Black Holes, Extra Dimensions and the LHC

Eram Rizvi (Queen Mary)


The standard model of particle physics is a very successful theory able to describe a wide variety of phenomena and experimental data. Yet tensions and shortcomings of the theory exist. One such problem is the complete lack of any mention of the fundamental interactions of gravity. This is due to the shocking feebleness of this force in comparison with all other quantum interactions. This is equivalent to stating that the Planck scale, the energy regime where quantum and gravitational interactions are expected to be similar, is enormously large. Many extensions to the standard model are possible and from the viewpoint of a naive experimentalist I will discuss models in which the Planck scale is reduced to the Electroweak scale by introducing additional structure to space-time, namely extra spatial dimensions. I will consider existing tests of gravity and implications for the LHC experiments.
