Study of the 7Be(d,3He)6Li* reaction at 5 MeV/u

Physics Letters B
The measurement of the 7Be(d,3He)6Li* transfer cross section at 5 MeV/u is carried out. The population of the 2.186 MeV excited state of 6Li in this reaction channel is observed for the first time.

Improved constraints on the variation of the weak scale from Big Bang nucleosynthesis

Journal of High Energy Physics
We present an improved calculation of the light element abundances in the framework of Big Bang nucleosynthesis as a function of the Higgs vacuum expectation value v. We compare the methods of our calculation to previous literature including the recently
