Applying electroweak factorization for the quantum field theory of the Standard Model at its highest energies (when it is in its unbroken phase) speeds up calculations considerably for EW vector-boson fusion (VBF) processes which constitute the bulk of the cross section at parton collisions beyond a TeV. Furthermore, this formalism is very important for the conceptual understanding of the EW interactions at these energies and paves the way for resumming large logarithms necessary for precision predictions.

We review linear e+e− colliders with a special focus on high centre-of-mass energies and beam polarisation, take a fresh look at the various accelerator technologies available or under development and, for the first time, discuss how a facility first equipped with a technology mature today could be upgraded with technologies of tomorrow to reach much higher energies and/or luminosities. In addition, we will discuss alternative collider modes, as well as opportunities for beyond-collider experiments and R&D facilities as part of a linear collider facility (LCF). [...]

The CMS experiment will be upgrading its detectors in lieu of higher luminosities and collision rates during the High-Luminosity era of the LHC (HL-LHC). One key upgrade of the CMS detector will be its end-cap calorimeters, which will be fitted with the new High Granularity Calorimeter (HGCAL). [...]

The CMS experiment plans to upgrade its calorimeter endcap for the high luminosity phase of the LHC with the High Granularity Calorimeter (HGCAL). The Tilemodule is one of the basic elements in the hadronic calorimeter part of the HGCAL. [...]

At the high-luminosity LHC the CMS Tracker will be faced with unprecedented instantaneous luminosity. To cope with this harsh environment, the existing tracker will be replaced with a completely new system that will operate at -35 degree C. [...]

High Luminosity era of the LHC is fast approaching and the upgrades of the detector systems are now in various stages of production. The CMS experiment will receive a High Granularity Calorimeter (HGCAL) to replace the existing endcaps. [...]

The production of three top quarks (3-top) has been identified as a promising signal for probing new physics beyond the Standard Model (BSM). Various BSM models propose a hypothetical Z’ boson that preferentially couples to top quarks, which could manifest as an enhanced 3-top signal, a scenario yet unexplored by the CMS experiment. [...]

The standard model is an effective theory but a low-energy approximation to a more complete theory. Supersymmetry (SUSY) extends the Standard Model but is expected to be broken and mediated to the visible sector via mechanisms like gravity or gauge mediation. [...]

We present an ongoing analysis of differential cross section measurements for top-pair (tt) production in proton-proton collisions at a center-of-mass energy of 13 TeV, using events containing two oppositely charged leptons. The data were recorded with the CMS detector at the CERN LHC. [...]
