 On the chiral anomaly and the Yang-Mills gradient flow / Lüscher, Martin (CERN ; Bern U. ; U. Bern, AEC) There are currently two singularity-free universal expressions for the topological susceptibility in QCD, one based on the Yang-Mills gradient flow and the other on density-chain correlation functions.

 Measurement of $\mathrm{D}$-meson production as a function of charged-particle multiplicity in proton--proton collisions at $\sqrt{s} = 13$ TeV with ALICE at the LHC / Bailung, Yoshini (Indian Inst. Tech., Indore) Heavy quarks (charm and beauty) are produced in hard-scattering processes and the study of their production in proton--proton (pp) collisions is an important test for calculations based on perturbative Quantum Chromodynamics (pQCD).

 Charmonium suppression in ultra-relativistic Proton-Proton collisions at LHC energies: A hint for QGP in small systems / Singh, Captain R. (Indian Inst. Tech., Indore) ; Deb, Suman (Indian Inst. Tech., Indore) ; Sahoo, Raghunath (Indian Inst. Tech., Indore ; CERN) ; Alam, Jan-e (Calcutta, VECC) Proton-proton ($pp$) collision has been considered as a baseline to study the system produced in relativistic heavy-ion (AA) collisions with the basic assumption that no thermal medium is formed in $pp$ collisions.
