Question

Could baryon asymmetry be negative?

Answer 1

it can be seen from expressions (9a, 9b,9c) that barygon asymmetry is proportional to negative lepton asymmetry. But in a model where leptogensis is generated and L >0, we get negative B. But this contradicts observation. Many pape

Answer 2

asymmetry is proportional to negative lepton asymmetry. But in a model where leptogensis is generated and L >0, we get negative B. But this contradicts observation. Many papers I read seem not to elaborate on this point.

I am confused about this result and interpretation.
