In particular, we numerically measure the probability distribution Q(T) of the translocation time T, and the distribution P(s,t) of the translocation coordinate s at various times t. When scaled with the mean translocation time <T>, Q(T) becomes independent of polymer length, and decays exponentially for large T. The probability P(s,t) is well described by a Gaussian at short times, with a variance that grows sub-diffusively as t^α with α~0.8. For times exceeding <T>, P(s,t) of the polymers that have not yet finished their translocation has a non-trivial stable shape.5 pages, 4 figuresStatistical Mechanicstext
