The plots inside this repository ("C7_C7p.pdf" and "C7_C7p_BR_separately.pdf") show the constraints on the Wilson coefficients C7 and C'7, derived from several fits that include different combinations of observables.
The notebook "Numerics for constraints on C7 and C7p.ipynb" can be used to generate the data file "data.p", which is used by the notebook "Plots of constraints on C7 and C7p.ipynb" to generate the plots.
All of this is based on compagnion scripts to the paper arXiv:1608.02556 by Ayan Paul and David M. Straub.
The numerics is based on flavio.
