 Studies of Boosted Topologies and Jet Substructure at the LHC / Haller, Johannes (Hamburg U.) ; Kogler, Roman (Hamburg U.) ; Tackmann, Frank (DESY) The high centre-of mass energy available in run-2 of CERN's Large-Hadron-Collider (LHC) results in an abundant production of heavy particles with high transverse momenta ($p_T$).

 Searching for hidden matter with long-range angular correlations at $e^+e^-$ colliders / Pérez-Ramos, Redamy (IPSA, Paris) ; Sanchis-Lozano, Miguel-Angel (Valencia U., IFIC ; Valencia U.) ; Sarkisyan-Grinbaum, Edward K. (CERN ; Texas U., Arlington) The analysis of azimuthal correlations in multiparticle production can be useful to uncover the existence of new physics beyond the Standard Model, e.g., Hidden Valley, in $e^+e^-$ annihilation at high energies.

 R-Parity Violation Axiogenesis / Co, Raymond T. (Minnesota U., Theor. Phys. Inst.) ; Harigaya, Keisuke (CERN ; Princeton, Inst. Advanced Study) ; Johnson, Zachary ; Pierce, Aaron We show that the rotation of the QCD axion field, aided by $B-L$ violation from supersymmetric $R$-parity violating couplings, can yield the observed baryon abundance.

 Jet substructure measurements in heavy-ion collisions with ALICE / Mulligan, James (Ahmedabad, Phys. Res. Lab ; Indian Inst. Tech., Gandhinagar) Jet substructure, defined by observables constructed from the distribution of constituents within a jet, provides the versatility to tailor observables to specific regions of QCD radiation phase space.
