Géométrie Des Groupes Oscillateurs Et Variétés Lo- Calement Symétriques
The Oscillator Groups,Gλ, are the only solvable, non commutative, simply connected Lie groups to admit a Lorentzian bi-invariant metric. For these groups, we give sufficient conditions for a left-invariant pseudo-Riemannian metric to be complete, we determine the group of isometries, we exhibit a left-invariant affine structure and prove that it is not Lorentzian. As an application, we provide ...
متن کاملHigh ET jets and double scattering
The recently found excess of high ET jets over current QCD predictions is attributed to gluon radiation at double scattering process inside a nucleon. The order of magnitude estimate of the cross section fits experimental findings rather well. The specific features of the process are discussed. Various similar hadronic effects related to the short radiation length are described. It has been rec...
متن کاملQuark Resonances and High Et Jets.
Possible spin-3/2 quark resonances would have a significant effect on high Et jet production through their contribution to the subprocess q + q̄ → g + g. Such enhancements are compared to a, recently reported, anomaly in inclusive jet production at the CDF detector.

متن کاملHolonomic and Semi - Holonomic Geometries
— Holonomic and semi-holonomic geometries modelled on a homogeneous space G/P are introduced as reductions of the holonomic or semi-holonomic frame bundles respectively satisfying a straightforward generalization of the partial differential equation characterizing torsion–free linear connections. Under a suitable regularity assumption on the model space G/P we establish an equivalence of catego...
متن کاملTo the Theory of Semi { Holonomic Jets
To Ivan Koll a r on the occasion of his 60th birthday. The usual jets were introduced by C. Ehresmann as a fundamental tool in Diierential Geometry. They permit to globalize the theory of diierential systems and to give a formulation of the \innnite groups" of E. Cartan; this leads to the theory of Lie pseudogroups; initiated by C. Ehresmann, this theory was studied by many mathematicians (the ...
