As an extension of the standard model, Vector Like Quarks provide a possible solution to various unsolved issues, such as the hierarchy problem. This analysis focuses on the single production of the vector-like top quark T′, in the decay channel T′→ tH (H→ WW), in the final state with two opposite sign leptons. [...]

Deep Inelastic Scattering (DIS) events at HERA are the most precise DIS measurement to date, which constitutes an important tool to study transverse momentum dependent (TMD) parton distribution functions. In this study, we introduce standard DIS Monte Carlo events recreating HERA conditions, and apply their cross section as a constraint for both photon and heavy boson TMDs in the Parton Branching Method..

The Standard Model (SM) Higgs boson is predicted to be CP-even. Measurements from Run 2 data at the LHC have excluded a purely CP-odd state at 3 standard deviations. [...]

As the High Luminosity era of LHC approaches, it is important to finalise production techniques for the components of the upgrades of the collider experiments and CMS is no exception. The CMS endcap calorimeters are getting a high granularity upgrade (HGCAL), which promises to improve energy resolution by reducing background via pileup rejection. [...]

Top quark pair production processes at the LHC are important for precision measurements of observables such as the top quark mass or top quark pair spin correlations and as a background for BSM searches. As such, it is crucial that MC simulation of this process is available for experimental analyses at the highest level of precision possible. [...]

A precision measurement of the top quark pair production cross section at 13.0 TeV is presented. The data were recorded at the CMS experiment and correspond to an integrated luminosity of 59.8 fb−1. [...]

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. [...]

The Compact Muon Solenoid (CMS) has the world's largest silicon tracker, comprising 1856 pixel modules and 15148 strip modules that ensure accurate track reconstruction. In order to maintain high precision one must compensate for significant time variations caused by magnet cycles, temperature variations and ageing of modules that lead to changes in the track reconstruction. [...]

We investigate the discovery potential for long-lived axion-like particles produced in association with a top quark-antiquark pair at the (High-Luminosity) LHC. Compared to inclusive searches for a displaced vertex, top quark associated signals offer new trigger options and an extra handle to suppress background. [...]

The CMS Collaboration has reported in Run 2 two excesses above the background expectation in the search for a Beyond Standard Model Higgs boson decaying into tau leptons, at masses of 0.1 and 1.2 TeV and in the gluon fusion production process.This talk will present the strategy for a similar search with data collected by the CMS experiment in Run 3. First distributions and comparisons of data and Monte Carlo simulations will be shown for 2022 and 2023 data..
