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 کاملPair-production of charged Dirac particles on charged Nariai and ultracold black hole manifolds
Spontaneous loss of charge by charged black holes by means of pair-creation of charged Dirac particles is considered. We provide three examples of exact calculations for the spontaneous discharge process for 4D charged black holes by considering the process on three special nonrotating de Sitter black hole backgrounds, which allow to bring back the problem to a Kaluza-Klein reduction. Both the ...
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 کاملCompare charged and uncharged particles leakage of plasma focus for medical radioisotopes production
In this study, to calculate the radioactivity of radioisotopes such as 11C, 15O, 18F and 123,124I in a focus plasma device for the production of medical radioisotopes, the particles of neutrons and protons with cubic targets of Nitrogen, Xenon, Carbon and a solid natural Boron is used. Particles energy are at the input of the program from 1MeV to 10MeV. Also, the total yield coefficient is cons...
