Coulomb screening and weak interactions in a hot, magnetized plasma are investigated. Coulomb screening is evaluated in a relativistic thermal plasma in which electrons and positrons are in equilibrium. In […]
Previous studies of the reaction 3He+4He→7Be+γ have mainly focused on providing the best central value and error bar for the S factor at solar energies. Experimental measurements of this capture […]
Electron-positron annihilation largely occurs in local thermal and chemical equilibrium after the neutrinos fall out of thermal equilibrium and during the big bang nucleosynthesis (BBN) epoch. The effects of this […]
It has been speculated for a long time that neutrinos from a supernova (SN) may undergo fast flavor conversions near the collapsed stellar core. We perform a detailed study of […]
