Abstract

This presentation reports recent results from the hadronic final state in DIS at HERA. Forward jet and π0\pi^0 production have been measured by the H1 experiment. The forward jet production cross section shows significant deviation from the predictions based on DGLAP evolution. The forward π0\pi^0 data discriminate between different QCD models and are best described by models which take into account the partonic substructure of virtual photons. Inclusive Ks0Ks0K_s^0K_s^0 production in epep has been studied with the ZEUS detector using an integrated luminosity of 120 pb1^{-1}. Two states are observed at masses of 1537 MeV and 1726 MeV as well as an enhancement around 1300 MeV. The state at 1537 MeV is consistent with the well established f2(1525)f_2^\prime(1525). The state at 1726 MeV may be the glueball candidate f0(1710)f_0(1710).
