Ξ− and Ω distributions in hadron–nucleus interactions

Strange baryons have long been known to exhibit a leading particle effect. A recent comparison of Ξ− production in π− , n, and Σ− interactions with nuclei show this effect clearly. These data are supplemented by earlier measurements of Ξ− and Ω production by a Ξ− beam. We calculate the Ξ− and Ω xF distributions and nuclear dependence in hA interactions using the intrinsic model. PACS: 12.38.Lg;...

Plasmon Resonances for Biospecific Interactions Sensing

An implementation of plasmon resonances in nanocomposite thin films for biosensors is discussed. The effect is studied in the system of modified Au inclusions inside the Teflon matrix. The optical response of the nanocomposite thin film with inhomogeneous distribution of embedded coated Au spherical nanoparticles across the film thickness is analyzed. The absorption profiles are calculated in a...

Mean-motion resonances in satellite–disc interactions

Mean-motion resonances between a Keplerian disc and an orbiting companion are analysed within a Hamiltonian formulation using complex canonical Poincaré variables, which are ideally suited to the description of eccentricity and inclination dynamics. Irreversibility is introduced by allowing for dissipation within the disc. A method is given for determining the rates of change of eccentricity an...

Meson-baryon interactions and baryon resonances

Meson-baryon interactions are the fundamental building blocks to study the structures of baryon resonances and meson properties in few-body nuclear systems. We review the recent progress in the investigation of the meson-baryon interaction in the strangeness S “ ́1 sector and the structure of the Λp1405q resonance. In particular, we present an attempt to construct a realistic KN-πΣ interaction i...
