A search for the standard model production of four top quarks (pp→ tt¯ tt¯) is reported using
single-lepton plus jets and opposite-sign dilepton plus jets signatures. Proton-proton …

A search for the pair production of heavy fermionic partners of the top quark with charge 5/3
(X5/3) is performed in proton-proton collisions at a center-of-mass energy of 13 TeV with the …

A search is presented for excited electrons and muons in ℓℓγ final states at the LHC. The
search is based on a data sample corresponding to an integrated luminosity of 35.9 fb⁻ ¹ of …

A search is presented for excited electrons and muons in $\ell\ell\gamma $ final states at the

A search for excited electrons produced in pp collisions at s= 13 Te via a contact interaction
qq¯→ ee is presented. The search uses 36.1 fb of data collected in 2015 and 2016 by the …

A new search signature for excited leptons is explored. Excited muons are sought in the
channel pp→ µµ∗→ µµ jet jet, assuming both the production and decay occur via a contact …

Results are presented of a search for compositeness in electrons and muons using a data
sample of pp collisions at a center-of-mass energy collected with the CMS detector at the …

Results are reported from a search for the anomalous production of highly boosted Z bosons
with large transverse momentum and decaying to μ+ μ− μ+ μ−. Such Z bosons may be …
