Documentation for "Method used for two-loop calculation"

[RobertoFranceschini]

Hello
I am sorry if this has been discussed before and I missed it in my search, but where exactly is documented what the different settings of "Method used for two-loop calculation" do? (Block SPhenoInput entry n.8)
Thanks a lot for the info!
Roberto


PS
I understand it is a very tough job, but let me point out that Pythia has managed to provide documentation for nearly all options (and are many!) via pretty convenient html document http://home.thep.lu.se/~torbjorn/pythia ... lcome.html that documents the physics of each setting in a pretty transparent and searchable way. Most important of all it provides a "one stop shopping" to learn what the code does if you set something to a different value. May I remark that SPheno documentation appear a bit too scattered around to 1) find where the option you need to learn about is documented 2) to be sure you are reading the latest version of that. That said the flexibility of SARAH+SPheno is admirable, but, as a user, to keep up with that one need good doc. The forum may help but is very heavy on both sides. In case such a "one stop shopping" for SARAH and SPheno exists, please disregard my comment and thanks a lot for pointing me to that help page.

Hi Roberto,

yes, there are many different references for SARAH/SPheno on arxiv. Therefore, I tried to collect everything on a wiki page: http://stauby.de/sarah_wiki/

The information you are looking for is (hopefully) given here:

Hi Florian, thanks a lot for pointing to these wiki pages, they look very useful and promising.

I notice that some images (for display math I guess) are actually broken links, anything that can be fixed?

Thanks again. All the best,
Roberto

Hi,

hm.. there are not hard links but the math is generated dynamically using a wiki plugin. If that doesn't show up correctly for you, it might be a server problem. On which page did you encounter such a problem?

Cheers,
Florian
