Interface for the CERN Yellow Report
Project description
About
yellowhiggs provides an interface with Higgs production cross section and branching ratio data in the CERN Yellow Report:
Automatic Installation
Automatically install the latest version of yellowhiggs with pip:
pip install --user yellowhiggs
or with easy_install:
easy_install --user yellowhiggs
Omit the --user for a system-wide installation (requires root privileges).
To upgrade an existing installation use the -U option in the pip or easy_install commands above.
Manual Installation
Get the latest tarball on PyPI
Untar and install (replace X appropriately):
tar -zxvf yellowhiggs-X.tar.gz cd yellowhiggs-X
To install yellowhiggs into your home directory if using at least Python 2.6:
python setup.py install --user
or with older Python versions:
python setup.py install --prefix=~/.local
You might need to first create the installation directory before executing the line above (for Python 2.4):
mkdir -p ~/.local/lib/python2.4/site-packages/
Usage
An example of how to use yellowhiggs:
>>> import yellowhiggs >>> >>> yellowhiggs.xsbr(7, 130, 'vbf', 'bb') (0.5689219999999999, 0.584851816, 0.555836794) >>> >>> yellowhiggs.xsbr(7, 130, 'vbf', 'tautau') (0.0632392, 0.0650098976, 0.06178469839999999) >>> >>> yellowhiggs.xsbr(7, 125, 'ggf', 'gammagamma') (0.0350599, 0.0418965805, 0.0297658551) >>> >>> yellowhiggs.xs(7, 150, 'vbf') (0.9617, 0.9895892999999999, 0.9405426) >>> >>> yellowhiggs.br(150, 'tautau') 0.0178 >>> yellowhiggs.br(155, 'tautau') 0.0105
Cross sections are returned in units of [pb].
xs returns the (central cross section, high value, low value) for a center-of-mass energy [TeV], Higgs mass [GeV], and production mode.
br returns the branching ratio for a Higgs mass [GeV] and decay channel.
xsbr returns the cross section times branching ratio for a center-of-mass energy [TeV], Higgs mass [GeV], production mode, and decay channel.
