The Super-GUT CMSSM Revisited / Ellis, John (CERN ; King's Coll. London) ; Evans, Jason L. (Korea Inst. Advanced Study, Seoul) ; Mustafayev, Azar (Minnesota U., Theor. Phys. Inst.) ; Nagata, Natsumi (Minnesota U., Theor. Phys. Inst.) ; Olive, Keith A. (Minnesota U., Theor. Phys. Inst.)
We revisit minimal supersymmetric SU(5) grand unification (GUT) models in which the soft supersymmetry-breaking parameters of the minimal supersymmetric Standard Model (MSSM) are universal at some input scale, $M_{in}$, above the supersymmetric gauge coupling unification scale, $M_{GUT}$. As in the constrained MSSM (CMSSM), we assume that the scalar masses and gaugino masses have common values, $m_0$ and $m_{1/2}$ respectively, at $M_{in}$, as do the trilinear soft supersymmetry-breaking parameters $A_0$.

Monojets and mono-photons from light higgsino pair production at LHC14 / Baer, Howard (Oklahoma U.) ; Mustafayev, Azar (Hawaii U. ; CERN) ; Tata, Xerxes (Hawaii U.)
Naturalness arguments imply the existence of higgsinos lighter than 200-300 GeV. However, because these higgsinos are nearly mass degenerate, they release very little visible energy in their decays, and signals from electroweak higgsino pair production typically remain buried under Standard Model backgrounds.

Strong moduli stabilization and phenomenology / Dudas, Emilian (Orsay, LPT ; Ecole Polytechnique, CPHT ; CERN) ; Linde, Andrei (Stanford U., Phys. Dept. ; Stanford U., ITP) ; Mambrini, Yann (Orsay, LPT) ; Mustafayev, Azar (Hawaii U. ; Minnesota U., Theor. Phys. Inst.) ; Olive, Keith A. (Minnesota U., Theor. Phys. Inst.)
We describe the resulting phenomenology of string theory/supergravity models with strong moduli stabilization. The KL model with F-term uplifting, is one such example. [...]

Relating the CMSSM and SUGRA models with GUT scale and Super-GUT scale Supersymmetry Breaking / Dudas, Emilian (Orsay, LPT ; Ecole Polytechnique, CPHT ; CERN) ; Mambrini, Yann (Orsay, LPT) ; Mustafayev, Azar (Minnesota U., Theor. Phys. Inst.) ; Olive, Keith A. (Minnesota U., Theor. Phys. Inst.)
While the constrained minimal supersymmetric standard model (CMSSM) with universal gaugino masses, $m_{1/2}$, scalar masses, $m_0$, and A-terms, $A_0$, defined at some high energy scale (usually taken to be the GUT scale) is motivated by general features of supergravity models, it does not carry all of the constraints imposed by minimal supergravity (mSUGRA). In particular, the CMSSM does not impose a relation between the trilinear and bilinear soft supersymmetry breaking terms, $B_0 = A_0 - m_0$, nor does it impose the relation between the soft scalar masses and the gravitino mass, $m_0 = m_{3/2}$.

Constrained Supersymmetric Flipped SU(5) GUT Phenomenology / Ellis, John (CERN ; King's Coll. London) ; Mustafayev, Azar (Minnesota U.) ; Olive, Keith A (Minnesota U. ; Stanford U. ; SLAC)
We explore the phenomenology of the minimal supersymmetric flipped SU(5) GUT model (CFSU(5)), whose soft supersymmetry-breaking (SSB) mass parameters are constrained to be universal at some input scale, $M_{in}$, above the GUT scale, $M_{GUT}$. We analyze the parameter space of CFSU(5) assuming that the lightest supersymmetric particle (LSP) provides the cosmological cold dark matter, paying careful attention to the matching of parameters at the GUT scale.

Resurrecting No-Scale Supergravity Phenomenology / Ellis, John (CERN) ; Mustafayev, Azar (Minnesota U., Theor. Phys. Inst.) ; Olive, Keith A. (Minnesota U., Theor. Phys. Inst.)
In the context of phenomenological models in which the soft supersymmetry-breaking parameters of the MSSM become universal at some unification scale, M_{in}, above the GUT scale, \mgut, it is possible that all the scalar mass parameters m_0, the trilinear couplings A_0 and the bilinear Higgs coupling B_0 vanish simultaneously, as in no-scale supergravity. Using these no-scale inputs in a renormalization-group analysis of the minimal supersymmetric SU(5) GUT model, we pay careful attention to the matching of parameters at the GUT scale. [...]

What if Supersymmetry Breaking Unifies beyond the GUT Scale? / Ellis, John (CERN) ; Mustafayev, Azar (Minnesota U., Theor. Phys. Inst.) ; Olive, Keith A. (Minnesota U., Theor. Phys. Inst.)
