...theory.

The error on 305#305 given by the measurement of Ref. [2] is twice as small as the one quoted in Refs. [9] and [10] because, in those references, only the CPT-violating effect of that parameter is taken into consideration. Another advantage of the test of Ref. [2] is that one can be sure that no constraint derived from quantum coherence was assumed anywhere in the analysis of the events.

...GeV.

This is not yet comparable to the result obtained in neutron interferometry, 10323#323 GeV, [6], but it would be the best result relevant to kaon physics.

...theory.

Because, when particles disappear beyond the horizon of a black-hole, information about their quantum numbers disappears too.

...[#refEllis##1#].

Let 374#374 be the kaon mass and 375#375 the Planck mass. Ref [16] claims there are diagrams leading to rates 376#376 of the order of 377#377, i.e. 2 10378#378 GeV. The ratio of the measured value of 379#379 to 2 10380#380 GeV is a measurement of the coefficient in that diagram. According to this paper, a measurement at Da381#381ne can detect the alleged effect even if that coefficient is much smaller than 1. See Ref [17].
