چکیده
The problem of coupling between spin and torsion is analysed from a Lyra's manifold background for scalar and vector massive fields using the Duffin-Kemmer-Petiau (DKP) theory. We found the propagation of the torsion is dynamical, and the minimal coupling of DKP field corresponds to a non-minimal coupling in the standard Klein-Gordon-Fock and Proca approaches. The origin of this difference in the couplings is discussed in terms of equivalence by surface terms.

We derive properties of the radial evolution of scalar fields in anti-de Sitter spacetime from quantum mechanics, through a factorisation of the path integral. We describe why we anticipate application of these results to the AdS/CFT correspondence.

We describe generalizations of the manifestly E6(6) covariant formulation of five-dimensional gauged maximal supergravity with regard to the structure of the vector and tensor fields. We indicate how the group-theoretical structures that we discover seem to play a role in gauged supergravities in various space-time dimensions.

A model of gauge mediation with m 3/2 ≃ O(1) eV is considered to motivate 100 TeV colliders. Massive mediators with standard-model and supersymmetry-breaking gauge quantum numbers let low-scale dynamics induce sizable soft masses of the standard-model superpartners. We circumvent potential phenomenological difficulties that such low-scale models tend to cause.

We explore the Higgs sector of the NMSSM in the limit when the Peccei–Quinn symmetry is exact or only slightly broken. In this case the Higgs spectrum has a hierarchical structure which is caused by the stability of the physical vacuum. We find a strong correlation between the parameters of the NMSSM if κ = 0 or κ λ 2. It allows one to distinguish the NMSSM with exact or softly broken PQ-symmet...

Integrable models of 1 + 1 dimensional gravity coupled to scalar and vector fields are briefly reviewed. A new class of integrable models with nonminimal coupling to scalar fields is constructed and discussed.
