Code and results for the production of chameleons in the Sun, as well as the detection rate of chameleons at XENON1T.
The key parts of the computation are:
- Calculation of the flux of chameleons per unit energy due to Primakoff effect at the tachocline
- Calculation of the cross section for the absorption of chameleons
- Monte Carlo analysis (see the montepython folder)
The script for generating plots from the results is in [code/ChameleonFlux.py]. The first thing to do is to edit [data_path = "../data/"] so that the directory variables point to the right place.
The montepython folder contains the MontePython likelihood we developed. More details are provided in the MontePython README, but in general we are assuming that you are familiar with MontePython!
