Nuclear target effect on dark matter detection rate

Expected event rates for a number of dark matter nuclear targets were calculated in the effective low-energy minimal supersymmetric standard model, provided the lightest neutralino is the dark matter Weakly Interacting Massive Particle (WIMP). These calculations allow direct comparison of sensitivities of different dark matter detectors to intermediate mass WIMPs expected from the measurements of the DArk MAtter (DAMA) experiment.Comment: 14 pages, 11 figures, revtex

On importance of dark matter for LHC physics

I would like to attract attention of the LHC high-energy physics community to non-accelerator, low-energy experiments, that are also very sensitive to new physics. My example concerns search for supersymmetric dark matter particles. It is shown that non-observation of the SUSY dark matter candidates with a high-accuracy detector can exclude large domains of the MSSM parameter space and, in particular, can make especially desirable collider search for light SUSY charged Higgs boson.Comment: latex, 12 pages, 9 figures, to be published in "Particles and Nuclei, Letters"; Talk given at the International symposium "LHC physics and detectors", Dubna, 28--30 June, 200

On leading charmed meson production in π\pi-nucleon interactions

It is shown that the D--meson, whose light quark is the initial-pion valence quark and whose charmed quark is produced in annihilation of valence quarks and has got a large enough momentum, is really a leading meson in reactions like $\pi^- p -> DX$. If such annihilation of valence quarks from initial hadrons is impossible there must be no distinct leading effect.Comment: 4 pages, 2.ps-figure
