 Reducing parasitic resonances in particle accelerators components by broadband Higher-Order-Mode couplers / Arpaia, P. (Naples U.) ; Berrig, Olav E. (CERN) ; De Vito, Luca (Sannio U.) ; Gilardi, Antonio (Naples U. ; CERN) In particle accelerator components, parasitic resonances must be reduced because they heat up the equipment and cause beam instabilities.

 Design, Construction and Commissioning of the Upgrade Radiation Damage Monitoring System of the CMS Hadron Forward Calorimeters / Onel, Yasar (Iowa U.) /CMS Collaboration The CMS Hadron Forward Calorimeters cover pseudorapidities between 3.0 and 5.0 being exposed to the highest radiation levels in the CMS detector system. The calorimeter consists of quartz fibers as active media inserted into the steel absorber structure. [...] CMS-CR-2018-413.- Geneva : CERN, 2018 - 5 p.

 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.
