002703392 520__ $$9Springer$$aThe charge-conjugation and parity-reversal (CP) symmetry of fundamental particles is a symmetry between matter and antimatter. Violation of this CP symmetry was first observed in 1964$^1$, and CP violation in the weak interactions of quarks was soon established$^2$. Sakharov proposed$^3$ that CP violation is necessary to explain the observed imbalance of matter and antimatter abundance in the Universe. However, CP violation in quarks is too small to support this explanation. So far, CP violation has not been observed in non-quark elementary particle systems. It has been shown that CP violation in leptons could generate the matter–antimatter disparity through a process called leptogenesis4. Leptonic mixing, which appears in the standard model’s charged current interactions$^{5,6}$, provides a potential source of CP violation through a complex phase δCP, which is required by some theoretical models of leptogenesis$^{7,8,9}$. This CP violation can be measured in muon neutrino to electron neutrino oscillations and the corresponding antineutrino oscillations, which are experimentally accessible using accelerator-produced beams as established by the Tokai-to-Kamioka (T2K) and NOvA experiments$^{10,11}$. Until now, the value of δCP has not been substantially constrained by neutrino oscillation experiments. Here we report a measurement using long-baseline neutrino and antineutrino oscillations observed by the T2K experiment that shows a large increase in the neutrino oscillation probability, excluding values of δCP that result in a large increase in the observed antineutrino oscillation probability at three standard deviations (3σ). The 3σ confidence interval for δCP, which is cyclic and repeats every 2π, is [−3.41, −0.03] for the so-called normal mass ordering and [−2.54, −0.32] for the inverted mass ordering. Our results indicate CP violation in leptons and our method enables sensitive searches for matter–antimatter asymmetry in neutrino oscillations using accelerator-produced neutrino beams. Future measurements with larger datasets will test whether leptonic CP violation is larger than the CP violation in quarks.

002703392 520__ $$9arXiv$$aThe current laws of physics do not explain the observed imbalance of matter and antimatter in the universe. Sakharov proposed that an explanation would require the violation of CP symmetry between matter and antimatter. The only CP violation observed so far is in the weak interactions of quarks, and it is too small to explain the matter-antimatter imbalance of the universe. It has been shown that CP violation in the lepton sector could generate the matter-antimatter disparity through the process called leptogenesis. The quantum mixing of neutrinos, the neutral leptons in the Standard Model, provides a potential source of CP violation through a complex phase dCP, which may have consequences for theoretical models of leptogenesis. This CP violation can be measured in muon neutrino to electron neutrino oscillations and the corresponding antineutrino oscillations, which are experimentally accessible with accelerator-produced beams as established by the T2K experiment. Until now, the value of dCP has not been significantly constrained by neutrino oscillation experiments. Here the T2K collaboration reports a measurement that favors large enhancement of the neutrino oscillation probability, excluding values of dCP which result in a large enhancement of the observed anti-neutrino oscillation probability at three standard deviations (3 sigma). The 3 sigma confidence level interval for dCP, which is cyclic and repeats every 2pi, is [-3.41,-0.03] for the so-called normal mass ordering, and [-2.54,-0.32] for the inverted mass ordering. Our results show an indication of CP violation in the lepton sector. Herein we establish methods for sensitive searches for matter-antimatter asymmetry in neutrino oscillations using accelerator-produced neutrino beams. Future measurements with larger data samples will determine whether the leptonic CP violation is larger than the quark sector CP violation.

Subfigure \textbf{a} shows 2D confidence intervals at the 68.27\% confidence level (CL) for $\delta_{CP}$ vs $\sin^2\theta_{13}$ in the preferred normal ordering. The intervals labelled T2K only indicate the measurement obtained without using the external constraint on $\sin^2\theta_{13}$, while the T2K + Reactor intervals do use the external constraint. The star shows the best-fit point of the T2K + Reactors fit in the preferred normal mass ordering. Subfigure \textbf{b} shows 2D confidence intervals at the 68.27\% and 99.73\% confidence level for $\delta_{CP}$ vs $\sin^2\theta_{23}$ from the T2K + Reactors fit in the normal ordering, with the colour scale representing the value of negative two times the logarithm of the likelihood for each parameter value. Subfigure \textbf{c} shows 1D confidence intervals on $\delta_{CP}$ from the T2K + Reactors fit in both the normal (NO) and inverted (IO) orderings. The vertical line in the shaded box shows the best-fit value of $\delta_{CP}$, the shaded box itself shows the 68.27\% confidence interval, and the error bar shows the 99.73\% confidence interval. It is notable that there are no values in the inverted ordering inside the 68.27\% interval.

Distribution of the particle identification (PID) parameter used to classify Cherenkov rings as electron-like and muon-like. Events to the left of the blue line are classified as electron-like and those to the right as muon-like. The filled histograms show the expected number of single ring events after neutrino oscillations, with the first and last bins of the distribution containing events with discriminator values above and below the displayed range respectively. The vertical error bars on the data points are the standard deviation due to statistical uncertainty. The PID algorithm uses properties of the light distribution such as the blurriness of the Cherenkov ring to classify events. The insets show examples of an electron-like (left) and muon-like (right) Cherenkov ring.

Subfigure \textbf{a} (\textbf{b}) shows the reconstructed neutrino energy spectra for the SK samples containing electron-like events in neutrino(antineutrino)-mode beam running. The uncertainty shown around the data points accounts for statistical uncertainty. The uncertainty range is chosen to include all points for which the measured number of data events is inside the 68\% confidence interval of a Poisson distribution centred at that point. The solid stacked chart shows the predicted number of events for the $CP$-conserving point $\delta_{CP}=0$ separated according to whether the event was from an oscillated neutrino or antineutrino or from a background process. The dashed lines show the total predicted number of events for the two most extreme $CP$-violating cases. Subfigure \textbf{c} shows the predicted number of events for $\delta_{CP}=-\frac{\pi}{2}$ and the measured number of events in the three electron-like samples at SK. The predicted number of events is broken down into the same categories as subfigures \textbf{a} and \textbf{b} and the systematic uncertainty shown is after the near-detector fit. In both \textbf{a} and \textbf{b} for all predictions, normal ordering is assumed, and $\sin^2\theta_{23}$ and $\Delta m^2_{32}$ are at their best-fit values. $\sin^2\theta_{13}$, $\sin^2\theta_{12}$ and $\Delta m^2_{21}$ take the values indicated by external world average measurements~\cite{Tanabashi:2018oca}. The parameters accounting for systematic uncertainties take their best-fit values after the near-detector fit.

Reconstructed muon momentum in two of the ND280 CCQE-like event samples for both neutrino (subfigure \textbf{a}) and antineutrino (subfigure \textbf{b}) beam mode. The prediction with all parameters set to their best-fit value from a fit to the ND280 data is shown by the coloured histograms, split into true neutrino CCQE, antineutrino CCQE, neutral current (NC) and all other interactions. The dashed line shows the prediction before a fit to the ND280 data. The vertical error bars on the data represent the standard deviation due to statistical uncertainty. Subfigure \textbf{c} shows the ratio of the observed data to the best-fit prediction (MC) in both neutrino and antineutrino mode samples.
