Recent experimental progress in meson spectroscopy has revealed numerous resonant states that do not fit the conventional quark model, leading to a plethora of theoretical and phenomenological models being proposed to explain their existence. However, to move beyond phenomenology and achieve a model-independent understanding, one must turn to QCD itself. In this talk, I will review the...
The asymptotic states of QCD are observed to be colour singlets. Among the possible colour singlets one can build there is the experimentally unconfirmed glueball, a bound state of gluons. Lattice simulations of $SU(3)$ Yang-Mills are able to probe several glueball channels and predict that the lightest states is heavy. With dynamical fermions the glueball becomes unstable and can mix with...
The Fermilab measurement of the anomalous magnetic moment of the muon $a_\mu$ at 127ppb is one of the most precise experimental tests of the Standard Model. However, the ultimate interpretation of this result is still unclear due to significant tensions in the theoretical predictions, particularly those of the hadronic vacuum polarisation (HVP) contributions $a_\mu^\text{HVP}$. The two methods...
