Saturation of current algebra equations with higher baryonic resonances

Search for Baryonic Resonances

A search for narrow baryonic resonances produced in deep inelastic scattering and decaying to K s p (K s p̄) or Ξ−π− (Ξπ and their antiparticles) is carried out with the H1 detector at HERA. No signal is observed for a new baryonic state. Upper limits on σ(ep → eΘX) × BR(Θ → Kp) and on the ratio of the production rates of hypothetical baryonic states relative to the Ξ(1530) baryonic state are ob...

Kleene Algebra with Equations

We identify sufficient conditions for the construction of free language models for systems of Kleene algebra with additional equations. The construction applies to a broad class of extensions of KA and provides a uniform approach to deductive completeness.

Reduction of Differential Equations by Lie Algebra of Symmetries

The paper is devoted to an application of Lie group theory to differential equations. The basic infinitesimal method for calculating symmetry group is presented, and used to determine general symmetry group of some differential equations. We include a number of important applications including integration of ordinary differential equations and finding some solutions of partial differential equa...

Baryonic resonances dynamically generated from the interaction of vector mesons with stable baryons of the decuplet

Using the hidden gauge approach for the interaction of vector mesons we evaluate the interaction of vector mesons of the octet of the ρ with the baryons of the ∆ decuplet. Scattering amplitudes are calculated, developing poles for some quantum numbers which we associate to baryonic resonances. Many of these states can be associated to known resonances, while others represent predictions for new...
