Lorentz non-invariance — •Jacob Noordmans — KVI, Groningen, The Netherlands

To our present understanding nature is invariant under rotations and boosts to very high precision. This Lorentz invariance is one of the cornerstones of our most important physical theories: general relativity and the standard model of particle physics. Both are tested to high accuracy. The possibility exists that the theory unifying these two theories breaks Lorentz invariance at some (high) energy scale. At energies presently reachable with experiments, small signals of this Lorentz breaking might still be detectable. We discuss an effective field theory approach to calculate observables so on can put bounds on Lorentz symmetry breaking by measuring them. In this the focus is on the weak interaction.
