Solid line: mass spectrum of primordial BHs for the parameter values: 𝑐₅=8.9⋅10¹², 𝑐=5.6⋅10⁻⁶𝐻⁻², 𝑑=5, 𝑏₁=12.89⋅10⁻⁶𝐻⁻⁴, 𝑏₂=−8⋅10⁻⁸𝐻⁶, 𝑐₁=2𝐻⁻², 𝑐_𝑉=−50𝐻⁻², Λ=0.0125𝐻², 𝜒₀=1.069⋅10⁷𝐻, 𝜈[𝑑]=10³, and 𝑚_𝐷=4.4⋅10⁴𝐻. The spectrum of the PBHs is very sensitive to the initial conditions, so that slight change of 𝜒 (in order of 10⁻⁵𝐻) drastically changes the picture (dashed and dot-dashed lines).
