Search for massive, long-lived particles using multitrack displaced vertices or displaced lepton pairs in pp collisions at s√ = 8 TeV with the ATLAS detector
(American Physical Society, 2015-10)
Many extensions of the Standard Model posit the existence of heavy particles with long lifetimes. This article presents the results of a search for events containing at least one long-lived particle that decays at a ...
Search for heavy long-lived multi-charged particles in pp collisions at s√=8 TeV using the ATLAS detector
(Springer, 2015-08)
A search for heavy long-lived multi-charged particles is performed using the ATLAS detector at the LHC. Data collected in 2012 at √ s = 8 TeV from pp collisions corresponding to an integrated luminosity of 20.3 fb−1 are ...
Direct detection of Kaluza-Klein particles in neutrino telescopes
(AMER PHYSICAL SOC, 2008)
In theories with universal extra dimensions, all standard model fields propagate in the bulk and the lightest state of the first Kaluza-Klein (KK) level can be made stable by imposing a Z(2) parity. We consider a framework ...
A rationale for long-lived quarks and leptons at the LHC: low energy flavour theory
(SPRINGERNEW YORK, 2012)
In the framework of gauged flavour symmetries, new fermions in parity symmetric representations of the standard model are generically needed for the compensation of mixed anomalies. The key point is that their masses are ...
Triggers for displaced decays of long-lived neutral particles in the ATLAS detector
(IOP Publishing, 2013-07)
A set of three dedicated triggers designed to detect long-lived neutral particles decaying throughout the ATLAS detector to a pair of hadronic jets is described. The efficiencies of the triggers for selecting displaced ...
Search for long-lived particles decaying into electron or photon pairs with the D0 detector
(2008-09-12)
In this Letter we report on a search for long-lived particles that decay into final states with two electrons or photons. Such long-lived particles arise in a variety of theoretical models, such as hidden valleys and ...

Search for charged massive long-lived particles
(2012-03-21)
We report on a search for charged massive long-lived particles (CMLLPs), based on 5.2fb -1 of integrated luminosity collected with the D0 detector at the Fermilab Tevatron pp̄ collider. We search for events in which one ...
Search for new long-lived particles at root s=13 TeV
(Elsevier B.V., 2018-05-10)
A search for long-lived particles was performed with data corresponding to an integrated luminosity of 2.6 fb(-1) collected at a center-of-mass energy of 13 TeV by the CMS experiment in 2015. The analysis exploits two ...
Search for metastable heavy charged particles with large ionisation energy loss in pp collisions at s√=8 TeV using the ATLAS experiment
(Springer, 2015-09)
Many extensions of the Standard Model predict the existence of charged heavy long-lived particles, such as R-hadrons or charginos. These particles, if produced at the Large Hadron Collider, should be moving non-relativistically ...
