Thermal Stress Tensor Correlators near Lightcone and Holography / Esper, Chantelle (Hamilton Math. Inst., Dublin) ; Huang, Kuo-Wei (Hamilton Math. Inst., Dublin) ; Karlsson, Robin (CERN) ; Parnachev, Andrei (Hamilton Math. Inst., Dublin) ; Valach, Samuel (Hamilton Math. Inst., Dublin)
We consider thermal stress-tensor two-point functions in holographic theories in the near-lightcone regime and analyse them using the operator product expansion (OPE). [...]

Composing arbitrarily many $SU(N)$ fundamentals / Polychronakos, Alexios P. (City Coll., N.Y. ; CUNY, Graduate School - U. Ctr.) ; Sfetsos, Konstantinos (Athens U. ; CERN)
We compute the multiplicity of the irreducible representations in the decomposition of the tensor product of an arbitrary number $n$ of fundamental representations of $SU(N)$, and we identify a duality in the representation content of this decomposition. [...]

Indirect searches at CMS / Smith, Nicholas
In these proceedings, we present several new measurements of Standard Model (SM) processes, in the Higgs sector and beyond, that push the precision frontier forward at CMS. [...]

Combination and summary of ATLAS dark matter searches interpreted in a 2HDM with a pseudo-scalar mediator using 139 fb$^{-1}$ of $\sqrt{s} = 13$ TeV $pp$ collision data / ATLAS Collaboration
Results from a wide range of searches targeting different experimental signatures with and without missing transverse momentum ($E_{\mathrm{T}}^{\mathrm{miss}}$) are used to constrain a Two-Higgs-Doublet Model (2HDM) with an additional pseudo-scalar mediating the interaction between ordinary and dark matter (2HDM+$a$).
