Using Anti de-sitter/Quantum Chromodynamics (AdS/QCD), a new technique proposed as being complementary to traditional Lattice QCD, the complete set of angular observables in the rare B→K∗μ+μ− decay using light-front holographic B→K∗ transition form factors were predicted. Light front holographic AdS/QCD is a relatively new technique that maps 4-dimensional non-perturbative QCD field theory to a dual gravitational theory in a higher dimensional curved space. Whereas fields under the quantum field theory are strongly interacting, the ones using gravitational theory are weakly interacting. This means that we can use perturbative theory in this 5-dimensional dual gravity theory, and then map it back to QCD field theory to predict non-perturbative QCD qualities. This AdS/QCD technique is being applied in B→K∗μ+μ−, and more specifically in this thesis, to compute the angular observables of this decay. Angular observables are particularly sensitive to New Physics beyond the Standard Model (SM). The anomalies previously found using Lattice QCD for the P′5 and a FB angular observables were confirmed using AdS/QCD.
