Multiskyrmions and baryonic bags

Strange Multiskyrmions ∗

Using a recently proposed approximation for multiskyrmion fields based on rational maps we study the masses and baryonic radii of some strange multibaryons within the bound state soliton model. We find the tetralambda binding to be stronger than previously expected. In addition, the model predicts the existence of a “heptalambda” which is stable against strong decays. PACS: 12.39Dc, 21.80+a

Eyelid bags

Eyelid bags are considered a sign of ageing, but they often appear prematurely due to the variety of causes that favor them. This brief report describes the case of a patient who was referred to us for the correction of a second degree bilateral palpebral ptosis that the patient had suffered from for several years and that in recent months had worsened to the point of interfering with vision an...

Bounded Stacks, Bags and Queues

We prove that a bounded stack can be specified in process algebra with just the operators alternative and sequential composition and iteration. The bounded bag cannot be specified with these operators, but can be specified if we add the parallel composition operator without communication (free merge). The bounded queue cannot even be specified in this signature; we need a form of variable bindi...

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...
