Sushanta:
- Problem with 4x too high yields was fixed
- The issue was, that the primordial fraction from neutrons and protons was very different, but the correction was applied to both equally, resulting in a too high yield
- This issued a discussion that the primordial fraction obtained from ThermalFIST should be varied and added to the final deuteron yields as a systematic
Maxi:
- continued working on argonne v18 wavefunction
- incidentally all the cross terms in the Wigner function are purely imaginary, even when removing the complex phases from the wave function
- there is a large dependence of the deuteron yield on the detailed fit of the wavefunction
- Bhawani mentioned that the large r behaviour of the wavefunction could have a large influence on the small q region (which is what is probed by coalescence)
- We need to be very careful with the fitting procedure including systematic variations
Bhawani:
- will do the argonne v18 calculation as well as a cross-check
