# fiatlux
API for LUXqed methodology in global PDF fits.
[](https://zenodo.org/badge/latestdoi/113965474)
## Project summary and aim
The aim of `libfiatlux` is to provide a blackbox tool which computed the photon PDF at a given Q value
using the LUX approach by Manohar, Nason, Salam and Zanderighi in [arXiv:1607.04266](https://arxiv.org/abs/1607.04266) and [arXiv:1708.01256](https://arxiv.org/abs/1708.01256). The output of this repository is a C++ library
which can be imported and shared to other programs.
The library implements following features:
- Computes LUX photon by subdividing in elastic, inelastic and msbar components
- Allow variations of parameters to estimate uncertainties
- Generic interface to F2, FL and alpha QED: you can plug APFEL or any other evolution code.
### Release and Tag policy
The library is tagged and released when a major and stable status is achieved.
### Testing
Manual testes are available in the `examples` folder.
## Installation
### Python library
```Shell
pip install .
```
### C++ library
`libfialux` depends on the following libraries:
- pkg-config
- yaml-cpp
optinally to build the examples:
- lhapdf
- apfel
please ensure to have the dependencies correctly installed and in your PATH before installing libfiatlux.
#### Configurations
Possible configurations:
```Shell
cmake .
```
or (recommended):
```Shell
mkdir build
cd build
cmake ..
```
You can control the optional flags with `ccmake` or from cmd line, the most relevant flags are:
```Shell
CMAKE_INSTALL_PREFIX
ENABLE_EXAMPLES
```
On the command line, options are controlled appending a `-D` flag. For
example:
```
cmake .. -DENABLE_EXAMPLES=on
```
## Documentation
### Code documentation
The code is documented with Doxygen (folder doc/), if you find methods or classes not fully documented open a issue request.
