Is CP Violation Observable in Long Baseline Neutrino Oscillation Experiments ?

We have studied the direct measurements of CP violation in the neutrino oscillations: the difference of the transition probabilities between CP -conjugate channels in the long baseline accelerator experiments. In those experiments, the CP violating effect is not suppressed if the highest neutrino mass scale is taken to be 1 ∼ 10eV, which is appropriate for the cosmological hot dark matter. The ...

Electroweak Baryogenesis with Cosmic Strings? Electroweak Baryogenesis with Cosmic Strings?

I report on a critical analysis of the scenario of electroweak baryoge-nesis mediated by nonsuperconducting cosmic strings. This mechanism relies upon electroweak symmetry restoration in a region around cosmic strings, where sphalerons would be unsuppressed. I discuss the various problems this scenario has to face, presenting a careful computation of the sphaleron rates inside the strings, of t...

Baryogenesis with Superheavy Squarks

We consider a setup where R-parity is violated in the framework of split supersymmetry. The out-of-equilibrium decays of heavy squarks successfully lead to the generation of a baryon asymmetry. We restrict the R-parity violating couplings to the baryon number violating subset to keep the neutralino sufficiently stable to provide the dark matter. The observed baryon asymmetry can be generated fo...

Baryogenesis with Scalar Bilinears

We show that if a baryon asymmetry of the universe is generated through the outof-equilibrium decays of heavy scalar bilinears coupling to two fermions of the minimal standard model, it is necessarily an asymmetry conserving (B−L) which cannot survive past the electroweak phase transition because of sphalerons. We then show that a surviving (B − L) asymmetry may be generated if the heavy scalar...

A Partially Observable Markovian Maintenance Process with Continuous Cost Functions

In this paper a two-state Markovian maintenance process where the true state is unknown will be considered. The operating cost per period is a continuous random variable which depends on the state of the process. If investigation cost is incurred at the beginning of any period, the system wit I be returned to the "in-control" state instantaneously. This problem is solved using the average crite...
