Single top and rare top quark production (including FCNC searches) at CMS and ATLAS / May, Samuel (Boston U.) /ATLAS and CMS Collaborations
Measurements of single top and rare top quark production may be sensitive to theories of physics beyond the standard model (SM), especially those in which the energy scale of new physics is beyond the energies directly accessible at the Large Hadron Collider. Such models may be observable through signatures like forbidden SM interactions or deviations of the top quark's couplings from the SM predictions. [...]

YSF Search for production of charginos and neutralinos in hadronic final states at CMS / Kanuganti, Ankush Reddy (Baylor U.) /CMS Collaboration
The results from a search for chargino-neutralino or chargino pair production via electroweak interactions are summarized. The results are based on a sample of $\sqrt{s}$ = 13 TeV proton-proton collisions from the LHC, recorded with the CMS detector and corresponding to an integrated luminosity of 137\,fb$^{-1}$. [...]

Recent results from the ATLAS and CMS Collaborations will be summarized on various measurements related to soft QCD processes. Those include double parton scattering in different final state channels, diffraction and rapidity gap distributions, lepton pair production via photon fusion, strange hadron production as a function of mass and transverse momentum in heavy ion collisions, and particle correlations.

SM Higgs inclusive and differential XS measurements at CMS and ATLAS / Viliani, Lorenzo (INFN, Florence) /ATLAS and CMS Collaborations
Ten years after the announcement of the Higgs boson discovery by the ATLAS and CMS collaborations at the CERN LHC, the paradigm has definitely changed from searching for a new resonance to performing precision measurements of its properties. In fact, thanks to the large amount of proton-proton collision data collected by the ATLAS and CMS experiments in the LHC Run 2, we can now perform precise differential measurements of the Higgs boson production cross section in several decay channels and for all the main production mechanisms.

Recent CMS heavy flavor physics results / Simone, Federica Maria (INFN, Bari ; Bari U.) /CMS Collaboration
In this paper, recent results in the B-physics field achieved using proton-proton collision data at $\sqrt{s}=8$ TeV and $13$ TeV collected by CMS are presented. They include the angular analysis of the decay $\mathrm{B^{+}}\to \mathrm{K}^{*+} \mu^{+} \mu^{-}$ with Run 1 data, new measurements of D and B mesons production cross sections and CP violation studies using ${B}_s^{0}$ decays with Run 2 data.

Performance monitoring of the GE1/1 Triple-GEM detectors for the CMS Muon System / Milella, Gabriele (DESY) ; Simone, Federica Maria (INFN, Bari ; Bari U.) /CMS Collaboration
The muon system of the CMS experiment has been instrumented with two wheels of triple-GEM detectors in order to ensure redundancy in the pseudo-rapidity region 1.55-2.18 so keeping the trigger rate at an acceptable level while not compromising the CMS physics potential in Run 3 of the LHC.The station, named GE1/1, provides two additional muon hit measurements which will improve the muon tracking and triggering performance in combination with the existing CSC detectors.As the commissioning phase of the detector is ongoing, prompt assessment of the muon detection performance is crucial for adjusting the operating parameters of the detector and its electronics. This contribution will present a set of analysis tools developed for the detector performance monitoring based on tools common to all the CMS muon subdetectors. [...]

BSM H searches and rare H decay searches at CMS and ATLAS / Cooperstein, Stephane B (UC, San Diego) /ATLAS and CMS Collaborations
Searches for rare Higgs boson decays and extensions of the Higgs sector beyond the standard model are key to probing the dynamics of electroweak symmetry breaking. With the large LHC Run-2 dataset, considerable progress has been made in probing the largely unexplored Higgs boson interactions with the lighter fermions, as well as in searching for signs of new physics in the Higgs sector with mass scales ranging from 100 MeV to several TeV.
