SCANNING TANBETA IN FLOAT STEPS IN MADGRAPH

Asked by Eric Gyabeng Fuakye on 2019-05-29

Hello All,

I am trying to scan tangent beta in Madgraph using the 2HDM Type II Model.

I want my choice of range to be in steps of 0.29 which is a float, so I used the following syntax and got this error

set frblock 1 scan:range(1,30,0.29)

*******************************************************************************************
Command "generate_events run_02" interrupted with error:
TypeError : range() integer step argument expected, got float.
Please report this bug on https://bugs.launchpad.net/mg5amcnlo
More information is found in '/home/eric/MG5_aMC_v3_0_0/bin/DAMN_II/run_02_tag_1_debug.log'.
Please attach this file to your report.
********************************************************************************************
I guess this means I should set my steps in integers and not float. I will be glad if anyone can give an idea on solivng this error.
Thanks

Hi,

indeed the range function does not take float argument in python.

But you can use comprehension list something like

> set frblock 1 scan:[ 1+0.29*i for i in range(100) if 1+0.29*i< 30]

Cheers,

Olivier
