Non-metricity signatures on the Higgs boson signal strengths at the LHC

Victor Ilisie

英文摘要:

In this work we study the high-energy Higgs boson phenomenology associated to the non-metricity scale $Λ_Q$ at the LHC. Non-metricity is present in more generic non-Riemannian geometries describing gravity beyond General Relativity and exhibits nice features in astronomy and cosmology, and it can be analysed perturbatively. Using effective field theory tools, we calculate the new physics contributions to the one-loop $H\toγγ$ and $gg\to H$ processes and, together with previous bounds from Compton scattering, we obtain relevant constraints and correlations in the model's parameter space. This can help us take a step further, and no longer associate gravitational effects uniquely to astronomical phenomena, and to start analysing these effects by means of high energy experiments. In turn, this could also help us get a better grasp at quantum phenomena associated to gravity.
