Search for Milli-Charged particles from the Sun at IceCube

Updated bounds on milli-charged particles

We update the bounds on fermions with electric charge e and mass m . For m . me we find 10−15 . < 1 is excluded by laboratory experiments, astrophysics and cosmology. For larger masses, the limits are less restrictive and depend on m . For milli-charged neutrinos, the limits are stronger, especially if the different flavors mix as suggested by current experimental evidence.

The Search for Charged Massive Supersymmetric Particles at the LHC

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...

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 ...

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...
