[YSF] Lepton flavor violation in the top quark sector / Li, Jingyan (Northeastern U.) /CMS Collaboration
This document describes a search for charged-lepton flavor violation (CLFV) in the production and decay of top quarks using 138 fb$^{-1}$ of data collected by the CMS experiment at a center-of-mass energy of 13 TeV. Events are selected for analysis if they contain an opposite-sign electron-muon pair, a third charged lepton (electron or muon), at least one jet, and at most one jet associated with a bottom quark. [...]

Indirect searches at CMS / Smith, Nicholas (Purdue U.) /CMS Collaboration
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. Results are presented in the context of a framework parameterizing deviations in Higgs boson couplings, as well as in the context of SM Effective Field Theory, where new analyses targeting Higgs, top,and multi-boson processes probe an increasingly diverse set of operators. [...]

DiHiggs searches / Roy, Dennis Mario (Kansas State U.) /ATLAS, CMS and Higgs collaborations
Recent results on analyses of non-resonant di-Higgs production by the ATLAS and CMS experiments are presented. These analyses feature never before studied di-Higgs production modes and final states, new interpretations in the Higgs or standard model effective field theories, and updated results from the combination of different analyses..

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. [...]
