DELPHI (Detector with Lepton, Photon and Hadron Identification) is one of the four large detectors presently operating at the Large Electron Positron Collider (LEP) at CERN (European Center for Nuclear Research). The DELPHI experiment is performed by a collaboration of 52 laboratories from 20 countries, including 31 laboratories from 11 countries of the European Union and two international organizations (CERN in Geneva an JINR in Dubna).The Russian group (IHEP) in Protvino, consisting of 40 people, has been in DELPHI from the very beginning of the collaboration. Its contribution to the construction of DELPHI detector is around 5 %. At present, the IHEP group, in collaboration with several groups from countries of the European Union, is actively participating in the physics analysis of the data collected by DELPHI in 1990 - 1993, with more than 2 millions of Zdegrees decays recorded, in the upgrade of the DELPHI detector, in the preparation for the new physics to be done at LEP 200 and in the running of the DELPHI in 1994 run. Among the joint studies in physics with the highest priority in the coming year are: beauty physics - study of the production and the decay properties of B-particles, search for the Higgs boson, electroweak physics - precise measurement of the Zdegrees parameters, and the study of non-perturbative QCD soft processes. The main hardware project with strong participation by the IHEP group is DELPHI's new very forward electromagnetic calorimeter (the STIC). The IHEP group will continue to keep its key position in a number of DELPHI's off-line and on-line software projects. It will also remain responsible for running the Forward Scintillator Hodoscope (HOF), together with the Dubna group the Hadron Calorimeter (HCAL), and in collaboration with several other DELPHI groups the STIC.
