“…A wide range of signal scenarios with different mass splittings between the stop, the lightest neutralino and possible intermediate gauginos or higgsinos is considered, including cases where the $W$-bosons or the top-quarks are off-shell. The analysis also targets the production of dark matter in association with a pair of top-quarks using the same final state. …”

“…These signatures include generic quark and gluon jets, as well as jets originating from b-quarks or the decay of massive particles (such as electroweak bosons or top quarks). Additionally missing transverse momentum from non-interacting particles provides an interesting probe in the search for new physics beyond the Standard Model. …”

“…The argument crucially relies on the study by Kalai and Kindler (2014) of noise stability and sensitivity for systems of non-interacting bosons. This study is built on the theory of noise stability and noise sensitivity of Boolean functions developed by Benjamini, Kalai, and Schramm (1999). …”

“…This note describes how the counting of $Z\rightarrow \ell \ell$ bosons can be used as a relative luminometer, and quantifies the internal consistency of the method by comparing the luminosities obtained in the $Z \rightarrow e^+e^-$ and $Z \rightarrow \mu^+\mu^-$ channels. …”

“…The results are interpreted with models involving top squarks that decay to displaced leptons via R-parity-violating interactions, a gauge-mediated supersymmetry breaking model with lepton superpartners that decay to gravitinos and displaced leptons, and a model involving exotic Higgs bosons that decay to long-lived scalars, which in turn decay to displaced leptons. …”

“…The collection of more than 150 fb$^{-1}$ of data at the Large Hadron Collider (LHC) allows for the exploration of rare processes predicted in the Standard Model (SM) that were previously inaccessible, such as, the production of triple gauge bosons. The discovery of triboson production was announced by the CMS Collaboration in April, 2020 and marks an important achievement in SM physics. …”

The reconstruction of such objects sets the calorimeter performance requirements in terms of shower containment, energy resolution and granularity. …”

“…The electron is an ideal probe of the proton structure because it provides the unmatched precision of the electromagnetic interaction, as the virtual photon or vector bosons probe the proton structure in a clean environment, the kinematics of which is uniquely determined by the electron beam and the scattered lepton, or the hadronic final state accounting appropriately for radiation. …”
