Evidence for leptonic CP phase from NO$\nu$A, T2K and ICAL: A chronological progression

Understand

We study the synergy between the long-baseline (LBL) experiments NO$\nu$A and T2K and the atmospheric neutrino experiment ICAL@INO for obtaining the first hint of CP violation in the lepton sector.

• We also discuss how precisely the leptonic CP phase ($\delta_{CP}$) can be measured by these experiments.
• The CP sensitivity is first described at the level of oscillation probabilities, discussing its dependence on the parameters -- $\theta_{13}$, mass hierarchy and $\theta_{23}$.
• In particular, we discuss how the precise knowledge or lack thereof of these parameters can affect the CP sensitivity of LBL experiments.
