Abstract
The pion-less effective field theory has been used to study the \(^{3}H(\alpha ,\gamma )^{7}Li\) reaction using the Faddeev equation procedure. This reaction is the seventh interaction in the Big Bang Nucleosynthesis (BBN) model which has a golden role in the estimating of \(^{7}Li\) abundance in the universe, and answering the “cosmological lithium problem”. In this work the astrophysical s-factor of the \(^{3}H(\alpha ,\gamma )^{7}Li\) reaction has been calculated in leading order (LO), considering the Coulomb interactions, for the dominant electrical \(E_{1}\) transition from the s-and p-wave initial states to the final ground state of \(^{7}Li\), at the astrophysical range of \(E\leq 1.5\) MeV.
