SUSY stops at a bump

  title={SUSY stops at a bump},
  author={Christopher Brust and Andrey Katz and Raman Sundrum},
  journal={Journal of High Energy Physics},
A bstractWe discuss collider signatures of the “natural supersymmetry” scenario with baryon-number violating R-parity violation. We argue that this is one of the few remaining viable incarnations of weak scale supersymmetry consistent with full electroweak naturalness. We show that this intriguing and challenging scenario contains distinctive LHC signals, resonances of hard jets in conjunction with relatively soft leptons and missing energy, which are easily overlooked by existing LHC searches… Expand

RPV stops bump off the background
We study the 8 TeV LHC reach on pair produced heavy flavored di-jet resonances. Motivated by theories of R-parity violation in supersymmetry we concentrate on a final state with two b-jets and twoExpand
LHC coverage of RPV MSSM with light stops
A bstractWe examine the sensitivity of recent LHC searches to signatures of supersymmetry with R-parity violation (RPV). Motivated by naturalness of the Higgs potential, which would favor lightExpand
Natural SUSY in Plain Sight
The basic principle of naturalness has driven the majority of the LHC program, but so far all searches for new physics beyond the SM have come up empty. On the other hand, existing measurements of SMExpand
Sensitivity of an Upgraded LHC to R-Parity Violating Signatures of the MSSM
We present a sensitivity study for the pair-production of supersymmetric particles which decay through R-parity violating channels. As the scope of possible RPV signatures is very broad, the reach ofExpand
Boosting searches for natural supersymmetry with R -parity violation via gluino cascades
In the presence of even minuscule baryonic R-parity violation, the stop can be the lightest superpartner and evade LHC searches because it decays into two jets. In order to cover this interestingExpand
Probing natural SUSY from stop pair production at the LHC

SUSY: Quo Vadis?
Given that there is currently no direct evidence for supersymmetric particles at the LHC it is timely to re-evaluate the need for low scale supersymmetry and to ask whether it is likely to beExpand
Radiative Natural Supersymmetry with Mixed Axion/Higgsino Cold Dark Matter
Models of natural supersymmetry seek to solve the little hierarchy problem by positing a spectrum of light higgsinos \( m 0 leads to natural cancellations during RG running, and to radiativelyExpand
The Light Gluino Gap

Least constrained supersymmetry with R -parity violation
The strong constraints on the R-parity conserving supersymmetry (SUSY) from the LHC searches motivate us to consider the new models in which the low-scale SUSY is still allowed. We propose a kind ofExpand


Hide and seek with natural supersymmetry at the LHC
A bstractGluinos that result in classic large missing transverse momentum signatures at the LHC have been excluded by 2011 searches if they are lighter than around 800 GeV. This adds to the tensionExpand
SUSY, the Third Generation and the LHC
A bstractWe develop a bottom-up approach to studying SUSY with light stops and sbottoms, but with other squarks and sleptons heavy and beyond reach of the LHC. We discuss the range of squark, gauginoExpand
(Light) stop signs
A bstractStop squarks with a mass just above the top’s and which decay to a nearly massless LSP are difficult to probe because of the large SM di-top background. Here we discuss search strategiesExpand
