Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at weak scale. When produced experiments such as Large Hadron Collider (LHC) CERN, these long-lived (LLPs) decay far from interaction vertex of primary proton-proton collision. Such LLP signatures distinct those promptly decaying targeted by majority searches for new physics LHC, often requiring customized techniques identify, example, significantly displaced vertices, tracks with...

Several theories beyond the Standard Model (BSM) predict heavy neutral leptons, or long-lived particles with unique signatures which are difficult to reconstruct. Another area of interest vector-like quarks lie at heart many extensions seeking address Hierarchy Problem, as they can naturally cancel mass divergence for Higgs boson. New results these BSM searches from ATLAS and CMS experiments LHC presented.

Searches of vector-like leptons, heavy Majorana neutrinos, and leptoquarks, using the complete 20.3 fb−1 luminosity sample pp collisions collected at 8 TeV by ATLAS detector, are presented in this review. Signatures based on number high-momentum jets, b-tagged missing momentum size. No excess was observed any channel, limits set cross sections, masses couplings, extending coverage from previous studies considered models.
