Beyond the Standard Model Submodules

Run SARAH models precompiled by the butler script of SARAH Toolbox.

TUTORIAL: SARAH talk at IPP-UFRN-Natal (Sept. 2019): http://bit.ly/SARAHIIP

WARNING! Clone with --recursive option in order to download the Toolbox submodles:

git clone --recursive [email protected]:restrepo/BSM-Submodules.git

To clone an specific model, check the associtated branch in the format: CATEGORY+MODEL (see below) and clone with

git clone --recursive -b CATEGORY+MODEL [email protected]:restrepo/BSM-Submodules.git
cd BSM-Submodules
./install.sh #Fast butler

Or try directly here:

Design

The rules to implement the fermion/scalars multiplets are in the files:

• SARAH/Models/blocks.fermions.lha
• SARAH/Models/blocks.scalars.lha

implemented as LHA blocks.

The master branch only contains the standard SARAH-Toolbox distribution plus the new generic files.

Each new model MODEL is build inside a CATEGORY under the branch:

CATEGORY+MODEL

based in the predefined blocks in the fermion/scalars multiplets files. Explore the branches!

Implemened CATEGORY's:

• SM: Explore SARAH feautures
• SimplifiedDM: Simplified Dark Matter Models
• radinert: Models with radiative neutrino masses and dark matter candidates with SM + Z2-odd particles
• B-L: $B-L$ models

Each implemented model have a notebook in BSM dir:

BSM/CATEGORY-MODEL.ipynb

with examples to run and scan the parameter space.

The module hep (in BSM/hep.py) used there, have the objects to automatically run the model in a similar way to the SSP SARAH-toolbox package.

See README_CREATES_NEW_MODEL.md to help with build new models. Send the new models as a pull request.

Updating submodules

External dependences are tried as git submodules. Each submodule, SBM, is update as follow

rm -rf SBM/*
wget http://....SBM_vN.N.tar.gz
tar -zxvf SBM_vN.N.tar.gz -C SBM --strip-components=1
cd SBM
find . -type d -empty -not -path "./.git/*" -exec touch {}/.gitkeep \;
git add .
git commit -am 'vN.N.N'
git push origin master

In addtion a tagged release is created in the SBM repo, or locally for some commit_HASH:

git tag -am "SBM-N.N.N.tar.gz" vN.N.N commit_HASH
git push origin vN.N.N

and saving the "Draft" in the releases of GitHub.

Switch to an specific tag

One specific tagged version, which is no necessarily a release, can be used after use:

git tag -l #list tags 
git checkout tags/v4.12.3 -b v4.12.3_branch

inside the specific submodule.

After some change in the official submodule repository at https://github.com/restrepo/sbm, to update all the submodules inside this repository (https://github.com/restrepo/BSM-Submodules), which add an specific tag each submodule, use the following sequence of git commands:

git pull --recurse-submodules
git submodule update --remote --recursive #Check changes in official sbm repo
git commit -am 'Updated Submodules tags'
git push origin master

Fix submodule tag

Tag is just an alias to an specific commit. We need to recover that commit, fix it creating a new branch, deleting the old tag, and creating a new tag but pointing to a commit inside that new branch

After clone a clean copy of the submodule, e.g. https://github.com/restrepo/SARAH, checkout to the specific tag

git checkout tags/v4.12.3 -b v4.12.3_branch

Make all the necessary fixes and push the changes to the new remote v4.12.3_branch branch.

Now, the old tag need to be deleted both locally an remotely and recreted with the last commit to that branch

git push origin --delete v4.12.3
git tag -d v4.12.3
git tag -a v4.12.3 2f1e527b
git push origin v4.12.3

Installation

Everything could be installed after the git clone. To choose an specific release version, e.g vN.N, of some submodule, go there and

git checkout -b vN.N

Finally, be sure to execute install.sh to compile the SPHENO, calchep and micromegas submodules

Debian 9 and related Linux distributions

Problems with the ar command

In Debian 9 there is bug which breaks backward compatibility of compilers. It is fixed by declaring a global variable for the ar command. For example, by adding to the ~/.bashrc file:

export ARFLAGS=rvU

Problems with C++ compiler

In the new version of the g++ compilers such as the one in Debian 9:

g++ (Debian 6.3.0-18) 6.3.0 20170516

we need to enforce the c++98 standard in order to compile the CalcOmega.cpp file of SARAH models in micrOMEGAS without errors.

