The heavy flavour physics program at SLD relies upon the vertex finding capabilities of the pixel vertex detector (VXD3). In turn, the tracking and vertexing resolution depends upon a precise knowledge of the location and orientation of the 96 elements of the VXD3 in 3D space. The matrix inversion technique of singular value decomposition (SVD) is employed to unfold the detector geometry corrections from the track data in the VXD3, adapting the algorithm to perform an optimal c2 minimization. The resolution obtained is compared with the starting point, based on an optical survey, and is shown to achieve the design performance.

MSSM is believed to be one of the best candidates for the physics beyond the Standard Model. In this talk I shall review the particle contents of MSSM, and their possible direct signals at different present and future colliders.

In the last few years, a new scenario for the cosmic origin of dark matter has emerged. Rather than resulting from collisions of particles in the hot primordial soup, dark matter would be produced by the conversion of virtual particles to real particles caused by the rapid expansion of the universe during the inflationary epoch. Implications of the new source of dark matter for present dark matter searches will be discussed.

Hadro-production of charmonium has received a lot of attention in recent years. The data collected by fixed target and Tevatron experiments are not described by available theoretical models. In addition, the understanding of different mechanisms of nuclear suppression in charmonium production is essential to explain the anomalous J/y suppression observed by NA50 collaboration. HERA-B is a fixed target experiment in DESY which provides an excellent base to study the charmonium production and related nuclear effects. In the first part of the seminar, the compilation of the experimental data and the comparison with the models will be discussed. In the second part the potential of HERA-B for the measurements of charmonium production as well as results of data taking in year 2000 will be presented.
