This project aims at developing a new class of experimental probes for new Higgs-like spin-0 particles with the ATLAS experiment at LHC, and to interpret the experimental results in complete models that predict primordial Gravitational Waves (GW).
In the Standard Model, the mass of the Higgs boson is greatly destabilised by quantum corrections, and free parameters of the model need to be extremely fine-tuned in order to arrive at the measured Higgs mass.
