At the time of the Big Bang, matter and antimatter were produced in equal amounts. However, seen as though you exist to read this abstract, there must be an underlying asymmetry between the behaviour of matter and anti-matter in the Universe, giving matter preference and allowing large scale structures to have evolved. This seminar covers some of the recent charge asymmetry results from the DØ experiment's B Physics group, searching for new or enhanced amounts of matter/antimatter preference in B meson oscillations. Updated world-averaged values for the semileptonic charge asymmetries will be presented.
