  • multi higgs doublet Models Physical parametrization sum rules and unitarity bounds
    Journal of High Energy Physics, 2017
    Co-Authors: Miguel Bento, Howard E Haber, J C Romao, J Silva
    Abstract:

    If the scalar sector of the Standard Model is non-minimal, one might expect multiple generations of the hypercharge-1/2 scalar doublet analogous to the generational structure of the fermions. In this work, we examine the structure of a Higgs sector consisting of N Higgs doublets (where N ≥ 2). It is particularly convenient to work in the so-called charged Higgs basis, in which the neutral Higgs vacuum expectation value resides entirely in the first Higgs doublet, and the charged components of remaining N − 1 Higgs doublets are mass-eigenstate fields. We elucidate the interactions of the gauge bosons with the Physical Higgs scalars and the Goldstone bosons and show that they are determined by an N × 2N matrix. This matrix depends on (N − 1)(2N − 1) real parameters that are associated with the mixing of the neutral Higgs fields in the charged Higgs basis. Among these parameters, N − 1 are unPhysical (and can be removed by rephasing the Physical charged Higgs fields), and the remaining 2(N − 1)2 parameters are Physical. We also demonstrate a particularly simple form for the cubic interaction and some of the quartic interactions of the Goldstone bosons with the Physical Higgs scalars. These results are applied in the derivation of Higgs coupling sum rules and tree-level unitarity bounds that restrict the size of the quartic scalar couplings. In particular, new applications to three Higgs doublet Models with an order-4 CP symmetry and with a $$ {\mathbb{Z}}_3 $$ symmetry, respectively, are presented.

  • a model driven approach to enterprise data migration
    Conference on Advanced Information Systems Engineering, 2015
    Co-Authors: Raghavendra Reddy Yeddula, Prasenji Das, Sreedha Reddy
    Abstract:

    In a typical data migration project, analysts identify the mappings between source and target data Models at a conceptual level using informal textual descriptions. An implementation team translates these mappings into programs that migrate the data. While doing so, the programmers have to understand how the conceptual Models and business rules map to Physical databases. We propose a modeling mechanism where we can specify conceptual Models, Physical Models and mappings between them in a formal manner. We can also specify rules on conceptual Models. From these Models and mappings, we can automatically generate a program to migrate data from source to target. We can also generate a program to migrate data access queries from source to target. The overall approach results in a significant improvement in productivity and also a significant reduction in migration errors.
