"For their leading role in the first demonstration of mixing in the BO - B-O system. The unexpectedly large value of the mixing parameter provided indirect evidence for a large top quark mass and has greatly enhanced the possibility for studying CP violation in B meson decays. This capability has encouraged a worldwide effort to determine whether the small CP violation in K decay is a reflection of a fundamental parameter characterizing transitions of quarks among the three generations."Background:
Dr. Schroder studied physics at the Universities of Berlin and Freiburg/Br. where he obtained his diploma degree in 1969 and Ph.D. degree in 1973. He was a scientific assistant at the University of Freiburg/Br. From 1970 to 1976, a post-doctoral researcher at the MPI fur Kernphysik in Heidelberg from 1974 to 1977, and has been a scientific employee at DESY from 1977 to the present. Since 1989 he has taught at the University of Dortmund and since 1993 at the University of Rostock. In 1996 he became a Professor at the University of Dortmund.
Dr. Schroder studied light nuclei as a Ph.D. student and investigated hypernuclei as a postdoctoral researcher at CERN from 1974 to 1977. At DESY he worked with the DASP2 experiment which looked at the resonances in e+e- interactions for the first time. Since 1978 he has held leading positions with the ARGUS experiment and has been its spokesman since 1990. He is particularly interested in heavy quark decays with the observation of the Bo-B-o mixing as the most important result along with the first reconstruction of exclusive semileptonic b-c and b-u decays. He is now a member of the HERA-B experiment which will study CP violation in B decays at HERA.
