We comment on CP, T and CPT violation in the light of interesting new data from the CPLEAR and KTeV Collaborations on neutral kaon decay asymmetries. Other recent data from the CPLEAR experiment, constraining possible violations of CPT and the ∆S = ∆Q rule, exclude the possibility that the semileptonic-decay asymmetry AT measured by CPLEAR could be solely due to CPT violation, confirming that t...

The most general Two Higgs Doublet Model (2HDM) allows both for the explicit and the spontaneous CP violation in the scalar sector. Here we discuss CP violation in terms of basisindependent quantities and show how using two different sets of known CP-odd weak-basis invariants one can distinguish between CP conservation, explicit CP violation and spontaneous CP violation. The special case of CP ...

Abstract We study CP violation in a multi-Higgs doublet model based on a S3 × Z3 horizontal symmetry. We consider two mechanisms for CP violation in this model: a) CP violation due to complex Yukawa couplings; and b) CP violation due to scalar-pseudoscalar mixings. We find that the predictions for ǫ/ǫ, CP violation in B decays and the electric dipole moments of neutron and electron are differen...

We show that in supersymmetric models with explicit flavor lepton number violation due to soft supersymmetry breaking mass terms there must be flavor lepton number violation in slepton decays. We propose to look for flavor lepton number violation in righthanded selectron and smuon decays. For selectron and smuon lighter than 80 Gev flavor lepton number violation in slepton decays could be disco...

This report presents the speciication and veriication of a consensual decision protocol used in Co 4 , a computer environment dedicated to the building of a distributed knowledge base. This protocol has been speciied in the Iso formal description technique Lotos. The Cadp tools from the Eucalyptus Lotos toolset have been used to verify diierent safety and liveness properties. The veriication wo...

We show that in the presence of external fields for which either Ḃ 6= 0 or ∇ × E 6= 0 it is not possible to derive the classical Maxwell equations from an action with only one gauge field. We suggest that one possible solution is to consider a second physical pseudo-vector gauge field C. The action for this theory is originally motivated by the inclusion of magnetic monopoles. These particles p...

Bottom meson decay is a promising place to look for CP violation outside the neutral kaon system. It will also facilitate a test of the CP violation mechanism of the standard model [1]. One way to achieve this aim would be to measure decay time asymmetries at the asymmetric B factories presently under construction [2]. But violations of the standard model may show up in B physics in other ways ...

The aforementioned celebrated model, though a breakthrough in Stochastic processes and great step toward the construction of Brownian motion, leads to paradox: infinite propagation speed violation 2nd law thermodynamics. We adapt model by assuming diffusion matrix is dependent on concentration particles, rather than constant it was up Einstein, prove finite under assumption qualified decrease f...

The present status of rare decays of mesons and leptons are reviewed in terms of CP violation and lepton avor violation. Neutrinoless double beta decays are also discussed in terms of lepton number violation.
