Abstract
We look at K/ π ratio as an indicator for strangeness enhancement and compare cosmic data with the collider data.We use CORSIKA to generate data on Extensive Air Showers (EAS) and compare the K/ π ratio with accelerator results.Experimentally observed cosmic K/ π values are also compared with results from hadronic and symmetric and asymmetric nucleus-nucleus collisions.Since Cosmic Rays (CRs) consist mostly of protons and the atmosphere is rich mainly in nitrogen and oxygen we expect more proton-nucleus type collisions to occur and such a scenario agrees well with the experimental values.
