Cross section problem

There is not such an option at the moment to evalate cross section as a function of the polarisation for several points.
We will implement it shortly and let you know

Thank you sir for your response. Sir is there is an option for cross
section vs coupling of trilinear self coupling in type I 2hdm?
Sir my second question is that if we use User define function so how we
create coupling of trilinear self coupling as User defined and how i find
distribution of cross section as a function of g_hhh
Thank you again for your response

I am sorry sir but you did not get my point i ask two questions.
1)polarization
2)coupling of trilinear higgs self coupling.
Sir now i want to construct the geaph of cross section as a function of
g_hhh(or lambda_hhh) so if there is an option for it please let me know and
if there is no option for it too then can i work on it using user defined
function.
Thank you for your time and quick response.

1) Polarisation

a) Take this file
https://www.dropbox.com/s/utsekj09ifsybd9/run_batch?dl=0

and replace run_batch file with this one in bin/ directory of your calchep installation

b) run

calchep_batch

with the batch file containing lines below
#############
Model: SM
Process: e%,E%->W+,W-
pol1: 0
pol2: pp2
p1: 100
p2: 100
Scan parameter : pp1
Scan begin : -0.5
Scan step size : 0.1
Scan n steps : 11
##########

and you will get the cross section for e+,e-->W+,W-
versus polarisation

You can run 2D scan also

2) coupling of trilinear higgs self coupling.

Add trilinear coupling to the list of model parameters,
run batch file with the scan statement and you will get cross section vs trilinear coupling

Hello Sir.
I tried on the run batch file can i find out the cross section as a
function of two independent polarization in which x axis represents
polarization of electron and y axis polarization of position using batch
file?

Yes sure,
it is straighforwar -- just use tw independent scans
for pp1 nd pp2, see below

#############
Model: SM
Process: e%,E%->W+,W-
pol1: pp1
pol2: pp2
p1: 100
p2: 100

Scan parameter : pp1
Scan begin : -0.5
Scan step size : 0.1
Scan n steps : 11

Scan parameter : pp2
Scan begin : -0.5
Scan step size : 0.1
Scan n steps : 11

##########

Thank you so much sir that solve my problem.

Thanks for your support but i have a question it takes 96 hours. Is it
normal? Or my laptop specifications are low. I have laptop core i5 having
8GB of RAM.
Is there any solution to to it?

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Do you still have your problem or it is solved?

yes sir. i want to add coupling in calchep parameter but i am unable to add
it according to calchep format

Hello Sir,
In the above batch file which scan give the polarization of electron and
which gives us the polarization of positron. kindly guide me sir

What do you mean under
"i want to add coupling in calchep parameter but i am unable to add
it according to calchep format" ?
Please clarify.
Which coupling and how you are trying to add?
Thanks,
Alexander

Hello Sir,
I want to add function of trilinear higgs self coupling (ghhh) in calchep
constraints and want to define a new variable.
My actual work is to calculate cross section as a function of ghhh/ghhh^sm.
Best regards
Muhammad Aamir

You said " i am unable to add it according to calchep format"
What did you do exactly and what did not work?
Alexander

In this file hhh function i want to add but get error about iota, charge of
electron and brackets

Please send me the model and the file,
I still have no idea what you are doing and whatis happening.
Send the model and modified file(s), please  to <email address hidden>

Hello Muhammad

your initial question unde this number was about polarisation and this question was addressed and solved.
So, please close this thread as solved,

For any new question, please use new number.

Thanks
Alexander

Thanks Alexander Belyaev, that solved my question.
