Random walk on Sierpinski-type multifractals
A method is established which allows the calculation of the walk dimension
for Sierpinski-type multifractals. The multifractal scaling behaviour of the
average time needed to cover a distance in the mentionned multifractals is
shown. For the average-time-multifractal we calculate the Renyi dimensions and
allpy the f(alpha)-formalism.Comment: 9 pages, Postscrip
Twenty Years of Diffraction at the Tevatron
Results on diffractive particle interactions from the Fermilab Tevatron
pbar-p collider are placed in perspective through a QCD inspired
phenomenological approach, which exploits scaling and factorization properties
observed in data. The results discussed are those obtained by the CDF
Collaboration from a comprehensive set of single, double, and multigap soft and
hard diffraction processes studied during the twenty year period since 1985,
when the CDF diffractive program was proposed and the first Blois Workshop was
held.Comment: 6 pages, Presented at EDS-2005, XIth International Conference on
