TL;DR: In this paper, a search for T-violating transverse muon polarization (P(T)) in the K+pi(0)mu(+)nu decay was performed using kaon decays at rest.
Abstract: A search for T-violating transverse muon polarization (P(T)) in the K+-->pi(0)mu(+)nu decay was performed using kaon decays at rest. A new improved value P(T)=-0.0017+/-0.0023(stat)+/-0.0011(syst) was obtained giving an upper limit |P(T)|<0.0050. The T-violation parameter was determined to be Imxi=-0.0053+/-0.0071(stat)+/-0.0036(syst) giving an upper limit |Imxi|<0.016.

TL;DR: In this article, the feasibility of quantum-correlation measurements in nuclear physics experiments was investigated, and the results confirmed the effectiveness of the setup for these studies, despite limitations of a small data sample recorded during the feasibility studies.
Abstract: We investigated the feasibility of quantum-correlation measurements in nuclear physics experiments. In the first approach, we measured spin correlations of singlet-spin (1S0) proton pairs, which were generated in 1H(d,2He) and 12C(d,2He) nuclear charge-exchange reactions. The experiment was optimized for a clean preparation of the 2He singlet state and offered a 2π detection geometry for both protons in the exit channel. Our results confirm the effectiveness of the setup for these studies, despite limitations of a small data sample recorded during the feasibility studies.

TL;DR: In this article, a comparison of the observed spectra with a Monte Carlo simulation determined the $K{e4}^{00}$ form factor, which is compatible with the K^+ \to \pi^0 \pi+ \pi-e^0 e^+ ǫ+
u$ data, as estimated from the $\Delta I=1/2$ rule.
Abstract: The $K^+ \to \pi^0 \pi^0 e^+
u$ ($K_{e4}^{00}$) decay has been measured with stopped positive kaons for a data sample of 216 events. A comparison of the observed spectra with a Monte Carlo simulation determined the $K_{e4}^{00}$ form factor. The results are compatible with the $K^+ \to \pi^+ \pi^- e^+
u$ data, as estimated from the $\Delta I=1/2$ rule. We also established that the $K_{e4}^{00}$ channel can be used to determine the $\pi$-$\pi$ scattering lengths.

TL;DR: In this article, the feasibility of nuclear physics experiments designed to overcome the loopholes of observer-dependent reality and satisfying the counterfactuality condition was investigated, and the results of these measurements are used to test the Bell and Wigner-Belinfante inequalities against the predictions of quantum mechanics.
