Query: Diffusion hitting times and the Bell-shape   Consider a generalized diffusion on R with speed measure m, in the natural
scale. It is known that the conditional hitting times have a unimodal density
function. We show that these hitting densities are bell-shaped if and only if m
has infinitely many points of increase between the starting point and the hit
point. This result can be viewed as a visual corollary to Yamazato's general
factorization for diffusion hitting times.
