Stringent bounds on $HWW$ and $HZZ$ anomalous couplings with quantum tomography at the LHC
Quantum tomography provides the full reconstruction of the density matrix of a state. We use it to study the Higgs boson decay into weak gauge bosons. Anomalous couplings beyond the Standard Model can be constrained by means of observables easily defined in terms of the polarization density matrix....
