Dynamical sectors of a relativistic two particle model / Dominici, Daniele (INFN, Florence ; Florence U.) ; Gomis, Joaquim (CERN ; ICC, Barcelona U. ; Barcelona U., ECM) ; Kamimura, Kiyoshi (Toho U.) ; Longhi, Giorgio (INFN, Florence ; Florence U.)
We reconsider a model of two relativistic particles interacting via a multiplicative potential, as an example of a simple dynamical system with sectors, or branches, with different dynamics and degrees of freedom.The presence or absence of sectors depends on the values of rest masses. Some aspects of the canonical quantization are described. [...]

Space-time Vector Supersymmetry and Massive Spinning Particle / Casalbuoni, Roberto. (Florence U. ; INFN, Florence) ; Gomis, Joaquim (CERN ; Barcelona U., ECM ; ICC, Barcelona U.) ; Kamimura, Kiyoshi (Toho U.) ; Longhi, Giorgio (Florence U. ; INFN, Florence)
We construct the action of a relativistic spinning particle from a non-linear realization of a space-time odd vector extension of the Poincar\'e group. For particular values of the parameters appearing in the lagrangian the model has a gauge world-line supersymmetry.{As a consequence of this local symmetry there are BPS solutions in the model preserving 1/5 of the supersymmetries.} A supersymmetric invariant quantization produces two decoupled 4d Dirac equations..

Anisotropic harmonic oscillator, non-commutative Landau problem and exotic Newton-Hooke symmetry / Alvarez, Pedro D. (Chile U., Santiago) ; Gomis, Joaquim (Barcelona U., ECM ; CERN) ; Kamimura, Kiyoshi (Toho U.) ; Plyushchay, Mikhail S. (Chile U., Santiago)
We investigate the planar anisotropic harmonic oscillator with explicit rotational symmetry as a particle model with non-commutative coordinates. It includes the exotic Newton-Hooke particle and the non-commutative Landau problem as special, isotropic and maximally anisotropic, cases. [...]

Gauge and BRST Generators for Space-Time Non-commutative U(1) Theory / Gomis, Joaquim (CERN ; Barcelona U., ECM ; Barcelona, IFAE) ; Kamimura, Kiyoshi (Toho U.) ; Mateos, Toni (Barcelona U., ECM ; Barcelona, IFAE)

Hamiltonian Formalism for Space-time Non-commutative Theories / Gomis, Joaquim (CERN ; Barcelona, IFAE) ; Kamimura, Kiyoshi (Toho U.) ; Llosa, Josep (Barcelona, IFAE)
Space-time non-commutative theories are non-local in time. We develop the Hamiltonian formalism for non-local field theories in d space-time dimensions by considering auxiliary d+1 dimensional field theories which are local with respect to the evolution time. [...]
