New results concerning the production of K+, K-, (o), K0s and A particles in the reaction Ar + KC1 at 1.76 AGeV measured by the HADES Collaboration are presented. Transverse momentum distributions have been measured in several rapidity slices for all the particles mentioned above in a ...

Measurement of K0(e3) form-factors The semileptonic decay of the neutral K meson, KL -> pi e nu (Ke3), was used to study the strangeness-changing weak interaction of hadrons. A sample of 5.6 million reconstructed events recorded by the NA48 experiment was used to measure ... A Lai,...
Abstract We describe a calculation of the spectrum of strange and nonstrange hadrons that simultaneously correlates the dressed-quark-core masses of meson and baryon ground- and excited-states within a single framework. The foundation for this analysis is a symmetry-preserving Dyson–Schwinger equation...
The K0/π- ratio and strangeness supression in v p and {Mathematical expression} charged current interactionsNeutral kaon to negative pion production ratios from vp and {Mathematical expression} charged current interactions in BEBC are presented and compared with LUND fragmentation model predictions. ...
In this poster, the recent measurement of the near-side jet yield and the out-of-jet yield of K0 S and Ξ is shown as a function of the multiplicity of charged particles produced in pp collisions at √ B = 13 TeV. The ratio between the Ξ and the K0 S yields is also shown, to...

The strangeness photoproduction process has been intensively studied based on the high-quality data of the charged kaon channel, γ + p + K+ + A(Σ0). On the other hand, there was no reliable data for the neutral kaon channel γ+n + K0+A(Σ0). The theoretical investigations suffer ...
strangenessWe present a study ofK0and螞0production in$p\\bar{p}$minimum-bias interactions at$\\sqrt{s} = 1800$and 630 GeV. Data is collected by the CDF detector at the Tevatron collider. Comparative analyses of various inclusive distributions and correlations for the minimum-bias sample as ...
We report a measurement of the CP violation parameter η+− from the time-dependent asymmetry between the decay rates of initially tagged K0 and K0. The results are based on the complete data sample collected by the CPLEAR collaboration. With Δm=(530.1±1.4)×107ℏs−1 and τS=(...
