this thread you mentioned both

the latter being loop induced.

Loop induced processes should work OK.

Dear Marco,

My apology for making you confuse.
In fact I had posted two questions in the launchpad. Both are related to
NLO EW.

Can you provide some other mail id (other than launchpad), so that I can
describe in more detail ?

Thanks,

Hi Subhasish,
we can continue to use launchpad (this won't bother anyone), so that what I
will answer to you will be of help also for other users.

Dear Marco,

Yes I agree with your suggestion.
The process I was looking was at lepton-lepton interactions, and as you
have mentioned that for lepton collider it has not been implemented.
Is it because you have collinear divergences due to photon loop etc ? Can
you comment more ?

I tried with the model "loop_qcd_qed_sm-full" for the process : e- e+ > h a
[all=QED], which gives me the following :

INFO: P0_emep_ha done.

Dear Subasish,
ok, so, by loading the loop_qcd_qed_sm-full, you include the electron mass
and its yukawa coupling. So e+ e-> h a is tree-level at LO, and with [QED]
you ask MG to compute the full NLO corrections. However, for a fixed-energy
collider (currently no ISR/Beamstrahlung effects are included so the
collision energy is fixed to the nominal collider energy) the phase-space
mapping that we have implemented for the FKS subtraction does not work, so
it is not possible yet to compute NLO EW corrections at lepton colliders.

If instead, you load the model
loop_qcd_qed_sm
and use the syntax
generate e+e- > h a [noborn=QED]
 you will compute the loop-induced process, and the code you get will let
you compute the xsection and generate events.
Note that this is different from
generate e+e- > h a [virt=QED]
for which you will just get the matrix element and a small wrapper code to
evaluate the ME in a single (or a bunch of) phase space point(s)
Hope this helps.
Best,

Marco

Dear Marco,

That is really great.
The only reason is the cross-section, which is really small.
Hope to discuss more if I will proceed further on the project.

Now can you give some tentative time when the Beamstrahlung will ready to
be used in MadGraph5 ?

we are actually working on it right now, but I can’t promise any time-scale for that
