Contents

• helplot.py - Python module with definition of primitives
• b2dstmunu_hel.py - Example of helicity angles diagram in B->Dstar mu nu decays
• b2dstdspi_dstpi_hel.py - Example of helicity angles diagram in B->Dstar Ds pi decays via the resonance in Dstar pi channel
• b2dstdspi_dspi_hel.py - Example of helicity angles diagram in B->Dstar Ds pi decays via the resonance in Ds pi channel

Requirements

python, numpy, scipy and matplotlib.

latex for LaTeX labels.

The environment can be set up with conda by
