Recent Wilkinson Microwave Anisotropy Probe (WMAP) measurements have determined the baryon density of the Universe {omega}{sub b} with a precision of about 4%. With {omega}{sub b} tightly constrained, comparisons of Big Bang nucleosynthesis (BBN) abundance predictions to primordial abundance observations can be made and used to test BBN models and/or to further constrain abundances of isotopes with weak observational limits. To push the limits and improve constraints on BBN models… Expand
Direct and Indirect Measurements for a Better Understanding of the Primordial Nucleosynthesis
The Big Bang Nucleosynthesis (BBN) model is a great success of nuclear astrophysics due to the outstanding agreement between observational and predicted light elements abundances. One exception,Expand
Low-energy d+d fusion reactions via the Trojan Horse Method
Abstract The bare nucleus S ( E ) factors for the H 2 ( d , p ) H 3 and H 2 ( d , n ) He 3 reactions have been measured for the first time via the Trojan Horse Method off the proton in 3He from 1.5Expand
Bayesian estimation of thermonuclear reaction rates for deuterium+deuterium reactions
The study of d+d reactions is of major interest since their reaction rates affect the predicted abundances of D, 3He, and 7Li. In particular, recent measurements of primordial D/H ratios call forExpand
Standard big bang nucleosynthesis and primordial CNO abundances after Planck
Primordial or big bang nucleosynthesis (BBN) is one of the three historical strong evidences for the big bang model. The recent results by the Planck satellite mission have slightly changed theExpand
A new tension in the cosmological model from primordial deuterium?
Recent measurements of the D(p,$\gamma)^3$He, nuclear reaction cross-section and of the neutron lifetime, along with the reevaluation of the cosmological baryon abundance from cosmic microwaveExpand
The Underground Nuclear Astrophysics in the Precision Era of BBN: Present Results and Future Perspectives
The abundance of light isotopes such as D, 3He, 4He, 6Li and 7Li produced during Big Bang Nucleosynthesis (BBN) only depends on particle physics, baryon density and relevant nuclear processes. At BBNExpand
The cross sections of the 2H(d,p)3H and 2H(d,n)3He reactions have been measured via the Trojan Horse method applied to the quasi-free 2H(3He,p 3H)1H and 2H(3He,n 3He)1H processes at 18 MeV off theExpand
Low-energy d+d fusion via the Trojan Horse Method
The 2H(d,p)3H and 2H(d,n)3He reactions have been recently investigated from Edd=1.5 MeV down to 2 keV, by means of the Trojan Horse Method (THM) applied to the Quasi Free 3He+d interaction at 18 MeVExpand
Differential and total cross sections and astrophysical S-factors for 2H(d,n)3He and 2H(d,p)3H reactions in a wide energy range
Abstract Differential cross sections of deuteron–deuteron fusion reactions are needed in astrophysics, precision cosmology, nuclear physics, and controlled nuclear fusion research. NewExpand
Bare nucleus S(E) factor of the 2H(d,p)3H and 2H(d,n)3He reactions via the Trojan Horse Method
The Trojan Horse Method was applied for the first time to the 2H(d,p)3H and 2H(d,n)3He reactions by measuring the 2H(3He,p3H)1H and 2H(3He,n3He)1H processes in quasi free kinematics. The 3He+dExpand
