【摘要】：正Revised October 2013 by B.D.Fields.(Univ.of Illinois)P.Molaro(Trieste Observatory)and S.Sarkar(Univ.of OxfordNiels Bohr Institute.Copenhagen).Big-Bang nucleosynthesis(BBN)offers the deepest reliable probe of the early Universe,being based on well-understood Standard Model physics[1].Predictions of the abundances of the light elements.D.~3He,~4He,and~7Li,synthesized at the end of the'first three minutes'.are in good overall agreement with the primordial abundances inferred from observational data,thus validating the standard hot Big-Bang cosmology(see[2-4]for reviews).This is particularly impressive given that these abundances span nine orders of magnitude-from~4He/H~0.08 down to~7Li/H~10~(-10)(ratios by number).Thus BBN provides powerful constraints on possible deviations from the standard cosmology,and on new physics beyond the Standard Model[5-8].
