Challenges in Hyperon Decays
We give an personal overview of some of the unsolved problems related to
hyperon decays. We cover nonleptonic decays, radiative decays and magnetic
moments. Some of the theoretical issues are also touched upon.Comment: Contribution to Workshop On Low-Energy Pbar Storage Ring (Pbar2000
On Exactly Solvable Potentials
We investigate two methods of obtaining exactly solvable potentials with
analytic forms.Comment: 13 pages, Latex, to appear in Chineses Journal of Physic
Exact Solution of an One Dimensional Deterministic Sandpile Model
Using the transfer matrix method, we give the exact solution of a
deterministic sandpile model for arbitrary , where is the size of a
single toppling. The one- and two-point functions are given in term of the
eigenvalues of an transfer matrix. All the n-point functions can
be found in the same way. Application of this method to a more general class of
models is discussed. We also present a quantitative description of the limit
cycle (attractor) as a multifractal.Comment: need RevTeX; to appear in Physical Review E January 6, (1995
