Strange particle production in high-energy electron Proton collision / Zukhaimira binti Zolkapli

The strangeness total cross sections for ep neutral current deep inelastic scattering (DIS) have been measured using HERA-II data at a center-of-mass energy of s  318 GeV with the ZEUS detector at HERA. The 2003 & 2007 running period data were used with an integrated luminosity of 4.6 pb-1 and...
