“…Thus, the huge difference in two decay widths is special to K-mesons and this is one reason that they are attractive to various foundational tests, such as e.g. tests for nonlocality [46][47][48][49][50][51] or the very working of a quantum eraser [34,[52][53][54].…”

Are Collapse Models Testable via Flavor Oscillations?

Collapse models predict the spontaneous collapse of the wave function, in order to avoid the emergence of macroscopic superpositions. In their mass-dependent formulation, they claim that the collapse of any system's wave function depends on its mass. Neutral K, D, B mesons are oscillating systems that are given by Nature as superposition of different mass eigenstates. Thus they are unique and interesting systems to look at, for analyzing the experimental implications of such models, so far in agreement with all known experiments. In this paper we derive-for the single mesons and bipartite entangled mesons-the effect of the mass-proportional CSL collapse model on the dynamics on neutral mesons, including the relativistic effects. We compare the theoretical prediction with experimental data from different accelerator facilities.

“…Some examples are: (i) the quantum-mechanical result for the correlation among two distant particles in an entangled state, rather than a weaker correlation limited by the assumption of Local Realism [110][111][112], (ii) the perturbation expansion of the Schrödinger equation [113,114] leading to the two dimensional spinor representation with the exponential decay law, (iii) the unitarity relations [115], (iv) the complementarity of CP parity and strangeness [116][117][118], (v) that the K 0 and the K 0 from φ decay are exact CPT conjugates [84], (vi) the conservation of the purity of states of isolated particles, manifested by the long time coherence of the kaon matter wave [65,66]. On the last subject, data from the CPLEAR Collaboration in combination with earlier data from the CERN-HEIDELBERG Collaboration achieve a sensitivity of ≈ 10 −21 GeV.…”

“…(234) tells us that we have zero knowledge of whether the particle came originally from the noth pole, or from the south pole. For more detailed considerations, see for instance [116][117][118]. From the left, the 200 MeV/c p beam delivered by LEAR enters the magnet along its axis, and through a thin scintillator (Beam monitor) reaches a pressurized hydrogen gas target (T) where antiprotons stop and annihilate.…”

During the recent years experiments with neutral kaons have yielded remarkably sensitive results which are pertinent to such fundamental phenomena as CPT invariance (protecting causality), time-reversal invariance violation, coherence of wave functions, and entanglement of kaons in pair states. We describe the phenomenological developments and the theoretical conclusions drawn from the experimental material. An outlook to future experimentation is indicated.

“…[13] the authors investigated physical situations for which the expressions of V 0 (y), P(y) and φ(y) can be calculated analytically. This included interference patterns of various types of double slit experiments (y is linked to position), but also oscillations due to particle mixing (y is linked to time), e.g.…”

Quantum mechanics can also be tested in high energy physics; in particular, the neutral kaon system is very well suited. We show that these massive particles can be considered as qubits -kaonic qubits-in the very same way as spin-1 2 particles or polarized photons. But they also have other important properties, namely they are instable particles and they violate the CP symmetry (C. . . charge conjugation, P . . . parity). We consider a Bell inequality and, surprisingly, the premises of local realistic theories require strict CP conservation, in contradiction to experiment. Furthermore we investigate Bohr's complementary relation in order to describe the physics of the time evolution of kaons. Finally, we discuss quantum marking and eraser experiments with kaons, which prove in a new way the very concept of a quantum eraser.
