A Search for Charged Massive Stable Particles
standard model. The hypothetical particles are assumed to be pair-produced in pp̄ collisions giving a signature of two reconstructed muon-like objects with high invariant mass and time-offlights indicative of heavy particles. Since no excess over background is observed, cross-section limits for the pair-production of stable staus and charginos are set. Mass limits of 140 GeV for a higgsino-like ...
متن کاملMicrobeams of heavy charged particles.
We have established a single cell irradiation system, which allows selected cells to be individually hit with defined number of heavy charged particles, using a collimated heavy-ion microbeam apparatus at JAERI-Takasaki. This system has been developed to study radiobiological processes in hit cells and bystander cells exposed to low dose and low dose-rate high-LET radiations, in ways that canno...
متن کاملThe Search for Heavy Particles
Direct and indirect evidence for the existence of a new heavy quark b and of new heavy neutral leptons eke and =/tip can be sought in neutrino and e+escattering. These particles are expected to have right-handed currents. Discussion is given on the characteristics, production and decay of hadrons such as b6, & and &, and of the massive neutral leptons. -Muon number violation with and without ?N...
متن کاملSearch 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...
