Description

We use the JUNO experiment which is a reactor neutrino experiment to constrain the parameters of the Large Extra Dimension (LED) model. The parameters of this model are the radius of extra dimension $R_{LED}$ and the lightest neutrino mass $m_0$. We select the JUNO experiment because its aims is to determine the hierarchy of the neutrino masses and for this it will simultaneously measure the oscillations due to the parameters $\mathrm{\Delta }{m}_{21}^2$ and $|\mathrm{\Delta }{m}_{32}^2|$ and also the mixing angles ${\theta }_{12}$ and ${\theta }_{13}$ using a resolution on the visible energy of the positrons of $1\mathrm{\%}$ at 1 MeV. The LED model used in this work considers that neutrinos are Dirac neutrinos, the space-time structure of our universe is 4 + 1 that is: four flat spatial dimensions where the extra spatial dimension is compactified in a circle of radius $R_{LED}$ and the 1 indicates a time dimension. We expect the results obtained in the parameters $R_{LED}$ and $m_0$ from this analysis will be slightly more restrictive than previous work already done due to the energy resolution of the JUNO experiment.
