Leveraging the ALICE/L3 cavern for long-lived particle searches

R-Hadron and long lived particle searches at the LHC

If long lived charged particles exist, and produced at the LHC, they may travel with velocity significantly slower than the speed of light. This unique signature was not considered during the design of the LHC experiments, ATLAS and CMS. As a result, hardware and trigger capabilities need to be evaluated. Model independent approaches for finding long lived particles with the LHC experiments are...

Searches for Long-lived Particles at the Tevatron Collider

Several searches for long-lived particles have been performed using data from pp̄ collisions from Run II at the Tevatron. In most cases, new analysis techniques have been developed to carry out each search and/or estimate the backgrounds. These searches expand the discovery potential of the CDF and D0 experiments to new physics that may have been missed by traditional search techniques. This rev...

Prospects of searches for neutral, long-lived particles that decay to photons using timing at CDF

1550-7998=20 We present the prospects of searches for neutral, long-lived particles that decay to photons using their time of arrival measured with a newly installed timing system on the electromagnetic calorimeter (EMTiming) of the Collider Detector at Fermilab (CDF). A Monte Carlo simulation shows that EMTiming can provide separation between decay photons from neutral, long-lived particles an...

New Particle Searches

New particle searches are dominated by LEP, whose results comemostly from data up to 189 GeV except for some updates from 1999 data up to 196 GeV. Combined results from the four LEP experiments also exist on some subjects and are denoted ADLO. After a brief outline of the searches on exotic particles, results on supersymmetric particles and Higgs bosons are detailed. All exclusion limits are at...
