abstract
Axion-like particles (ALPs) are ubiquitous in models of new physics explaining some of the most pressing puzzles of the Standard Model. However, until relatively recently, little attention has been paid to its interplay with flavour. In this work, we study in detail the phenomenology of ALPs that exclusively interact with up-type quarks at the tree-level, which arise in some well-motivated ultra-violet completions such as QCD-like dark sectors or Froggatt-Nielsen type models of flavour. Our study is performed in the low-energy effective theory to highlight the key features of these scenarios in a model independent way. We derive all the existing constraints on these models and demonstrate how upcoming experiments at fixed-target facilities and the LHC can probe a vast region of the parameter space, which is currently not excluded by cosmological and astrophysical bounds. We also emphasize how a future measurement of the currently unavailable meson decay $D \to \pi + \rm{invisible}$ could complement these upcoming searches and help to probe a large unexplored region of their parameter space.

Constraints on axion-like particles using lattice QCD calculations of the rate for $J/\psi \to \gamma a$
First lattice QCD calculation of the J/psi to gamma plus axion-like-particle form factor, with under 2% uncertainty, used to update ALP constraints.

Long-lived sterile neutrinos from axionlike particles at the Super Tau-Charm Facility
STCF can reach |V_eN|^2 values one to two orders of magnitude below current bounds for heavy neutral leptons via displaced-vertex searches from ALP decays in D-meson production.

Could an axion-like particle be hidden in $\eta_c\to\gamma\gamma$?
The authors propose that an axion-like particle with mass about 2.98 GeV and width about 31 MeV may explain the discrepancy in eta_c to gamma gamma measurements and show it is not yet excluded.