It is done for example by changing the following line in ./micromegas/include/modelMakefile:

$(DLSET) $(CXX) $(CXXFLAGS)  -o $(main:.cpp=) $(main)  $(SSS)  $(lDL)  -lm -lpthread

to

$(DLSET) $(CXX) $(CXXFLAGS) -std=c++98 -o $(main:.cpp=) $(main)  $(SSS)  $(lDL)  -lm -lpthread

In addition, CalcOmega5.cpp must be modified for micrOMEGAS 5.0 which requires now a new argument in the darkOmega function.

$ diff CalcOmega.cpp CalcOmega5.cpp
14a15
>		int* Err;
25c26
<			Omega = darkOmega(&Xf,fast,Beps);
---
>			Omega = darkOmega(&Xf,fast,Beps,Err);

Official README stars here

This README file describes the contents and usage of the SUSY toolbox package.

1. Content

---

All file locations are relative to the package root.

• configure This is the compiled configuration script which is invoked by the user (see below).

• butler.in The input file which is translated into the butler script (see below) by configure.

• Makefile.in Translated into Makefile by configure.

• m4/* Files necessary for the automatic creation of aclocal.m4 via aclocal (NB: this is not necessary for ordinary usage).

• aclocal.m4 Autoconf helper macros required to create configure from configure.ac via autoconf, automatically generated from the contents of m4 by aclocal (NB: not necessary for ordinary usage).

• configure.ac The source which is translated into configure by autoconf (NB: not required for ordinary usage).

-tarballs The configure script will store any automatically fetched tarballs in this directory.

2. Description

---

The package is built around a configure shell script which is implemented using autoconf for enhanced portability. Note that the script is shipped ready to use, neither installation nor invocation of autoconf is required by the user (unless he/she wants to modify the script itself). The prerequisites to use the toolbox are

• Mathematica: mandatory as SARAH is a Mathematica program. Versions >= 5 will work.
• A FORTRAN compiler is required for Spheno, HiggsBounds, CalcHep, Micromegas and WHIZARD. gfortran is recommended and works fine for all programs (note that WHIZARD requires gfortran 4.5 or better).
• A C compiler is required for CalcHep and Micromegas (the GNU C compiler works fine).
• O'Caml and latex is required by WHIZARD and checked for during the WHIZARD configuration.
• wget or curl are required for automatic downloading of the package tarballs by configure.
• Make

In order to use the script, first create a directory in which the toolbox shall be set up. Change to this directory and invoke the configure script, e.g. via ../configure. The script will now proceed to check the prerequisites and download any required packages from the Internet. For WHIZARD, the WHIZARD configure script is invoked automatically.

If the default configuration is not sufficient, command line options can be used to disable a subset of packages (e.g. --disable-micromegas) or to configure the names and options of the compilers and the mathematica kernel (e.g. MATH=math_5.2). An exhaustive list of options can be obtained via the --help option.

Please note that the goal of this package is not to create modified forks of the various programs; therefore, the versions of the programs provided by the authors on the web and their various build systems are used. Unfortunately, this implies that the compiler settings don't automatically propagate to CalcHep and Micromegas which have rather convoluted build systems. Thus, any changes to the setup of those two packages have to be made by hand before running make.

On finalization, configure creates a Makefile and the butler script in the toolbox directory. Invoking make triggers the compilation and installation of the various packages by calling the respective build systems. Upon completion, the compiled packages can be found in there respective directories, with an additional unversioned symlink pointing to the versioned directory (e.g. SPHENO -> SPHENO-3.1.5). The only exception is WHIZARD which is installed directly into a directory called whizard.

For simple use cases, the butler script can be used to completely automate the implementation of a new model into the various packages, provided that the model is added to SARAH. The script is invoked using "butler modelname" and will first create the necessary model files using SARAH and then proceed to compile and add the model to the various packages. A list of the supported command line options can be obtained via "--help" or "-h" which includes options to disable individual packages (however, no packages disabled during configure can be enabled this way).

3. Troubleshooting

---

• Configure complains about missing prerequisites. Make sure that the corresponding programs are installed and working correctly.

• Errors in the build process of individual packages. Make sure that the necessary compilers are installed and working. Unfortunately, there is a limit on the influence which the toolbox script has over the build process of the individual packages, so it might be necessary to build the packages manually (in the directories where configure has untarred them) in order to solve uncommon build problems. After manual compilation, the toolbox make should go through, and butler will work as intended.

• Download and / or checksum failures. Make sure that your Internet connection is working properly and the download sites can be reached in a browser. If a checksum fails, the file might have been damaged during download. In this case, remove the file from the tarballs directory (see above) and retry. If this doesn't help (or if the download location has moved), please contact one of the toolbox authors.
