During the past year, part of my research focused on the quark structure of the nucleon and pion. It is amazing that a simple statistical model is able to reproduce reasonably well the excess of d-bar quarks over u-bar in the proton. We (Mary Alberg and I) have applied this model to pions where it also is able to reproduce the valence quark distribution. We intend to refine the model. Another aspect of my research (with Greg Carter) was on the change of the time component of the axial vector coupling constant in nuclei. This coupling increases by about 100% in heavy nuclei, but theory is only able to account for part of this increase; we have thought of a new mechanism which we are investigating. During the past decade, the progress made in understanding the early universe is nothing short of phenomenal. Several of us ( W-Y. P. Hwang, M.B. Johnson, L.S. Kisslinger, Ho-M. Choi, and I) are trying to understand the electroweak phase transition and the creation of magnetic fields now observed in the polarization of the CMBR.
