PROSPINO2

You are looking at the new Prospino2 home page. Prospino2 is a computer program which computes next-to-leading order cross sections for the production of supersymmetric particles at hadron colliders. The processes currently included are squark, gluino, stop, neutralino/chargino, and slepton pair production. We have also included the associated production of squarks with gluinos and of neutralinos/charginos with gluinos or squarks and most recently leptoquark pair production. This list is likely to be expanded, please come back and check. If you are interested in our so-called propaganda plots showing a sample of Prospino results, there are an LHC version and a Tevatron version available.

This computer code is based on different projects with work done by many people over a long time - credits go to Wim Beenakker, Roland Höpker, Michael Krämer, Michael Spira and Peter Zerwas (in alphabetical order). The physics results are usually published, so you can cross check the results you get. As far as referencing goes, we will not publish a complete Prospino2 manual, because there are physics papers available for all processes. Instead, we would like you to reference the published papers for the respective processes. You can find a list of these papers below.

There has been a Fortran77 version of Prospino availabe for several years. The increased number of processes and the more complex set of input parameters have made it more convenient to migrate to Fortran90. The new code should run with any F90 compiler - for example the free gfortran, which even runs on your Macs. I have also tested the code with the F90 or F95 compilers by Intel, DEC, Portland Group and most recently NAG, where the latter was a serious pain.

Prospino2 can easily be linked to C++ programs, reads the Les Houches SUSY spectrum files and includes a set of easily accessible interfaces. Here you can see how a simple Prospino2 call looks. And this is the output for example for the SPS1a parameter point. For those of you who do not only want to produce supersymmetric particles, but also decay them again: you might be interested in the public code Sdecay, which can talk to Prospino2 through the Les Houches Accord.

There is now a second version of Prospino2.1. which allows you to treat the sbottom channels differently (in analogy to the stops). With the new version there are also switches to compute the combined renormalization/factorization scale varation and allow for non-mass-genenerate light-flavor squarks.

Good luck, enjoy working with our program, please give me some feedback, and - hey - do us the favor and discover supersymmetry some time, if it is not too much trouble
