Flavour mixing and mass matrices via anticommuting properties
Five anticommuting property coordinates can accommodate all the known
fundamental particles in their three generations plus more. We describe the
points of difference between this scheme and the standard model and show how
flavour mixing arises through a set of expectation values carried by a single
Higgs superfield.Comment: 12 pages, LaTe
A Possible Way of Connecting the Grassmann Variables and the Number of Generation
We construct a Left-Right symmetric model in which the number of generation
is related to Grassmann variables. We introduce two sets of complex Grassmann
variables (,), (, ) and
associate each variable with left- and right-handed quark and lepton fields,
respectively. Expanding quark and lepton fields in powers of the Grassmann
variables, we find that there are exactly three generations of quarks and
leptons. Integrating out the Grassmann variables, we obtain phenomenologically
acceptable fermion mass matrices.Comment: 7 pages, Revtex, UM-P-93/40, OZ-93/1
The determination of derivative parameters for a monotonic rational quadratic interpolant
Explicit formulae are developed for determining the derivative parameters of a monotonic interpolation method of Gregory and Delbourgo (1982)
The low energy effective Lagrangian for photon interactions in any dimension
The subject of low energy photon-photon scattering is considered in arbitrary
dimensional space-time and the interaction is widened to include scattering
events involving an arbitrary number of photons. The effective interaction
Lagrangian for these processes in QED has been determined in a manifestly
invariant form. This generalisation resolves the structure of the weak-field
Euler-Heisenberg Lagrangian and indicates that the component invariant
functions have coefficients related, not only to the space-time dimension, but
also to the coefficients of the Bernoulli polynomial.Comment: In the revised version, the results have been expressed in terms of
Bernoulli polynomials instead of generalized zeta functions; they agree for
spinor QED with those of Schubert and Schmidt (obtained differently by path
integral methods)
Piecewise rational quadratic interpolation to monotonic data
An explicit representation of a piecewise rational quadratic function is developed which produces a monotonic interpolant to given monotonic data. The explicit representation means that the piecewise monotonic interpolant is easily constructed and numerical experiments indicate that the method produces visually pleasing curves. Furthermore, the use of the method is justified by an 0(h4) convergence result
