Description
The radiative proton capture on $^{15}\mathrm{N}$ reaction, $^{15}\mathrm{N}(p, \gamma)^{16}\mathrm{O}$, is the leading process that gives a path from the CN cycle to the NO cycle and, therefore, further types of the CNO cycle. In the present work, we study the $^{15}\mathrm{N}(p, \gamma)^{16}\mathrm{O}$ reaction in effective field theory. We construct the effective Lagrangian appropriate for this reaction at stellar energies and calculate the astrophysical S-factor. Furthermore, we determine the low-energy constants, resonance energies, and widths by fitting the empirical data of the S-factor at the range of $338 \ \mathrm{keV} < E_p < 1028 \ \mathrm{keV}$. Based on the obtained values of the parameters, we report an S-factor value for this reaction at extremely low energy, $S(E=0)$, and compare the results with that of the previous studies.
