Observing Superradiance of Light Vector Particles
Abstract: We will discuss how the process of superradiance, combined with gravitational wave measurements, makes black holes into nature's laboratories to search for new light bosons. We will present analytic results for superradiance of light vector (spin-1) particles, valid in the regime where the vecto... read more

Dark matter from the Fraternal Twin Higgs
Speaker(s): Robert Lasenby
Abstract: Twin Higgs theories attempt to solve the little hierarchy problem - why has the LHC not yet observed new states stabilising the EW scale? - by introducing a SM-neutral twin sector, related to the SM by an approximate Z_2 symmetry. The physical Higgs is then a PNGB mixture from both sectors, and acts... read more

Nuclear Dark Matter - Synthesis and Phenomenology
Speaker(s): Robert Lasenby
Abstract: I will talk about the physics of models in which dark matter consists of composite bound states carrying a large conserved dark “nucleon” number. The properties of sufficiently large dark nuclei may obey simple scaling laws, and this scaling can determine the number distribution of nucl... read more
