Search for charged massive long-lived particles.
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 sev...
متن کاملSearch 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 کاملSearch for long-lived charged massive particles with the D0 detector.
We search for long-lived charged massive particles using 1.1 fb;{-1} of data collected by the D0 detector at the Fermilab Tevatron pp[over ] Collider. Time-of-flight information is used to search for pair produced long-lived tau sleptons, gauginolike charginos, and Higgsino-like charginos. We find no evidence of a signal and set 95% C.L. cross section upper limits for staus, which vary from 0.3...
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 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)...
