We investigate the implications of R-Parity violation (RPV) for quark flavour violation both by constraining the sneutrino masses to be positive and by studying the processes b → sγ and K − K̄ mixing. In the latter there are two major contributions, one from “direct” one loop diagrams involving RPV couplings, and one from the “indirect” contributions generated by the renormalisation group. We co...

Safe data abstractions are widely used for verification purposes. Positive verification results can be transferred from the abstract to the concrete system. When a property is violated in the abstract system, one still has to check whether a concrete violation scenario exists. However, even when the violation scenario is not reproducible in the concrete system (a false negative), it may still c...

Until now the focus within the direct search for supersymmetry has mainly been on flavour diagonal observables. Recently lepton flavour violating signals at future electron positron colliders have been studied. There is now an opportunity to analyse the relations between collider observables and lowenergy observables in the hadronic sector. In a first work in this direction, we study flavour vi...

I review several topics involving CP violation with heavy hadrons. In particular, I discuss (i) Hyperons: CP violation in the decay Λ → pπ, (ii) Charm: indirect CP violation in the D system, both within and beyond the SM, and (iii) Beauty: indirect CP violation in the neutral B-meson system beyond the SM.

We show that for a metastable system there exists a theoretical possibility of a violation of the Clausius inequality without a violation of the second law. Possibilities of experimental detection of this hypothetical violation are pointed out. The question which will be considered here is the possibility of a violation of the Clausius inequality ∮ δQ

We review theoretical and experimental results on CP violation summarizing the discussions in the working group on CP violation at the UK phenomenology workshop 2000 in Durham. ‡ To Appear in Journal of Physics G; Contribution of Working Group 4 to the UK Phenomenology Workshop on Heavy Flavour and CP Violation, Durham, 17 22 September 2000 CP Violation, UK Phenomenology Workshop 2000 2

Particle identification, in particular the identification of charged pions and kaons, plays an important role for studies CP violation B Factory experiments. For BELLE detector at KEK B-Factory Japan, a threshold aerogel Cherenkov counter (ACC) has been used to separate kaons momentum range between 1.0 GeV/c 3.5 GeV/c. This paper gives brief description ACC design, construction, monitoring syst...

We study CP violation in a multi-Higgs doublet model based on a S3 × Z3 horizontal symmetry where CKM phase is not the principal source of CP violation. 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 Higgs boson mixings. Both mechanisms can explain the observed CP violation in the neutral...

In recent years there has been a great deal of interest in R-parity violating supersymmetric models. We explain the motivation for studying these models and explore the various phenomenological consequences of R-parity violation. In particular, we argue that if we are to explore all channels for the discovery of supersymmetry then these models must be investigated. It has become essential for t...
