It has been argued that requiring low electroweak fine-tuning (EWFT) along with a (partial) decoupling solution to the SUSY flavor and CP problems leads sparticle mass spectra characterized by light Higgsinos at 100-300 GeV, sub-TeV third generation scalars, gluinos few TeV multi-TeV first/second scalars (natural SUSY). We show starting trilinear soft breaking terms, natural spectrum can be generated radiatively via renormalization group running effects. Using complete 1-loop effective...
The ATLAS and CMS collaborations have reported an excess of events in the $\ensuremath{\gamma}\ensuremath{\gamma}$, $Z{Z}^{*}\ensuremath{\rightarrow}4\ensuremath{\ell}$ $W{W}^{*}$ search channels at invariant mass $m\ensuremath{\simeq}125\text{ }\text{ }\mathrm{GeV}$, which could be first evidence for long-awaited Higgs boson. We investigate consequences requiring ${m}_{h}\ensuremath{\simeq}125\text{ }\mathrm{GeV}$ both minimal supergravity 2-parameter nonuniversal supersymmetric models. In...
Models of natural supersymmetry seek to solve the little hierarchy problem by positing a spectrum light higgsinos m_0 leads automatic cancellations during renormalization group (RG) running, and radiatively-induced low fine-tuning at electroweak scale. Coupled with large mixing in top squark sector, RNS allows for 3-10% level TeV-scale squarks 125 GeV Higgs scalar h. The model least partial solution SUSY flavor, CP gravitino problems since first/second generation scalars (and gravitino) may...
ISAJET is a Monte Carlo event generator for $pp$, $\bar pp$, and $e^+e^-$ interactions at high energies. This document summarizes the physics underlying program describes how to use it.
Working within the framework of minimal supergravity model with gauge coupling unification and radiative electroweak symmetry breaking, we evaluate cosmological relic density from lightest neutralinos produced in early universe. Our numerical calculation is distinct that it involves direct evaluation neutralino annihilation cross sections using helicity amplitude techniques, thus avoids usual expansion as a power series terms velocity. Thus, our includes relativistic Boltzmann averaging,...

It has recently been pointed out that viable sparticle mass spectra can be generated in Yukawa unified SO(10) supersymmetric grand models consistent with radiative breaking of electroweak symmetry. Model solutions are obtained only if $\tan\beta \sim 50$, $\mu <0$ and positive $D$-term contributions to scalar masses from gauge symmetry used. In this paper, we attempt systematize the parameter space regions where obtained. We go on calculate relic density neutralinos as a function space. No...
