Primordial Lithium Puzzle and the Axion Quark Nugget Dark Matter Model
read the original abstract
Astrophysics today faces a number of mysteries which defiant their resolutions in spite of drastic improvements in instrumental design, better technique being developed, and gradual improvements in theoretical and computation methods over last decades. Primordial Lithium Puzzle is known to stay with us for at least two decades, and it is very likely that its final resolution will require some fundamentally new ideas, novel frameworks and a non-conventional paradigms. We propose that Primordial Lithium Puzzle finds its natural resolution within the so-called Axion Quark Nugget (AQN) dark matter model. This model was invented long ago as a natural explanation of the observed ratio $\Omega_{\rm dark} \sim \Omega_{\rm visible}$ without any references to BBN physics. In this new paradigm, in contrast with conventional WIMP (Weakly Interacting Massive Particle) framework the dark matter (DM) takes the form of the macroscopically large quark nuggets without requiring any new fields beyond the standard model physics, except for the axion. The time evolution of these AQNs in primordial soup at $T\sim 20$ KeV suggests a strong suppression of the abundances of nuclei with high charges $Z\geq 3$. This suppression mechanism represents the resolution of the primordial lithium abundance within AQN dark matter scenario.

The Glow of Axion Quark Nugget Dark Matter: (IV) CMB Spectral and Anisotropy Signatures
Axion quark nugget dark matter would create a μ-type CMB spectral distortion near 6×10⁻⁸ with y near 2×10⁻⁹, detectable by proposed missions, while leaving CMB anisotropies essentially unchanged.
