 | Gondolo, Paolo | Cosmic ray positron excess and neutralino dark matter | Using a new instrument, the HEAT Collaboration has confirmed the excess of cosmic ray positrons that they first detected in 1994. We explore the possibility that this excess is due to the annihilation of neutralino dark matter in the galactic halo. We confirm that neutralino annihilation can produ... | Neutralinos; Supersymmetric models; Positron flux; Annihilations | 2002-02 |

 | DeTar, Carleton | Lattice calculation of heavy-light decay constants with two flavors of dynamical quarks | We present results for f B , f Bs , f D , f Ds and their ratios in the presence of two flavors of light sea quarks (Nf52). We use Wilson light valence quarks and Wilson and static heavy valence quarks; the sea quarks are simulated with staggered fermions. Additional quenched simulations with nonpe... | Wilson quarks; Chiral perturbation | 2002-11 |

 | Gondolo, Paolo | Recoil momentum spectrum in directional dark matter detectors | Directional dark matter detectors will be able to record the recoil momentum spectrum of nuclei hit by dark matter WIMPs. We show that the recoil momentum spectrum is the Radon transform of the WIMP velocity distribution. This allows us to obtain analytic expressions for the recoil spectra of a va... | Recoil momentum spectrum; Radon transform; WIMP; Weakly interacting massive particles; Velocity distribution | 2002-11 |
