The Super-Kamiokande experiment (Super-K) is a water Cherenkov detector noted for its discovery of the oscillation of atmospheric neutrinos. The dominant effect of the oscillation of muon neutrinos in the atmosphere is the appearance of tau neutrinos. Direct detection of ν τ in the atmospheric neutrino flux would provide a clear confirmation of neutrino oscillations. The sub-dominant ν µ oscillation mode, of ν µ changing to ν e , is studied at Super-K to determine mass ordering. Currently, ν τ interactions form the biggest background to the mass ordering signal in the Super-K analysis. Machine learning techniques of neural networks are used at Super-K to segregate ν τ charged-current interactions from the interactions of the atmospheric muon and electron neutrinos. 10% more events can be added to the analysis by expanding the fiducial volume of the detector. Studies on the Monte-Carlo simulations for a Super-K run period, between 2008 to 2018, suggest that we can expect improvements in the search for tau neutrinos and the suppression of mass-ordering backgrounds.

We analyze invisible decay of neutrinos in the presence of oscillation and matter effects. The inclusion of decay can be accommodated by a non-Hermitian effective Hamiltonian, with the Hermitian component giving rise to oscillations, and the anti-Hermitian component leading to the invisible decay of neutrinos. We consider the possibility that the oscillation and decay matrix may not commute; in fact, in matter, they will invariably become non-commuting. This would lead to a mismatch between the effective mass eigenstates and the decay eigenstates. Employing a resummation of the Zassenhaus expansion, we develop a formalism for calculating the neutrino oscillation probabilities in the two-flavor scenario. This technique can easily be extended to three flavors.

𝐶𝑃 violation in charm meson decays is expected to be small within the Standard Model (SM) framework, and an observation of a large 𝐶𝑃 asymmetry could indicate new physics. We report measurement of branching fractions and direct 𝐶𝑃 asymmetries 𝐴 𝐶𝑃 in 𝐷 0 → 𝜋 + 𝜋 − 𝜂, 𝐾 + 𝐾 − 𝜂, 𝜙𝜂 and 𝐷 0 → 𝐾 0 𝑆 𝐾 0 𝑆 𝜋 + 𝜋 − decays. For the latter the T-odd asymmetry 𝑎 𝑇𝐶𝑃 sensitive to 𝐶𝑃 violation in the decay, is also measured. This report also covers the search for CP violation in 𝐷 → 𝐾ℎ𝜋𝜋 0 ( ℎ = 𝜋, 𝐾 ) decays. The results are based on the full data collected with the Belle detector at the KEKB asymmetric-energy 𝑒 + 𝑒 − collider.

In this talk we discuss the results of a full-simulation study exploring CP violation in Higgs production through ZZ fusion. The study is performed for CLIC running at a centre-of-mass energy of 1.4TeV, assuming that the Higgs boson is realized as a mixture of scalar and pseudoscalar states. By measuring the electron and positron in the final state, the CP-violating mixing angle (cid:9) CP can be probed at the HZZ production vertex
