SuperWIMPs at the LHC
Abstract: We will review the status of SuperWIMP Dark Matter and then discuss recent bounds and prospects at the LHC especially in the case of stop NLSP. We will then discuss an intriguing idea of connecting SuperWIMP gravitino DM with baryogenesis at the weak scale through R-parity breaking.

Aspects of Locally Conformal Spinnetworks
Abstract: Spinnetworks are a 3d geometry employed as the kinematical states of Loop Quantum Gravity (LQG) and Spin Foam (SF) models, the covariant counterpart to the Hamiltonian formulation of LQG. In this talk we explore a particular representation (all 3 Casimirs proportional) of the cotangent bundle of the double cover of the conformal group T*SU(2,2) that sits inside T*SL(2, C). We find that the generator of dilatations changes the extrinsic curvature of the triangulation, something we interpret as curving the edges of the tetrahedra of the triangulation. This has previously been suggested to account for the cosmological constant in the SF-models, which is currently described by the quantum group T*SL_q(2, C). We also discuss a possible extension of the construction to locally conformal spinnetworks that take into account all possible values of the 3 Casimirs of the conformal group. This talk will be preceded by a relatively lengthy introduction to both LQG and SF-models to highlight the main ideas behind the quantization of geometry and the particular constructions.
