Abstract
The forthcoming Jiangmen Underground Neutrino Observatory (JUNO) is planned to resolve the neutrino mass ordering. However, given its energy resolution capability
and detector volume, the JUNO detector can
be used to test various new physics predictions. Among numerous new physics, this work is dedicated to scrutinizing the 5.49 MeV solar axions flux, which would be produced, in the $p(d, ^3{\rm He})a$ nuclear reaction. For axion detection, we adopt various processes such as Compton and inverse Primakoff conversion, along with their decay into two photons or electron-positron pairs inside the detector.
We perform a likelihood analysis in order to forecast the JUNO's sensitivity. To make a comprehensive study, the sensitivity limit
arising from various other experiments has also been conferred.
