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
