Optimal time decay rates for the compressible Navier-Stokes system with and without Yukawa-type potential

Electronic Journal of Differential Equations, 2020
We consider the time decay rates of smooth solutions to the Cauchy problem for the compressible Navier-Stokes system with and without a Yukawa-type potential.

Decay rate changes in radioactive gamma emission as affected by 18 MeV proton cyclotron [PDF]

Nuclear Technology and Radiation Protection
Previous efforts to investigate changes in the decay constants of radioactive nuclides discovered that solar flares can temporarily alter radioactive decay rates.

Total decay rates of B mesons at NNLO-QCD

Journal of High Energy Physics
We update the Standard Model (SM) predictions for the lifetimes of the B +, B d and B s mesons within the heavy quark expansion (HQE), including the recently determined NNLO-QCD corrections to non-leptonic decays of the free b-quark.

Evidence for Solar Influences on Nuclear Decay Rates

, 2010
Recent reports of periodic fluctuations in nuclear decay data of certain isotopes have led to the suggestion that nuclear decay rates are being influenced by the Sun, perhaps via neutrinos.

Combination of Colour Favoured and Colour [PDF]

Journal of Sciences, Islamic Republic of Iran, 2008
In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in
