Axionic dark matter signatures in various halo models

In the present work we study possible time signatures Axion Dark Matter searches employing resonant cavities for various halo models. We study in particular the time dependence of the resonance width (modulation) and possible asymmetries in directional experiments.Comment: 15 pages, 9 figure

Measurement of the Muon Anomalous Magnetic Moment to 0.7 ppm

The experimental method together with the analysis method and results of the data taken in 2000 and prospects of the muon anomalous magnetic and electric dipole moment experiments are presented here.Comment: 12 pages, 20 figures. Proceedings of my plenary talk at ICHEP02, Amsterdam, 31 July 200

Bosonic Coherent Motions in the Universe

We mini-review the role of fundamental spin-0 bosons as bosonic coherent motion (BCM) in the Universe. The fundamental spin-0 bosons have the potential to account for the baryon number generation, cold dark matter (CDM) via BCM, dark energy, and inflation. Among these, here we focus on the CDM possibility because it can be experimentally tested with the current experimental techniques. We also comment briefly on the panoply of the other roles of spin-0 bosons.Comment: 15 pages, 7 figure

Dark matter and Higgs boson physics

A vector-like colorless fermion doublet and a singlet added to the Standard Model allow a consistent interpretation of dark matter in terms of the lightest neutral particle, as they may help in obtaining successful gauge coupling unification. We analyze in detail the mass range of the lightest neutral particle below the W mass, i.e. in a range of the parameters where the physics of the Standard Model Higgs boson may be substantially affected either directly or indirectly.Comment: 17 pages, 7 figures. v3: published version (small corrections
