neutralino การใช้

• Neutralino dark matter could be observed experimentally in nature either indirectly or directly.
• Was Prof . Sumner the first scientist who proposed that CDM could be the hypothetical neutralino?
• Typically the dark matter candidate of the MSSM is an admixture of the electroweak gauginos and Higgsinos and is called a neutralino.
• One of the two proposed categories of what cold dark matter consists of is weakly interacting massive particles, of which the leading candidate is the neutralino.
• Neutralinos and sleptons were expected to be quite light, with the lightest neutralino and the lightest stau most likely to be found between 100 and 150 GeV.
• These experiments have begun to probe interesting supersymmetric parameter space, excluding some models for neutralino dark matter, and upgraded experiments with greater sensitivity are under development.
• For indirect observation, gamma ray and neutrino telescopes look for evidence of neutralino annihilation in regions of high dark matter density such as the galactic or solar centre.
• In many supersymmetric Standard Models there is a heavy stable particle ( such as neutralino ) which could serve as a weakly interacting massive particle ( WIMP ) dark matter candidate.
• If experimental evidence confirms supersymmetry in the form of supersymmetric particles such as the neutralino that is often believed to be the lightest superpartner, some people believe this would be a major boost to string theory.
• In R-parity conserving models, the lightest neutralino is stable and all supersymmetric cascades decays end up decaying into this particle which leaves the detector unseen and its existence can only be inferred by looking for unbalanced momentum in a detector.
• In R-parity conserving models, the lightest neutralino is stable and all supersymmetric cascade-decays end up decaying into this particle which leaves the detector unseen and its existence can only be inferred by looking for unbalanced momentum in a detector.
• From 2003-2015, WMAP's and Planck's dark matter density measurements have strongly constrained supersymmetry models, which, if they explain dark matter, have to be tuned to invoke a particular mechanism to sufficiently reduce the neutralino density.
• Depending on the specific details of the SUSY model and the mass hierarchy of the sparticles, the stop might decay into a bottom quark and a chargino, with a subsequent decay of the chargino into the lightest neutralino ( which is often the lightest supersymmetric particle ).
• This rate depends on the underlying model describing the properties of the WIMP . One of the most popular candidates for a WIMP is the Lightest Supersymmetric Particle ( LSP ) or neutralino from pb and 10 & minus; 6 pb, making WIMP-nucleon interactions a rare event.
• But this week, the team made a paper describing the possible detection of the particle, variously called a neutralino and a weakly interacting, massive particle, or WIMP, available on its public Web site ( http : / / www . lngs . infn . it / ).
• Apart from this astro-particle physics aspect, the ANTARES telescope may also tackle some fundamental problems in particle physics, such as the search for dark matter in the form of neutralino annihilation in the sun ( normal solar neutrinos being outside the energy range of ANTARES ) or the CDMS and at the LHC . Detection of neutralino signals would also confirm supersymmetry, but is not generally considered very likely at the ANTARES sensitivity level.
