The Stueckelberg Field
Henri Ruegg, Marti Ruiz-Altaba
In 1938, Stueckelberg introduced a scalar field which makes an Abelian gauge theory massive but preserves gauge invariance. The Stueckelberg mechanism is the introduction of new fi…
The Road to Stueckelberg's Covariant Perturbation Theory as Illustrated by Successive Treatments of Compton Scattering
J. Lacki, H. Ruegg, V. Telegdi
We review the history of the road to a manifestly covariant perturbative calculus within quantum electrodynamics from the early semi-classical results of the mid-twenties to the co…
Lattice Poincare as a quantum deformed algebra
Cesar Gomez, Henri Ruegg, Philippe Zaugg
We propose a definition of a Poincaré algebra for a two dimensional space--time with one discretized dimension. This algebra has the structure of a Hopf algebra. We use the link be…
Bicrossproduct structure of -Poincare group and non-commutative geometry
Shahn Majid, Henri Ruegg
We show that the -deformed Poincaré quantum algebra proposed for elementary particle physics has the structure of a Hopf agebra bicrossproduct $U(so(1,3))\cobicross T$. The alge…
Classical and Quantum Mechanics of Free \k Relativistic Systems
J. Lukierski, H. Ruegg, W. J. Zakrzewski
We consider the Hamiltonian and Lagrangian formalism describing free \k-relativistic particles with their four-momenta constrained to the \k-deformed mass shell. We study the modif…
Twisted Classical Poincaré Algebras
Jerzy Lukierski, Henri Ruegg, Valerij N. Tolstoy +1
We consider the twisting of Hopf structure for classical enveloping algebra , where is the inhomogenous rotations algebra, with explicite formulae given for $…
