 Exotics at the LHC / Del Re, Daniele (INFN, Rome ; Rome U.) /ATLAS, CMS and LHCB Collaborations LHC has worked beautifully and provided more than 100 fb$^{-1}$ at 13 TeV. Thanks to this enormous statistics of p-p collisions, LHC experiments have been able to explore several different new physics scenarios. [...] CMS-CR-2018-392.- Geneva : CERN, 2018 - 11 p.

 Top pair production measurements, inclusive and differential / Fernandez Menendez, Javier (Oviedo U.) /ATLAS, CMS and LHCB Collaborations Recent results and state-of-the-art on top-quark pair production cross sections in both inclusive and differential measurements are presented, obtained using data collected with the ATLAS, CMS and LHCb experiments during the LHC Run1 and Run2 periods up to the year 2016 at centre-of-mass energies ranging from 5.02 to 13TeV. Results are confronted against Standard Model (SM) next-to-leading order (NLO) and next-to-next-to-leading order (NNLO) predictions, several Monte Carlo (MC) generators and tunes, and parton density function variations, with a special focus on the latest Run2 results..

 Top quark properties / Van Mulders, Petra Karel Ann (Vrije U., Brussels) /ATLAS and CMS Collaborations The multi-purpose experiments at CERN's Large Hadron Collider have a very rich programme in top quark physics. The large amount of data allows for measuring the top quark properties with an unprecedented precision. [...] CMS-CR-2018-284.- Geneva : CERN, 2018 - 6 p.

 Top quark mass measurement in the $\mathrm{t\bar{t}}$ all-jets final state with the CMS experiment at $\sqrt{s}=13\,\mathrm{TeV}$ / Lange, Johannes /CMS Collaboration The top quark mass is measured using $35.9~\mathrm{fb}^{-1}$ of LHC proton-proton collision data collected with the CMS detector at $\sqrt{s}=13~\mathrm{TeV}$ in 2016. The measurement uses the $\mathrm{t}\overline{\mathrm{t}}$ all-jets final state, which comprises a total of six jets. [...] arXiv:1812.05394; CMS-CR-2018-386.- Geneva : CERN, 2018 - 6 p.

 Evidence for light-by-light scattering and limits on axion-like-particles from ultraperipheral PbPb collisions at 5 TeV / Niedziela, Jeremi (CERN) /CMS Collaboration A measurement of light-by-light scattering, $\gamma\gamma \rightarrow \gamma\gamma$, in ultraperipheral PbPb collisions at a centre-of-mass energy per nucleon pair of $5.02$ TeV is reported. The analysis is conducted using a data sample corresponding to an integrated luminosity of $390~\mu \rm{b}^{-1}$ recorded by the CMS experiment at the LHC.

 Particle Flow reconstruction in the Level-1 trigger at CMS for the HL-LHC / Petrucciani, Giovanni (CERN) /CMS Collaboration With the planned addition of the tracking information in the Level-1 trigger in CMS for the HL-LHC, the algorithms for the Level-1 trigger can be completely reconceptualized. Following the example for offline reconstruction in CMS to use complementary subsystem information and mitigate pileup, we explore the feasibility of using Particle Flow-like and pileup-per-particle identification techniques at the hardware trigger level.
