yellowhiggs 1.0a1

Interface for the CERN Yellow Report

About

yellowhiggs provides an interface with Higgs production cross section and branching ratio data in the CERN Yellow Report:

• CERNYellowReportPageAt7TeV

• CERNYellowReportPageBR

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

Usage

An example of how to use yellowhiggs:

>>> import yellowhiggs
>>>
>>> yellowhiggs.xsbr(130, 'vbf', 'bb')
(0.5689219999999999, 0.584851816, 0.555836794)
>>>
>>> yellowhiggs.xsbr(130, 'vbf', 'tautau')
(0.0632392, 0.0650098976, 0.06178469839999999)
>>>
>>> yellowhiggs.xsbr(125, 'ggf', 'gammagamma')
(0.0350599, 0.0418965805, 0.0297658551)
>>>
>>> yellowhiggs.xs(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 given Higgs mass [GeV] and production mode. br returns the branching ratio at a given Higgs mass [GeV] for a decay channel. xsbr returns the cross section times branching ratio for a given Higgs mass [GeV], production mode and decay channel.
