Cross sections for pi+, pi-, K+, and K- mesons on complex nuclei
… diffraction cross sections of 3.5 Gev/c 7r and K mesons on beryllium, carbon, aluminum, copper and lead was made at the Zero Gradient Synchrotron at Argonne National Lab. A set of circular scintillation counters measured transmission as a function of angle for each element. Cross sections were …

A search for heavy leptons using a differential Cherenkov counter
… penetration of lead by particles identified as K mesons in the differential Cherenkov counter. The result is presented as the 95% confidence limit that there is no anomalous penetration of lead by K mesons. This limit is compared with an estimate of the number of. heavy leptons expected as a …

A test of the Delta S = Delta Q selection rule in K°e3 decay
… selection rule for the decay [equation] K mesons were produced by a 3 GeV beam on a carbon target in the reaction [equation]. Even t were reconstructed on the basis of the trajectories of the kaon decay products in optical spark chambers located ina magnetic field. The electron from the …

A Kaon Trigger for FOPI : Development and Evaluation of a Trigger System for Strange Particles
… in particular with respect to the strange K mesons, can extend our knowledge about the structure of nuclear matter and the processes during the evolution of neutron stars and black holes. However, kaons are rarely observed, hence the derived physics results suffer from large uncertainties. In …

Fragmentation and nucleon structure in semi-inclusive deep-inelastic scattering at the HERMES experiment
… production of each charge state of π± and K± mesons in deep-inelastic scattering are presented as a function of the kinematic quantities x, Q2, z and Ph⊥. The multiplicities were extracted from data collected by the HERMES experiment at the HERA storage ring using 27.6 GeV electron and …

Exclusive diffractive dissociation of KL mesons at high energies
… we have observed diffractive dissociation of KL mesons with a carbon target into the exclusive final states Ks pi+pi-, K*(890)+-pi+, Ks Ksw and Kstheta , but not Ks ""t"" The diffractive production cross section for these states is not strongly dependent on incident energy varying at most by 30 …
