Search for long-lived particles produced in $pp$ collisions at $\sqrt{s}=13$ TeV that decay into displaced hadronic jets in the ATLAS muon spectrometer
A search for the decay of neutral, weakly interacting, long-lived particles using data collected by the ATLAS detector at the LHC is presented. [...]

CMS emittance scans for 2017 luminosity calibration / Tsrunchev, Peter (CERN) /CMS Collaboration
Emittance scans are short van der Meer type scans performed at the beginning and at the end of LHC fills. The beams are scanned against each other in X and Y planes in 9 displacement steps and are used for LHC diagnostics and since 2017 for CMS luminosity calibration cross check. [...]

Forward energy flow and jet production in pp and pA collisions at the LHC with CMS / Van De Klundert, Merijn H F (DESY) /CMS Collaboration
A measurement of inclusive differential cross sections for very forward jet production is presented as a function of jet energy in proton-lead collisions. These collisions were recorded with the CASTOR calorimeter of the CMS experiment at the LHC, which measures in the pseudorapidity range $-6.6<\eta<-5.2$. [...]

Van der Meer calibration of the CMS luminosity detectors in 2017 / Lujan, Paul Joseph (INFN, Padua) /CMS Collaboration
Precision measurement of luminosity delivered by the LHC to the CMS experiment is a vital component of many physics analyses and important for optimal machine performance. In Run 2, the luminosity at CMS is measured by three online luminometers, the Pixel Luminosity Telescope (PLT), Fast Beam Conditions Monitor (BCM1F), and the hadronic forward calorimeter (HF), which provide high-precision real-time luminosity measurements. [...]

The Matrix Element Method used in the search for the associated production of the Higgs boson with top quarks and decaying into tau leptons / Zabi, Alexandre (Ecole Polytechnique) /CMS Collaboration
Latest results of CMS searches for a Higgs boson produced in association with top quarks in final states with tau leptons are reported. This contribution will specifically focus on technical aspects related to the Matrix Element Method implementation and on its impact on the sensitivity of the analysis. [...]

Level-1 track finding with an all-FPGA system at CMS for the HL-LHC / James, Thomas Owen (Imperial Coll., London) /CMS Collaboration
The CMS experiment at the LHC is designed to study a wide range of high energy physics phenomena. It employs a large all-silicon tracker within a 3.8 T magnetic solenoid, which in particular allows precise measurements of transverse momentum ($p_\mathrm{T}$) and vertex position.\\ This tracking detector will be upgraded to coincide with the installation of the High-Luminosity LHC, which will provide a luminosity up to about $7.5 \times 10^{34}\,\mathrm{cm^{-2}\,s^{-1}}$ to CMS, or 200 collisions per 25~ns bunch crossing.

Top modelling and tuning in CMS / Zenaiev, Oleksandr (DESY) /CMS Collaboration
State-of-the-art theoretical predictions accurate to next-to-leading order QCD interfaced with Pythia8, Herwig, and Sherpa event generators are tested by comparing the unfolded $t\bar{t}$ differential data collected with the CMS detector at 8 and 13 TeV. These predictions are also compared with the underlying event activity distributions in $t\bar{t}$ events using CMS proton-proton data collected at a center of mass energy of 13 TeV. [...]

Top quark and electroweak physics / Skinnari, Louise (Cornell U.)
Measurements of top quark and electroweak processes are central in confronting the Standard Model in all corners of phase space and probing signs of physics beyond this successful, yet incomplete, model. These proceedings summarize the status of physics involving the top quark and electroweak sectors, ranging from precision measurements of production cross sections and Standard Model parameters, such as the weak mixing angle, to studies of rare processes, such as electroweak vector-boson scattering and four top quark production.

Finite-volume matrix elements of two-body states / Baroni, Alessandro (South Carolina U.) ; Briceño, Raúl A. (Jefferson Lab ; Old Dominion U.) ; Hansen, Maxwell T. (CERN) ; Ortega-Gama, Felipe G. (Coll. William and Mary)
In this talk, we present a framework for studying structural information of resonances and bound states coupling to two-hadron scattering states. [...]
