With the establishment and maturation of the experimental programs searching for new
physics with sizeable couplings at the LHC, there is an increasing interest in the broader …

This article is a pedagogical review of searches for long-lived particles at the LHC. It is
primarily aimed at experimentalists and theorists seeking to initiate and/or deepen their …

A bstract A search for long-lived particles decaying into hadrons is presented. The analysis
uses 139 fb− 1 of pp collision data collected at\(\sqrt {s}\)= 13 TeV by the ATLAS detector at …

A search for charged leptons with large impact parameters using 139 fb− 1 of s= 13 TeV pp
collision data from the ATLAS detector at the LHC is presented, addressing a long-standing …

A search for long-lived particles (LLPs) produced in decays of standard model (SM) Higgs
bosons is presented. The data sample consists of 137 fb-1 of proton-proton collisions at s …

This is the Snowmass2021 Energy Frontier (EF) Beyond the Standard Model (BSM) report. It
combines the EF topical group reports of EF08 (Model-specific explorations), EF09 (More …

Exotic decays of the Standard Model (SM)-like Higgs boson into beyond-the-SM particles
are predicted in a wide range of well-motivated theories. The enormous samples of Higgs …

A bstract A novel search for exotic decays of the Higgs boson into pairs of long-lived neutral
particles, each decaying into a bottom quark pair, is performed using 139 fb− 1 of\(\sqrt {s}\) …

This paper presents a search for hypothetical massive, charged, long-lived particles with the
ATLAS detector at the LHC using an integrated luminosity of 139 fb $^{-1} $ of proton-proton …

A search for long-lived particles (LLPs) decaying in the CMS muon detectors is presented. A
data sample of proton-proton collisions at $\sqrt {s} $= 13 TeV corresponding to an …
