Abstract We discribe the construction status of ZEPLIN II detector, a 30-kg two-phase discriminating xenon detector to be installed in Boulby Mine, UK, for the direct detection of WIMP dark matter. Both scintillation and ionization will be measure in order to discriminate the radioactive background. ZEPLIN-II will have very high radioactive-background rejection efficiency. We will also discuss the study of ton scale ZEPLIN IV. The ZEPLIN program is a collaborative work of UCLA, TAMU, UKMDMC…

Limits on spin-dependent WIMP-nucleon cross-sections from the first ZEPLIN-II data
The first underground data run of the ZEPLIN-II experiment has set a limit on the nuclear recoil rate in the two-phase xenon detector for direct dark matter searches. In this Letter the results from
Review of Liquid Argon Detector Technologies in the Neutrino Sector
Liquid Argon (LAr) is one of the most widely used scintillators in particle detection, due to its low cost, high availability and excellent scintillation properties. A large number of experiments in
Scintillation response of liquid xenon to low energy nuclear recoils
Liquid Xenon (LXe) is expected to be an excellent target and detection medium to search for dark matter in the form of Weakly Interacting Massive Particles (WIMPs). We have measured the scintillation
Prospects for the Detection of SUSY Dark Matter
We present the status of the search for dark matter particles. The different methods include cryogenic detectors and liquid Noble gas detectors such as Xenon (ZEPLIN, etc.). We review the evidence
Indirect, direct and collider detection of neutralino dark matter in the minimal supergravity model
We examine the prospects for supersymmetry discovery in the minimal supergravity (mSUGRA) model via indirect detection of neutralino dark matter. We investigate rates for muon detection in neutrino
Dark matter, light top squarks, and electroweak baryogenesis
We examine the neutralino relic density in the presence of a light top squark, such as the one required for the realization of the electroweak baryogenesis mechanism, within the minimal
The Dark Universe: The Search for Dark Matter and the Nature of Dark Energy
In these lectures we discuss the evidence for dark matter in the universe and in galaxies. The search for WIMP dark matter is discussed in detail, including the current search. We describe the ZEPLIN
Supersymmetric Origin of Matter
The minimal supersymmetric extension of the standard model (MSSM) can provide the correct neutralino relic abundance and baryon number asymmetry of the universe. Both may be efficiently generated in
Exploring the BWCA (Bino-Wino co-annihilation) scenario for neutralino dark matter
In supersymmetric models with non-universal gaugino masses, it is possible to have opposite-sign SU(2) and U(1) gaugino mass terms. In these models, the gaugino eigenstates experience little mixing
Target dark matter detection rates in models with a well-tempered neutralino
In the post-LEP2 era, and in light of recent measurements of the cosmic abundance of cold dark matter (CDM) in the universe from WMAP, many supersymmetric models tend to predict (i) an overabundance
