TL;DR Summary
Any help how to find the right value of the baryon asymmetry or the baryon density expected from the Big Bang Nucleosynthesis (BBN) of order ##\sim 10^{-10}## in a paper
I'm trying to understand from this paper

https://pdg.lbl.gov/2020/reviews/rpp2020-rev-bbang-nucleosynthesis.pdf

What is the value of the baryon to photon ratio ##\eta=n_b/n_\gamma## as named in figure 24.1, but I can't get from the figure or the paper how ##\eta## is of order ##10^{-10}##

Any help in reading such papers?

I mean I found in another study that the value of ##\eta## as expected from BBN is of order: ##6.07\pm0.33 \times 10^{-10} ##

So where can we find such value in the mentioned paper?

That's a review. It's job is to summarize and point you to the references. To understand the details, read the references.

I was reading a study about baryogenesis and the authors cited the mentioned paper and its ##\eta## value, so I just wonder how they concluded this value

It literally briefly mentions how things are done and give you the references to where the details can be found.

Well, I'm simulating a neutron-proton scattering phase shift. The equation that I solve numerically is the Phase function method and is $$ \frac{d}{dr}[\delta_{i+1}] = \frac{2\mu}{\hbar^2}\frac{V(r)}{k^2}\sin(kr + \delta_i)$$ ##\delta_i## is the phase shift for triplet and singlet state, ##\mu## is the reduced mass for neutron-proton, ##k=\sqrt{2\mu E_{cm}/\hbar^2}## is the wave number and ##V(r)## is the potential of interaction like Yukawa, Wood-Saxon, Square well potential, etc. I first...
