Limits on CP invariance in general relativity.

Physical Review D, 1988
The test of the equivalence principle pointed out by Longo and by Krauss and Tremaine can be easily extended to comparing the infall velocities of matter and antimatter. The very close coincidence in arrival times for neutrinos and antineutrinos places strong constraints on the coupling of gravitational interactions to matter and antimatter.

First test of CP invariance in the decay of positronium.

Physical Review Letters, 1991
The 3\ensuremath{\gamma} decay of spin-aligned triplet positronium (Ps) is used for a test of CP invariance (charge conjugation and parity). This is the first use of the Ps atom to investigate the CP symmetry. The angular correlation (S^\ensuremath{\cdot}k${\mathrm{^}}_{1}$)(S^\ensuremath{\cdot}k${\mathrm{^}}_{1}$\ifmmode\times\else\texttimes\fi{}k ...

Rephasing invariants andCPviolation

Physical Review D, 1986
We discuss all possible rephasing invariants of the Kobayashi-Maskawa matrix. We find that all CP-violation phenomena of the KM matrix are expressed by linear or quadratic functions of one special class of nine invariants and the imaginary parts of these invariants are the same with respect to the KM angles and phase i.e. ${C}_{1}$${C}_{2}$${C}_{3}$${S}

CP invariance: A point of view

Pramana, 1983
That the longlived componentL ofK 0 has bothcp=+1 andcp=−1 modes of decay is often cited as evidence of violation ofcp invariance. The careful ones find the compelling evidence to be the non-dilution of the regeneration interference pattern when the incidentK 0 beam is mixed even substantially with

Comment on Jarlskog’s conditions forCPinvariance

Physical Review D, 1989
In a previous work we derived for the quark mass matrices in the standard model with any number of families, n, a set of basis-independent conditions, which are necessary and sufficient for CP invariance. Very recently Jarlskog claimed to have reduced the number of these conditions for n>3 to (1/2(n-1)(n-2) = the number of Kobayashi-Maskawa-type phases.

Invariant Formulation of CP Violation

1999
CP violation can be described with expressions invariant under redefinitions of the weak fermion basis. This formulation is explicitly known for the Standard Model extensions with one sequential or vector-like quark and for its left-right version. The invariant formulation is very useful in model building and is specially suitable to the syudy of ...
