**SEZIONE DI FIRENZE** Abstract:
Branching random walks (BRW) are mathematical processes that may model the
dynamics of a variety of physical systems. In particular, they turn out to be
relevant for the study of very high-energy scattering processes in particle
physics, such as electron-nucleus scattering: The total cross section of such a
process is indeed related to the statistics of the lead particles generated by a
peculiar BRW, while some characteristic features of diffractive events can be
deduced from to the properties of genealogical trees of a set of extremal
particles. In this seminar, we will focus on a few universal results on BRW,
which we shall explain with the help of a phenomenological picture that we have
developed.(Stephane Munier) |
