    FCNC and non-standard soft-breaking terms in weak-scale Supersymmetry

    Full text link
    We study the inclusion of non-standard soft-breaking terms in the minimal SUSY extension of the SM, considering it as a model of weak-scale SUSY. These terms modify the sfermion mass matrices, which can induce new sources of flavour violation. Bounds on the new soft parameters can be estimated from current data. The results are then applied to evaluate FCNC top decay t -> c + hi (hi= h,H,A). Implications of complex soft parameters for CP violation are also addressed.Comment: Revised version (8 pages), title changed and references corrected.

    Gauge-Higgs unification with brane kinetic terms

    By identifying the Higgs field as an internal component of a higher dimensional gauge field it is possible to solve the little hierarchy problem. The construction of a realistic model that incorporates such a gauge-Higgs unification is an important problem that demands attention. In fact, several attempts in this direction have already been put forward. In this letter we single out one such attempt, a 6D SU(3) extended electroweak theory, where it is possible to obtain a Higgs mass prediction in accord with global fits. One shortcoming of the model is its prediction for the Weinberg angle, it is too large. We slightly modify the model by including brane kinetic terms in a way motivated by the orbifold action on the 6D fields. We show that in this way it is possible to obtain the correct Weinberg angle while keeping the desired results in the Higgs sector.Comment: 11 pages, 2 figures. References added.

    In ES implementations, process modelling is a critical and often overlooked activity. This paper proposes a framework for process modelling of ES. The four steps method involves: Current Situation Analysis, Business Process Improvements and Requirements, Gap Analysis, and To-be process to develop. Outputs of the methodology are an interdependent set of organizational and system proposed changes, and feedback loops to the ES vendors and to the strategy of the firm. In-depth case studies and extensive literature review provides methodological support. For practitioners, this study provides useful insights into one of the reasons by which companies could be frustrated with ES implementation.E-business, ERP
