✦ Synopsis

Searches for exotic strange baryon resonances decaying into K 0 s p,K 0 s p, and Ξπ were performed by the H1 collaboration in deep inelastic scattering (DIS) at HERA. Upper limits are given for the production rates. Deuterons and anti-deuterons were observed by the ZEUS collaboration and their production rates in DIS were compared to those of p(p). Strange neutral hadrons were produced and cross-sections,baryon to meson ratios and relative yields of strange to light mesons were measured by ZEUS. Excited charm non-strange and strange mesons were produced and the fraction of charm quark fragmenting to these mesons was measured by ZEUS.
