Quantized Coulomb Branches, Monopole Bubbling and Wall-Crossing Phenomena in 3d $\mathcal{N}=4$ Theories / Assel, Benjamin (CERN) ; Cremonesi, Stefano (Durham U., Dept. of Math.) ; Renwick, Matthew (Durham U., Dept. of Math.)
To study the quantized Coulomb branch of 3d $\mathcal{N}=4$ unitary SQCD theories, we propose a new method to compute correlators of monopole and Casimir operators that are inserted in the $\mathbb{R}\times\mathbb{R}^2_\epsilon$ Omega background. [...]

Emergent Strings from Infinite Distance Limits / Lee, Seung-Joo (CERN) ; Lerche, Wolfgang (CERN) ; Weigand, Timo (CERN ; U. Mainz, PRISMA)
As a refinement of the Swampland Distance Conjecture, we propose that a quantum gravitational theory in an infinite distance limit of its moduli space either decompactifies, or reduces to an asymptotically tensionless, weakly coupled string theory. [...]

Bose-Einstein correlations of charged hadrons in proton-proton collisions at $\sqrt{s} = $ 13 TeV
Bose-Einstein correlations of charged hadrons are measured over a broad multiplicity range, from a few particles up to about 250 reconstructed charged hadrons in proton-proton collisions at $\sqrt{s} = $ 13 TeV. [...]

Measurement of the $t\bar{t}$ production cross-section and lepton differential distributions in $e\mu$ dilepton events from $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
The inclusive top quark pair ($t\bar{t}$) production cross-section $\sigma_{t\bar{t}}$ has been measured in proton-proton collisions at $\sqrt{s}=13$ TeV, using $36.1$ fb$^{-1}$ of data collected in 2015-16 by the ATLAS experiment at the LHC. [...]

Mixed higher-order anisotropic flow and nonlinear response coefficients of charged particles in PbPb collisions at ${\sqrt {\smash [b]{s_{_{\mathrm {NN}}}}}} = $ 2.76 and 5.02 TeV
Anisotropies in the initial energy density distribution of the quark-gluon plasma created in high energy heavy ion collisions lead to anisotropies in the azimuthal distributions of the final-state particles known as collective flow. [...]
