We shall follow the growth of probability theory and applications from the 1650s onwards, in parallel with the development of statistical inference. Bayesian, Neyman-Pearson hypothesis testing and Fisherian likelihood methods will all be covered, with an emphasis on relating theory to a wide range of applications. Practical sessions will use SciPy and feature closed-form solutions, iterative and Monte Carlo simulation methods.

High Energy Physics

We review recent breakthroughs in understanding some general features of the Renormalization Group and of Quantum Field Theory. We discuss some applications of these new results and their deep connection to the entanglement of the Quantum Field Theory vacuum.

We derive the collective theory of singlet fields of large-N Sp(N) spin models and display its unconventional features. Using the known relationship between O(N) collective fields and higher spin fields of Vasiliev theory in AdS space, we argue that the unique features of the Sp(N) collective theory suggest an interpretation in terms of a higher spin theory in de Sitter space, as proposed by Anninos, Hartman and Strominger. This is reminiscent of the way the Liouville mode is naturally interpreted as time in supercritical worldsheet string theory.
Supermassive black holes in non-spherical galactic nuclei and enhanced rates of star capture events

Astrophysics

We consider the stellar-dynamical processes which lead to the capture or tidal disruption of stars by a supermassive black hole, review the standard theory of two-body relaxation and loss-cone repopulation in spherical galactic nuclei, and extend it to the axisymmetric and triaxial nuclear star clusters. In the absense of symmetry which conserves angular momentum, the orbits of stars experience regular or chaotic changes of angular momentum even in the smooth potential of star cluster, which creates a substantial population of "centrophilic" orbits. We discuss the loss cone draining rates, i.e. rates of capture of stars from these orbits. Next we consider the relaxation phenomena in non-spherical nuclei, focusing on the differences between spherical, axisymmetric and triaxial cases. It turns out that the rates of repopulation of the loss cone are moderately higher in non-spherical systems, but in the triaxial case an additional, often substantial, increase of capture rates comes from draining of the centrophilic orbit population.
