Expanding the parameter space of natural supersymmetry
Journal of High Energy Physics, 2020 SUSY/SUGRA models with naturalness defined via small μ are constrained due to experiment on the relic density and the experimental limits on the WIMP-proton cross-section and WIMP annihilation cross-section from indirect detection experiments ...

Long-lived stau, sneutrino dark matter and right-slepton spectrum
Journal of High Energy Physics, 2018 The minimal supersymmetric (SUSY) standard model (MSSM) augmented by right chiral sneutrinos may lead to one such sneutrino serving as the lightest supersymmetric particle and a non-thermal dark matter candidate, especially if neutrinos have Dirac masses

Supersymmetry Phenomenology: A Microreview
, 1995 We briefly review the current status and future prospects for supersymmetry searches at colliders, and discuss strategies by which further information about sparticle properties may be obtained at the LHC.

How light a higgsino or a wino dark matter can become in a compressed scenario of MSSM
Journal of High Energy Physics, 2017 Higgsinos and Wino have strong motivations for being Dark Matter (DM) candidates in supersymmetry, but their annihilation cross sections are quite large.

Developments in Supersymmetry Phenomenology
, 1998 We survey strategies generally employed for SUSY discovery at colliders and then discuss how these may have to be altered for SUSY searches at the Tevatron if $\tanβ$ is large. We also discuss the reach of the Tevatron and the LHC in gauge-mediated SUSY breaking scenarios, assuming that the NLSP decays into photons.

Deciphering the MSSM Higgs mass at future hadron colliders
Journal of High Energy Physics, 2017 Future hadron colliders will have a remarkable capacity to discover massive new particles, but their capabilities for precision measurements of couplings that can reveal underlying mechanisms have received less study. In this work we study the capability

Phenomenological constraints on broken supersymmetry
Physics Letters B, 1978 Abstract We show that the existence of massless color octet quarks, which appear in a class of broken supersymmetric field theories, implies the existence of additional light (⪅ 1 GeV) unstable hadrons with large (⪆ 10 μb) production cross sections. We estimate the half-life for these states to be less than 10−8 s. If it is greater than 10°10 s,

The current status of fine-tuning in supersymmetry
Journal of High Energy Physics, 2020 In this paper, we minimize and compare two different fine-tuning measures in four high-scale supersymmetric models that are embedded in the MSSM. In addition, we determine the impact of current and future dark matter direct detection and collider ...

Constraining slepton and chargino through compressed top squark search
Journal of High Energy Physics, 2018 We examine the compressed mass spectrum with sub-TeV top squark t˜ $$ \left(\tilde{t}\right) $$ as lightest colored (s)particle in natural supersymmetry (SUSY). Such spectra are searched along with an additional hard jet, not only to boost the soft decay
