In the Standard Model (SM), the Higgs boson couples to fermions with a Yukawa-type interaction and a strength proportional to the fermion mass. The associated production of a Higgs boson with a top-quark pair (ttH) is therefore the best direct probe of the top-Higgs Yukawa coupling, a vital element to verify the SM nature of the Higgs boson.

Differential Measurement of the Associated Production of a Single Top Quark and a Z Boson at the CMS Experiment
DPG Frühjahrstagung Dortmund 2021 (Fachverband Teilchenphysik), DPG2021, DESYDortmund (online), DESY, Germany (online), 15 Mar 2021 - 19 Mar 20212021-03-152021-03-19
The top quark is the heaviest particle of the standard model (SM) and can be produced through strong interactions in top quark-antiquark pairs, or polarised as a single top quark (or antiquark) via the electroweak interaction. The associated production of a single top quark and a Z boson (pp → tZq) includes the tZ coupling as well as the coupling of three vector bosons (WWZ) and is therefore a unique process to study the couplings of heavy particles in the SM.

Precision tests of the Standard Model are of utmost importance in particle physics, not only in order to test existing theories but also to probe the realm of new physics. The top quark is of particular interest in this context, as its heavy mass can link it to production- and decay-modes of new processes at higher energy scales. [...]

Searching for Dark Matter in top quark production with the CMS experiment

Astronomical observations provide strong evidence that a large proportion of the matter in the universe is "Dark Matter" (DM) not described in the Standard Model (SM) of particle physics. Furthermore, many cosmological models suggest Dark Matter should couple to the SM on the 100 GeV scale, and hence may be produced at the LHC, appearing as missing transverse momentum. [...]

The Large Hadron Collider (LHC) will undergo a major High Luminosity upgrade with the goal of delivering a peak instantaneous luminosity of about 5−7.5 × 1034cm−2s−1 by 2027. In order for the CMS experiment to cope with the higher radiation levels and data rates, the current CMS Silicon Outer Tracker will be replaced. [...]
