چکیده
We report on a search for charged massive long-lived particles (CMLLPs), based on 5.2 fb(-1) of integrated luminosity collected with the D0 detector at the Fermilab Tevatron pp collider. We search for events in which one or more particles are reconstructed as muons but have speed and ionization energy loss (dE/dx) inconsistent with muons produced in beam collisions. CMLLPs are predicted in several theories of physics beyond the standard model. We exclude pair-produced long-lived gauginolike charginos below 267 GeV and Higgsino-like charginos below 217 GeV at 95% C.L., as well as long-lived scalar top quarks with mass below 285 GeV.

Search for Long-lived Charged Massive Particles at CDF
A search for long-lived charged massive particles in CDF's Run1b data sample is presented. The search looks for highly ionizing tracks which would result from slowly moving massive particles. We search for strongly produced particles using a stable color triplet quark as a reference model, and a separate search was performed for weakly produced particles using long-lived sleptons in GaugeMediat...
متن کاملA search for charged massive long - lived particles at D 0
Results are presented on a search for charged massive long-lived particles (CMLLPs), based on 5.2 f b 1 of integrated luminosity collected with the D0 detector at the Fermilab Tevatron pp col-lider. CMLLPs are predicted by several theories in beyond the standard model scenarios. They behave like muons but are slower and highly ionizing. In the absence of any CMLLP signature we have put limits o...
متن کاملSearches 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...
متن کاملSearch for long-lived massive neutrinos in Z decays.
We search for events in the Mark II detector at SLC with the topology of a 2 boson decaying into a pair of long-lived, massive particles. No events that are consistent with the search hypothesis are found. Interpreting the long-lived particle as a sequential Dirac neutrino v4 of the fourth generation, we exclude at the 95% confidence level a significant range of mixing matrix elements of v4 to ...
متن کاملMeasuring lifetimes of long-lived charged massive particles stopped in LHC detectors.
Long-lived charged massive particles (CHAMPs) appear in various particle physics models beyond the standard model. In this Letter, we discuss the prospects for studying the stopping and decaying events of such long-lived CHAMPs at the LHC detectors, and show that the lifetime measurement (and the study of decay products) is possible with the LHC detectors for a wide range of the lifetime O(0.1)...

We discuss possibilities of detecting neutral and charged long-lived particles with the upgraded DØ detector in Run II of the Fermilab Tevatron accelerator, using photon pointing, dE/dx, and time-of-flight techniques. Long-lived neutral or charged massive particles appear in many extensions of the MSSM. There are two main scenarios which result in a long lifetime of some of the SUSY partners. I...
