“…If the exponent matrix has two dimensions, a generalized Euler formula gives a straightforward answer. Be Λ represented as a superposition of Pauli matrices Λ = Λ µ σ µ (11) with σ 0 = unit matrix, σ k = Pauli matrices, Λ µ complex. (Summation over multiple indices: Greek 0 to 3, Roman 1 to 3).…”

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.

“…Particle and antiparticle are distinguished only by the flavor quantum number, exhibiting the phenomenon of flavor oscillations in their time evolution [1,2] (see also [3][4][5][6][7][8][9][10]). In the following we will focus on K-mesons, but our conclusions can be easily generalized to the other flavored meson systems, as discussed at the end of the paper.…”

Are Collapse Models Testable via Flavor Oscillations?

et al. 2013

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.

“…Hence, the total efficiency to observe a final state K 0 L (K 0 S ) differs from that expected for either K 0 orK 0 . This effect is related to the coherent regeneration of neutral kaons [22]. However, the detectorsimulation program GEANT4 does not take into account this effect.…”

Using 2.92 fb −1 of electron-positron annihilation data collected at √ s = 3.773 GeV with the BESIII detector, we obtain the first measurements of the absolute branching fractionL e + νe differential decay rate distribution, the product of the hadronic form factor and the magnitude of the CKM matrix element, f K + (0)|Vcs|, is determined 3 to be 0.728 ± 0.006(stat.) ± 0.011(sys.). Using |Vcs| from the SM constrained fit with the measured f K + (0)|Vcs|, f K + (0) = 0.748 ± 0.007(stat.) ± 0.012(sys.) is obtained, and utilizing the unquenched LQCD calculation for f K + (0), |Vcs| = 0.975 ± 0.008(stat.) ± 0.015(sys.) ± 0.025(LQCD).
