Overview of ESSnuSB experiment to measure $\delta_{CP}$

Abstract

In this proceeding we will present the capability of the ESSnuSB experiment to measure leptonic CP phase $\delta_{CP}$. In particular we will study: (i) sensitivity for different baseline options, (ii) the effect of systematic errors and (iii) optimisation of the neutrino to antineutrino run ratio. In addition we will also discuss a comparative analysis between ESSnuSB and T2HK pointing out the physics differences between these two experiments in measuring $\delta_{CP}$.
