#### Description

HpT-MON (Higgs pt-distribution in Momentum and N-space) computes the

transverse momentum distribution of the Higgs boson in `pp` collisions

at LO and NLO both in momentum and Mellin space.

#### Install dependencies

For the compilation, the code relies on [meson](https://mesonbuild.com/)

and [ninja](https://ninja-build.org/). To install meson and ninja, just run: 

```bash

pip install -r requirements.txt

```

In addition, `HpT-MON` relies on third party libraries:

* [CUBA](http://www.feynarts.de/cuba/): for the Monte Carlo integration. If

  Cuba is not installed yet on the system, run the following:

  ```bash

  source install-cuba.sh

  ```

* [YAML-cpp](https://github.com/jbeder/yaml-cpp): for the parsing of the input

  run card. If it is not installed in the system (make sure that duplicate

  installations are not present as this might results in an error), run:

  ```bash

  source install-yaml.sh

  ```

#### Compile & run the code

Thanks to meson, compiling the code is straightforward:

```bash

meson setup builddir

cd builddir

meson compile

```

This will generate two executables called `higgsfo-pt` and `higgsfo-n` in the `builddir` 

directory. To run the code, use one of the run cards in the `runcards` folder as follows:

```bash

./higgsfo-n ../runcards/Higgs-FO-as-N.yaml    (for results as a function of N)

./higgsfo-pt ../runcards/Higgs-FO-as-pt.yaml  (for results as a function of pt)

```

Every time changes are made, the code can be re-compiled by just running `meson compile`

inside the `builddir` directory.

#### System-wide installation

Finally, in case one wants to install the header files and library system-wide, this

can be done by running the following:

```bash

meson install

```

This, by default, will install the header files in `/{prefix}/include/higgs-fo` and

add `higgsfo.pc` to the PKG path.

```python
