Photon-tagged measurements of jet quenching with ATLAS / Perepelitsa, Dennis (University of Colorado Boulder)
Events containing a high transverse momentum ($p_\mathrm{T}$) prompt photon offer a useful tool to study the dynamics of the hot, dense medium produced in heavy ion collisions. [...]

Prospects for $H\rightarrow c\bar c$ using Charm Tagging with the ATLAS Experiment at the HL-LHC
The expected sensitivity of a search for decays of the Higgs boson into charm quarks is estimated for the ATLAS detector at the HL-LHC, by extrapolating the results obtained using a dataset with an integrated luminosity of $36.1\ \text{fb}^{-1}$ at $\sqrt{s}=13\ \text{TeV}$. [...]
