Increasingly stringent limits from LHC searches for new physics, coupled with lack of
convincing signals of weakly interacting massive particle (WIMP) in dark matter searches …

A bstract Indirect detection constraints on gamma rays (both continuum and lines) have set
strong constraints on wino dark matter. By combining results from Fermi-LAT and HESS, we …

We review the status of axino dark matter. Two hierarchy problems, the strong CP problem
and the gauge hierarchy problem, have led to introducing into particle physics a …

We examine updated prospects for detecting WIMPs in supersymmetric models via direct
and indirect dark matter search experiments. We examine several historical and also still …

A bstract Nowadays, the cosmological moduli problem (CMP) comes in three parts: 1.
potential violation of Big-Bang nucleosynthesis (BBN) constraints from late decaying moduli …

A bstract Relativistic axions are good candidates for the dark radiation for which there are
mounting observational hints. The primordial decays of heavy fields produce axions which …

We examine mixed axion/neutralino cold dark matter production in the SUSY DFSZ axion
model where an axion superfield couples to Higgs superfields. We calculate a wide array of …

A bstract We evaluate the amount of fine-tuning in constrained versions of the minimal
supersymmetric standard model (MSSM), with different boundary conditions at the GUT …

The requirement of electroweak naturalness in supersymmetric (SUSY) models of particle
physics necessitates light higgsinos not too far from the weak scale characterized by m …

A bstract Radiatively-driven natural supersymmetry (RNS) potentially reconciles the Z and
Higgs boson masses close to~ 100 GeV with gluinos and squarks lying beyond the TeV …
