| (left) Pseudodata projections for the nuclear suppression factors of the nuclear gluon density as a function of Bjorken-$x$ for photoproduction of three vector mesons in PbPb UPCs. The points are EPS09-projections using the method described in~\cite{Guzey:2013xba}. From Ref. \cite{Citron:2018lsq}. (right) Exclusion limits on ALP-photon coupling ($1/\Lambda_a)$ vs. ALP mass, from light-by-light scattering and other processes. From Ref. \cite{Aad:2020cje}. |
