- The discovery of neutrino oscillations unequivocally established that neutrinos possess mass and mix, thereby necessitating an extension of the Standard Model of particle physics. A crucial, yet unmeasured, parameter in the leptonic mixing matrix is the Dirac CP violating phase, $delta_{CP}$. Its non-zero value would imply charge-parity violation in the lepton sector, offering a potential explanation for the observed baryon asymmetry of the universe through leptogenesis. This paper explores the theoretical framework and experimental strategies aimed at unveiling the leptonic CP phase through precision measurements of neutrino oscillation asymmetries. We critically review the current status of experimental efforts, highlighting the pivotal role of long-baseline and dual-baseline neutrino experiments in disentangling the CP phase from other oscillation parameters and matter effects. The methodology involves analyzing flavor transition probabilities for both neutrinos and antineutrinos, focusing on the differences that are sensitively dependent on $delta_{CP}$. We discuss the anticipated sensitivities of next-generation experiments, detailing how advancements in neutrino beam technology and detector capabilities are poised to provide definitive evidence for or against leptonic CP violation. The implications of precisely determining $delta_{CP}$ extend beyond neutrino physics, impacting our understanding of fundamental symmetries, early universe cosmology, and guiding new theoretical frameworks beyond the Standard Model.
