The use of jets as a probe in p+A and e+A collisions allows access to the interaction of the hard-scattered partons with the nuclear environment and is sensitive to a wide range of scales. Recent advances in the use of jet substructure offer the potential for an even more finely-grained understanding of this interaction. Measurements of jets and jet substructure in these systems will provide...
The RAA of pions in small system collisions like p/d/He+Au at high pT show suppression in central collisions and enhancement in peripheral collisions. Although the suppression can be understood by probable formation of Quark Gluon Plasma (QGP) in central collision, there is no known physics mechanism to understand the observed enhancement.
As direct photons are transparent to the QGP and...

Recent results from the proton-proton collision data taken by the ATLAS experiment on exotic resonances will be presented. A search for $J/\psi\ p$ resonances in $\Lambda_b \to J/\psi\ p K$ decays with large $pK$ invariant masses will be reported. Studies of $Z_c$ states in $B$-meson decays with the Run 2 data at 13 TeV will also be discussed. Searches for exotic resonances in 4 muon final...
