2 8 M ay 2 00 4 Integrable quadratic Hamiltonians on so ( 4 ) and so ( 3 , 1 ) Vladimir

In this paper we consider the following family of Poisson brackets {Mi,Mj} = εijk Mk, {Mi, γj} = εijk γk, {γi, γj} = κ εijk Mk. (1.1) Here Mi and γi are components of 3-dimensional vectors M and Γ, εijk is the totally skew-symmetric tensor, κ is a parameter. It is well-known that any linear Poisson bracket is defined by an appropriate Lie algebra. The cases κ = 0, κ > 0 and κ < 0 correspond to ...

The Conformal Group SO(4, 2) and Robertson-Walker spacetimes

The Robertson-Walker spacetimes are conformally flat and so are conformally invariant under the action of the Lie group SO(4, 2), the conformal group of Minkowski spacetime. We find a local coordinate transformation allowing the Robertson-Walker metric to be written in a manifestly conformally flat form for all values of the curvature parameter k continuously and use this to obtain the conforma...

2 00 4 A Not So Little Higgs ?

Most recent models assuming the Higgs Boson is a pseudo-Nambu-Goldstone Boson (pNGb) are motivated by the indication from Standard Model fits that its mass is ≤ 200GeV .Starting from a modified SM. of Forshaw et. al. with a triplet boson added and a heavier Higgs Boson, we consider a pNGb model.This differs in several ways from most little Higgs models: apart from using only one loop, the cutof...
