Is it possible to generate matrix elements for tree level diagrams at quadruple precision?

Asked by oleh

Dear MadGraph experts,

I would like to generate matrix elements for some 2 to 4 processes at quadruple level of precision using "output standalone" command.
I am interested only in tree level diagrams. Is there any possibility to do it automatically ?

With best regards,
Oleh

Hi,

We do not have any output mode for this.
I guess that you can define a plugin to define such kind of output.

Since we are already doing computation in quadruple computation for the loop-computation, everything should be kind of ready in the code to output the tree-level in quadruple precision.
It is a just of taking the time to modify the double precision computation and call the quadruple version
of converters (and change template to have them in quadruple/...)

Cheers,

Olivier
