CMS measurements of EFT parameters with top quarks
/ Tonon, Nicolas (DESY)
/CMS Collaboration
Measurements carried out or reinterpreted within the framework of effective field theory (EFT) will constitute a key component of the LHC legacy in the quest towards physics beyond the standard model.
Numerous EFT measurements were already published by the CMS Collaboration.
In the top quark sector, four distinct approaches to EFT have been identified, each successfully applied in several analyses.
We review the pros and cons of each approach, while illustrating them with recent analyses in which they were adopted..

Measurements of ${\rm t\bar t+jets}$, ${\rm t\bar t+b\bar b}$ production, and ${\rm t\bar tt\bar t}$ production at CMS
/ Castro, Andrea (INFN, Bologna ; Bologna U.)
/CMS Collaboration
The most recent CMS measurements of the production of ${\rm t\bar t}$ pairs with two additional jets, or two additional b quarks, are presented. These two processes are important for several reasons: they can allow a better modeling of Monte Carlo simulations, because of the different energy scale associated to b-jets and generic jets; they are important backgrounds to other standard model processes; and they might be related to new physics.

Performance of CMS Endcap Precision Timing Sensors
/ Lazarovits, Margaret (Kansas U.)
/CMS Collaboration
The Large Hadron Collider, a particle accelerator in Geneva, Switzerland, will enter its High Luminosity (HL) phase, whose upgrade has already started. This phase will include an increase in particle collisions, achieving instantaneous luminosities of 5 to 7 times the nominal luminosity, $1~\times~10^{34}$~cm$^{-2}$s$^{-1}$. [...]

Review of results on forward physics and diffraction by CMS
/ Baldenegro Barrera, Cristian (Kansas U.)
/CMS Collaboration
Results by the CMS Collaboration on forward physics, diffraction, and physics in the small-$x$ limit of quantum chromodynamics (QCD), are presented. In particular, results on azimuthal angle decorrelations between two jets in events where two outermost jets are separated by a large rapidity interval are discussed. [...]

Characterisation of planar and 3D Silicon pixel sensors for the high luminosity phase of the CMS experiment at LHC
/ Ceccarelli, Rudy (INFN, Florence ; Florence U.) ; Meschini, Marco (INFN, Florence) ; Viliani, Lorenzo (INFN, Florence) ; Dinardo, Mauro (INFN, Milan Bicocca ; Milan Bicocca U.) ; Gennai, Simone (INFN, Milan Bicocca) ; Menasce, Dario (INFN, Milan Bicocca) ; Moroni, Luigi (INFN, Milan Bicocca) ; Zuolo, Davide (INFN, Milan Bicocca ; Milan Bicocca U.) ; Lino Demaria ; Monteil, Ennio (INFN, Turin ; Turin U.) et al.
The High Luminosity upgrade of the CERN LHC collider (HL-LHC) demands for a new, high-radiation tolerant solid-state pixel sensor capable of surviving fluencies up to a few $10^{16}~ \rm{n_{eq}/cm^2}$ at $\sim 3 \, \rm{cm} $ from the interaction point.
To this extent the INFN ATLAS-CMS joint research activity, in collaboration with Fondazione Bruno Kessler (FBK), is aiming at the development of thin n-in-p type pixel sensors for the HL-LHC [...]
