A python interface to fortran code developed by Vadim A. Naumov and Konstantin Kuzmin, calculating neutrino-nucleon deep inelastic charged/neutral current cross-sections.
Project description
nudisxs
Table of Contents
Overview
The nudisxs package integrates Python with Fortran computational routines, offering a user-friendly interface for complex neutrino-nucleon interaction simulations. This includes both charged and neutral current exchange calculations.
Requirements
- LHAPDF. Install it with python support. Follow installation instructions. Installations to a custom place like
/foo/lhapdfrequires setup of three variables
export PATH=$PATH:/foo/lhapdf/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/foo/lhapdf/lib
export PYTHONPATH=$PYTHONPATH:/foo/lhapdf/lib/pythonX.Y/site-packages
Installation
Installing from PyPi
You can easily install nudisxs from PyPi using pip:
pip install nudisxs
Installing from Git
To install the latest development version directly from the repository:
git clone git@git.jinr.ru:dnaumov/nudisxs.git
cd nudisxs
python install .
Usage
Python Interface
The disxs.py module in nudisxs provides all necessary interfaces to the underlying Fortran code. This includes functions for initialization and calculation of cross-sections.
Initialization
Common initialization functions:
-
most used:
- init_neutrino()
- init_pdf()
- init_target()
-
for experts:
- init_masses()
- init_bend_factor()
- init_q2_min()
- init_abc()
- init_structure_functions()
- init_r_function()
- init_final_hadron_mass()
- init_fl_function()
- init_qc()
- double differential cross-sections
\frac{d^2\sigma}{dxdy}
are available as
disxs.xs_cc(e,x,y) for charged current exchange and
disxs.xs_nc(e,x,y) for neutral current exchange.
