A bstract Evidence for Higgs boson decay to a pair of muons is presented. This result
combines searches in four exclusive categories targeting the production of the Higgs boson …

A bstract The first measurement of the top quark pair (\(\textrm {t}\overline {\textrm {t}}\))
production cross section in proton-proton collisions at\(\sqrt {s}\)= 13. 6 TeV is presented …

A bstract The results of a search for direct pair production of top squarks and for dark matter
in events with two opposite-charge leptons (electrons or muons), jets and missing transverse …

A combination of searches for top squark pair production using proton–proton collision data
at a center-of-mass energy of 13\, Te V Te at the CERN LHC, corresponding to an integrated …

Dark matter (DM) simplified models are by now commonly used by the ATLAS and CMS
Collaborations to interpret searches for missing transverse energy (ET miss). The coherent …

A bstract We investigate the discovery potential for long-lived particles produced in
association with a top-antitop quark pair at the (High-Luminosity) LHC. Compared to …

A search for dark matter produced in association with top quarks in proton-proton collisions
at a center-of-mass energy of 13 TeV is presented. The data set used corresponds to an …

This book has been written as part of my habilitation at the University of Hamburg. It is
intended to serve graduate students and researchers to get familiar with the stateof-the-art of …

A bstract Several extensions of the Standard Model predict the production of dark matter
particles at the LHC. A search for dark matter particles produced in association with a dark …

Although weakly interacting massive particles (WIMPs) have long been among the most
studied and theoretically attractive classes of candidates for the dark matter of our universe …
