Book Description
About three decades after the first experiments on deep inelastic lepton hadron scattering began to investigate the structure of hadrons, the history of this fruitful field of particle physics continues in the broad spectrum of research performed at the electron and positron proton collider HERA at DESY, where the multipurpose detectors ZEUS and H1 access ep scattering at a center of mass energy of 300 GeV and explore as yet uncharted kinematic realms of deep inelastic scattering. After the first years of data taking at HERA, each of the experiments has collected a total of roughly 40 pb 1 of e+p data, yielding sensitivity to deep inelastic e+p interactions at high four momentum transfers, Q2, where typi cal cross sections drop into the subpicobarn regime. This kinematic domain is characterized by electroweak unification, manifesting itself most markedly in the neutral and charged current cross sections, which approach an equal order of magnitude as Q2 rises above the square of the W and Z masses. Consequently, HERA allows, for the first time, studies of both types of pro cesses simultaneously with the same initial state conditions and in the same detector, and thus we can investigate the interplay of electroweak and strong forces governing the respective cross sections.

Book Description
The proceedings of this workshop gather the latest experimental results from HERA and capture new trends in HERA phenomenology. Although the presentations are by experts, they are suitable for both theoreticians and experimentalists. H1 members also cover ZEUS results and vice versa. This volume serves to point out existing discrepancies between experimental data and theoretical predictions and to identify projects to take on in the future.

Book Description
"This thesis presents a first study of various aspects of $K sp0$ and $ Lambda$ production in neutral current deep inelastic scattering of 27.5 GeV positrons and 820 GeV protons. The data were accumulated with the ZEUS detector at HERA in the 1994 run period. The average multiplicities for the neutral strange particle production as functions of pseudorapidity $ eta$ and transverse momentum $p sb{t}$ have been determined in the kinematic range 10 $GeV sp20.04.$ The particle and energy flow with respect to the struck quark direction, as well as the dependence of the average production rate as function of the four-momentum transfer $Q sp2$ and the hadronic centre of mass energy W of the ep scattering process have been studied. The K$ sp0$ and $ Lambda$ multiplicities in the kinematic range 10 $GeV sp20.04$ are compared with the results from data from the 1993 run period with 26.7 GeV electrons and 820 GeV protons. The production mechanisms of $K sp0$ in events with and without large rapidity gaps with respect to the proton direction are compared in order to probe differences in diffractive and non-diffractive scattering processes." --
