Abstract
Abstract Despite the enduring resilience of the Standard Model of particle physics, there remain reasons to expect that it is not a “final” theory. In particular, the Standard Model can not explain either dark matter or the observed matter–antimatter asymmetry of the universe. LHCb is a forward acceptance spectrometer at the Large Hadron Collider, dedicated to precision measurements of heavy flavour particles. Because new particles can appear virtually in the decays of heavy flavour particles, and thus alter their properties, such measurements are inherently sensitive to much higher mass scales that direct searches. We present in this article how the presence of new particles can be probed by testing Lepton Universality in the decay of hadrons containing a b-quark.
