Enhanced production of multi-strange hadrons in proton-proton collisions

Though models can explain the yield enhancement of strange hadrons, yet they are insufficient to explain the behaviour of multi-strange particles. The models may not be able to explain simultaneously the effects of strangeness canonical suppression in low multiplicity events and QGP like effect in high multiplicity pp collisions at LHC energies. To separately study these effects we have analysed both experimental data and simulation models at low energies and our results will be presented in the conference
