CP and T Trajectory Diagrams for a Unified Graphical Representation of Neutrino Oscillations
نویسندگان
چکیده
Recently the CP trajectory diagram was introduced to demonstrate the difference between the intrinsic CP violating effects to those induced by matter for neutrino oscillation. In this paper we introduce the T trajectory diagram. In these diagrams the probability for a given oscillation process is plotted versus the probability for the CPor the T-conjugate processes, which forms an ellipse as the CP or T violating phase is varied. Since the CP and the T conjugate processes are related by CPT symmetry, even in the presence of matter, these two trajectory diagrams are closely related with each other and form a unified description of neutrino oscillations in matter.

A tool for pictorial representation of CP and matter effects in neutrino oscillations —
We introduce “CP trajectory diagram in bi-probability space” as a powerful tool for pictorial representation of the genuine CP and the matter effects in neutrino oscillations. Existence of the correlated ambiguity in a determination of CP violating phase δ and the sign of ∆m213 is uncovered. Principles of tuning beam energy for a given baseline distance are proposed to resolve the ambiguity and...
متن کاملCP Violations in Lepton Number Violation Processes and Neutrino Oscillations
We examine the constraints on the MNS lepton mixing matrix from the present and future experimental data of the neutrino oscillation and lepton number violation processes. We introduce a graphical representation of the CP violation phases which appear in the lepton number violation processes such as neutrinoless double beta decay, the μ− − e+ conversion, and the K decay, K− → π+μ−μ−. Using this...
متن کاملNeutrino Mixing , Cp / T Violation and Textures in Four - Neutrino Models
We examine the prospects for determining the neutrino mixing matrix and for observing CP and T violation in neutrino oscillations in four-neutrino models. We focus on a general class of four-neutrino models with two pairs of nearly degenerate mass eigenstates separated by approximately 1 eV, which can describe the solar, atmospheric and LSND neutrino data. We present a general parametrization o...

متن کاملPossible new source of T and CP violation in neutrino oscillations
A model is presented to illustrate that vacuum neutrino oscillations can be essentially T and CP invariant up to a certain energy but strongly T and CP noninvariant at much higher energies. Detailed model results for the vacuum probabilities P (νμ → νe) and P (νe → νμ) are given, which may be relevant to proposed long-baseline neutrino-oscillation experiments.
