Anomaly detection search for new resonances decaying into a Higgs boson and a generic new particle $X$ in hadronic final states using $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector
A search is presented for a heavy resonance $Y$ decaying into a Standard Model Higgs boson $H$ and a new particle $X$ in a fully hadronic final state. [...]

Ferromagnetic phase transitions in $SU(N)$ / Polychronakos, Alexios P. (City Coll., N.Y. ; CUNY, Graduate School - U. Ctr.) ; Sfetsos, Konstantinos (Athens U. ; CERN)
We study the thermodynamics of a non-abelian ferromagnet consisting of "atoms" each carrying a fundamental representation of $SU(N)$, coupled with long-range two-body quadratic interactions. [...]

Recent measurements of W and Z (+jets) at ATLAS and CMS / Amram, Oz (CERN)
Vector boson measurements at the LHC are an ideal laboratory to study detailed properties of the QCD and electroweak sectors of the Standard Model. [...]

[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..
