We present some preliminary measurements of Λ[sup 0] polarization, in the final state pp → p{Λ[sup 0]K[sup +]) created at 800 GeV/c, as a function of P[sub T], x[sub F], and the diffractive mass of the object {Λ[sup 0]K[sup +]}.

    We intend to use experimental data to apply the helicity formalism to calculate the spin dependent amplitudes for the following Λc+ three body decays: Λc+ → Σ+π-π+ and Λc+ → Σ+π-π+. Because these decays involve baryons with non-zero spin, the...

  • Today’s view on strangeness. Ellis, John // European Physical Journal A -- Hadrons & Nuclei;May2005 Supplement 2, Vol. 24, p3 

    There are several different experimental indications, such as the pion-nucleonSterm and polarized deep-inelastic scattering, which suggest that the nucleon wave function contains a hiddencomponent. This is expected in chiral soliton models, which also predicted the existence of new exotic...

    Differential cross-section and single polarization observables in the process γp→ K + Λ are investigated within a constituent-quark model and a dynamical coupled-channel formalism. The effects of two new nucleon resonances and of the K *(892)- and K1(1270)-exchanges are briefly...

    Effects of T-odd asymmetry in ternary-nuclear-fission reactions induced by polarized cold neutrons are considered within quantum theory. It is shown that the asymmetry coefficient can be expressed in terms of experimental angular distributions of third particles in reactions induced by...
