Description

ESSnuSB is a proposed future accelerator based experiment in Sweden to study neutrino oscillation. The main aim of this experiment is to measure the leptonic CP phase $\delta_{\rm CP}$ by probing the second oscillation maximum. The other future long-baseline experiments which will also study the phenomenon of neutrino oscillations are T2HK in Japan and DUNE in USA which . Apart from measuring the oscillation parameters, these experiments are also capable to test the viability of different theoretical models which predict the values of $\delta_{\rm CP}$ and other oscillation parameters. Two examples of such theories are flavour symmetry models and theories arising from modular symmetries. In this presentation, first I will give an overview of the ESSnuSB and the other neutrino experiments and then discuss the capability of these experiments to constrain the parameter space of a set of lepton flavour models and theories arising from modular symmetries.
