Primordial lithium abundance in catalyzed big bang nucleosynthesis

  author={Christina Marie Bird and Kristen Koopmans and Maxim Pospelov},
  journal={Physical Review D},
There exists a well-known problem with the {sup 7}Li+{sup 7}Be abundance predicted by standard big bang nucleosynthesis being larger than the value observed in population II stars. The catalysis of big bang nucleosynthesis by metastable, {tau}{sub X} > or approx. 10{sup 3} sec, charged particles X{sup -} is capable of suppressing the primordial {sup 7}Li+{sup 7}Be abundance and making it consistent with the observations. We show that to produce the correct abundance, this mechanism of…

SUSY-catalyzed big bang nucleosynthesis as a solution of lithium problems

6Li abundances observed in metal-poor stars appear to exhibit a plateau as a function of metallicity similar to that for 7Li. This suggests a big bang origin for 6Li. However, since the radiative

Destruction of {sup 7}Be in big bang nucleosynthesis via long-lived sub-strongly interacting massive particles as a solution to the Li problem

We identify reactions which destroy $^{7}\mathrm{Be}$ and $^{7}\mathrm{Li}$ during big bang nucleosynthesis (BBN) in the scenario of BBN catalyzed by a long-lived sub-strongly-interacting massive

A Solution to Lithium Problem by Long-Lived Stau

We review a non-standard Big-Bang nucleosynthesis (BBN) scenario within the minimal supersymmetric standard model, and propose an idea to solve both ${}^{7}$Li and ${}^{6}$Li problems. Each problem

Effect of Long-lived Strongly Interacting Relic Particles on Big Bang Nucleosynthesis

It has been suggested that relic long-lived strongly interacting massive particles (SIMPs, or X particles) existed in the early universe. We study effects of such long-lived unstable SIMPs on big

Big Bang nucleosynthesis with long-lived strongly interacting relic particles

Abstract We study effects of relic long-lived strongly interacting massive particles (X particles) on big bang nucleosynthesis (BBN). The X particle is assumed to have existed during the BBN epoch,

Catalyzed Big Bang Nucleosynthesis and the Properties of Charged Relics in the Early Universe

The existence of charged electroweak-scale particles in the early universe can drastically affect the evolution of elemental abundances. Through the formation of Coulombic bound states with light

Metastable GeV-scale particles as a solution to the cosmological lithium problem

The persistent discrepancy between observations of {sup 7}Li with putative primordial origin and its abundance prediction in big bang nucleosynthesis has become a challenge for the standard

Big bang nucleosynthesis (BBN) theory, together with the precise WMAP cosmic baryon density, makes tight predictions for the abundances of the lightest elements. Deuterium and 4He measurements agree

The synthesis of {sup 6}Li during the epoch of big bang nucleosynthesis due to residual annihilation of dark matter particles is considered. By comparing the predicted {sup 6}Li to observations of

Big bang nucleosynthesis with long-lived charged massive particles

We consider big bang nucleosynthesis (BBN) with long-lived charged massive particles. Before decaying, the long-lived charged particle recombines with a light element to form a bound state like a

Particle physics catalysis of thermal big bang nucleosynthesis.

In particle physics models where subsequent decay of X- does not lead to large nonthermal big bang nucleosynthesis effects, this directly translates to the level of sensitivity to the number density of long-lived X- particles relative to entropy of nX-/s less, which is one of the most stringent probes of electroweak scale remnants known to date.

Li 6 production by the radiative decay of long-lived particles

Recent spectroscopic observations of metal-poor stars have indicated that both $^{7}\mathrm{Li}$ and $^{6}\mathrm{Li}$ have abundance plateaus with respect to the metallicity. Abundances of
