This is the third out of five chapters of the final report [1] of the Workshop on Physics at HL-
LHC, and perspectives on HE-LHC [2]. It is devoted to the study of the potential, in the …

A bstract A generic search for anomalous production of events with at least three charged
leptons is presented. The data sample consists of pp collisions at\(\sqrt {s}= 8\) TeV collected …

A bstract A search for a heavy resonance decaying into a top quark and antiquark\(\left
(\mathrm {t}\overline {\mathrm {t}}\right)\) pair is performed using proton-proton collisions …

A coherent description of the ATLAS and CMS program of searches for physics beyond the
Standard Model of particle physics (except supersymmetry) is subject of this review. The …

A bstract Results are presented from a search for events containing an excited lepton
(electron or muon) produced in association with an ordinary lepton of the same flavor and …

A search for excited electrons produced in pp collisions at\(\sqrt {s}\)= 13\(\text {Te}\text {V}\)
via a contact interaction\(q {\bar {q}}\rightarrow ee^*\) is presented. The search uses 36.1 …

We investigate the search for heavy Majorana neutrinos stemming from a composite model
scenario at the upcoming LHC Run II at a centre of mass energy of 13 TeV. While previous …

The grand unified group E 6 is a predictive scheme for physics beyond the standard model
(SM). It offers the possibility of extra Z bosons, new vectorlike fermions, sterile neutrinos, and …

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 …

The electron–proton collisions collected by the H1 and ZEUS experiments at HERA
comprise a unique particle physics data set, and a comprehensive range of measurements …
