We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a
comprehensive survey of standard model (SM) extensions. LLPs are a common prediction of …

The Majorana nature of neutrinos is strongly motivated from the theoretical and
phenomenological point of view. A plethora of neutrino mass models, known collectively as …

A bstract A search is presented for physics beyond the standard model (SM) using electron
or muon pairs with high invariant mass. A data set of proton-proton collisions collected by …

Abstract Particles beyond the Standard Model (SM) can generically have lifetimes that are
long compared to SM particles at the weak scale. When produced at experiments such as …

A bstract A search for new resonances decaying into a pair of jets is reported using the
dataset of proton-proton collisions recorded at\(\sqrt {s}\)= 13 TeV with the ATLAS detector at …

A bstract A search for narrow and broad resonances with masses greater than 1.8 TeV
decaying to a pair of jets is presented. The search uses proton-proton collision data at\(\sqrt …

The vector leptoquark representation, U μ=(3, 1, 2/3), was recently identified as an
exceptional single mediator model to address experimental hints on lepton flavor …

A bstract We study constraints from causality and unitarity on 2→ 2 graviton scattering in four-
dimensional weakly-coupled effective field theories. Together, causality and unitarity imply …

A bstract Searches for resonances decaying into pairs of jets are performed using proton-
proton collision data collected at\(\sqrt {s}= 13\) TeV corresponding to an integrated …

We present a three-site Pati–Salam gauge model able to explain the Standard Model flavor
hierarchies while, at the same time, accommodating the recent experimental hints of lepton …
