Cross section problem

Asked by Muhammad Aamir

Hello sir.
In calcHEP how we construct the graph of cross section as a function g_HHH/gHHH^SM for hhvvbar and zhh in the final state at 3 TeV center of mass energy of CLIC. sir here i use two h because i use 2HDM type 1.

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

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?

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.

We have
Process: e%,E%->W+,W-

and

pol1: pp1
pol2: pp2

pol1 is for the First particle, i.e. for e% (electron)
and
pol2 is for the Second particle, i.e. for E% (positron)
