Shed Light

World data on Λ – p scattering in pion-induced redactions are quite scare. In 2014 the HADES Collaboration performed an experiment campaign with pionnucleon reactions π¯ + A (A = C,W) at 1.7 GeV/c. Hereby, the exclusive channel π¯ + p → K0 + Λ (Λ + p → Λ + p) may provide information on Λ proton scattering and moreover shed light on the short range interaction using dedicated simulations for comparison. The on-going analysis of the exclusive channel with especial emphasis on the event selection is outlined.

Critical behaviors in quenched random-spin systems with N-spin component are studied in the limit M → 0 of the non-random MN-component models by means of the renormalization group theory. As the static critical phenomena the stability of the fixed points is investigated and the critical exponents η[~ O(ε3); ε ≡ 4 – d], γ, α, and crossover index [Formula: see text] and the equation of state [~ O(ε)] are obtained. Within the approximation up to the order ε2, even the random-spin systems with N = 2 or 3 are unstable in the three dimensions and the pure systems are stable there.

We report numerical investigation of the short range interaction influence on the two-dimensional quantum scattering of two dipoles. The model simulates two ultracold polar molecules collisions in two spatial dimensions. The used algorithm allows us to quantitatively analyse the scattering of two polarized dipoles with account for strongly anisotropic nature of dipolar interaction. The strong dependence of the scattering total cross section on the short range interaction radius was discovered for threshold collision energies. We also discuss differences of calculated scattering cross section dependencies for different polarisation axis tilt angles.
