A spectator scalar field coupled to the inflaton and to spacetime curvature yields a first-order correction to the baryon asymmetry in spontaneous baryogenesis, potentially enhancing it by orders of magnitude for small coupling g.
Since ϕ2 1 + ϕ2 2 is positive, the corrective term sign completely depends on the sign of ξ

Impact of a complex scalar spectator field on baryon asymmetry within spontaneous baryogenesis
A spectator scalar field coupled to the inflaton and to spacetime curvature yields a first-order correction to the baryon asymmetry in spontaneous baryogenesis, potentially enhancing it by orders of magnitude for small coupling g.
