tparton 0.1.18

Evolution of the transversity parton distribution functions via two methods: (1) direct integration of the DGLAP equations along the energy scale and (2) fast Mellin inversion.

tParton

This is an evolution code for the transversity parton distribution functions encountered in hadronic physics.

First, install this package using pip install tparton.

To evolve a transversity pdf, run the command python -m tparton m. This uses the Mellin moment by default. To use the energy scale integration method, run the command python -m tparton t. Use python -m tparton m -h or python -m tparton t -h for help.

An example run will look like:

python -m tparton m INPUTPDF.dat 3.1 10.6 --morp plus -o OUTPUTPDF.dat

We are evolving the INPUTPDF.dat from 3.1 to 10.6 GeV², for the plus type distribution, and with output written to OUTPUTPDF.dat.
