1. Revisiting the SUSY μ problem and its solutions in the LHC era / Bae, Kyu Jung ; Baer, Howard ; Barger, Vernon ; Sengupta, Dibyashree
The supersymmetry (SUSY)-preserving μ parameter in SUSY theories is naively expected to be of order the Planck scale while phenomenology requires it to be of order the weak scale. [...]

2. LHC SUSY and WIMP dark matter searches confront the string theory landscape / Baer, Howard ; Barger, Vernon ; Salam, Shadman ; Serce, Hasan ; et al
The string theory landscape of vacua solutions provides physicists with some understanding as to the magnitude of the cosmological constant. [...]

3. Probing the Higgs Yukawa coupling to the top quark at the LHC via single top+Higgs production / Barger, Vernon ; Hagiwara, Kaoru ; Zheng, Ya-Juan
The conjoined production at the LHC of the single top and Higgs boson via t-channel weak boson exchange is ideal to probe the top-quark Yukawa coupling due to a delicate cancellation between the amplitudes with the htt and the hWW couplings. [...]

4. Gravity safe, electroweak natural axionic solution to strong CP and SUSY μ problems / Baer, Howard ; Barger, Vernon ; Sengupta, Dibyashree
Particle physics models with Peccei–Quinn (PQ) symmetry breaking as a consequence of supersymmetry (SUSY) breaking are attractive in that they solve the strong CP problem with a SUSY DFSZ-like axion, link the SUSY breaking and PQ breaking intermediate mass scales and can resolve the SUSY μ problem with a naturalness-required weak scale μ term whilst soft SUSY breaking terms inhabit the multi-TeV regime as required by LHC sparticle mass limits and the Higgs mass measurement.

5. Is natural higgsino-only dark matter excluded? / Baer, Howard ; Barger, Vernon ; Sengupta, Dibyashree ; Tata, Xerxes
The requirement of electroweak naturalness in supersymmetric (SUSY) models of particle physics necessitates light higgsinos not too far from the weak scale characterized by mweak∼mW,Z,h∼100GeV . [...]

6. LHC luminosity and energy upgrades confront natural supersymmetry models / Baer, Howard ; Barger, Vernon ; Gainer, James S. ; Sengupta, Dibyashree ; et al
The electroweak fine-tuning measure ΔEW allows for correlated supersymmetry (SUSY) soft terms as are expected in any ultraviolet complete theory. [...]

7. Anomaly-mediated SUSY breaking model retrofitted for naturalness / Baer, Howard ; Barger, Vernon ; Sengupta, Dibyashree
Anomaly-mediated supersymmetry breaking (AMSB) models seem to have become increasingly implausible due to 1) difficulty in generating a Higgs mass mh125 GeV, 2) typically unnatural superparticle spectra characterized by a large superpotential mu term, and 3) the possibility of a winolike lightest supersymmetry particle as dark matter now seems to be excluded.

8. Higgs and superparticle mass predictions from the landscape / Baer, Howard ; Barger, Vernon ; Serce, Hasan ; Sinha, Kuver
Predictions for the scale of SUSY breaking from the string landscape go back at least a decade to the work of Denef and Douglas on the statistics of flux vacua. [...]

9. Aspects of the same-sign diboson signature from wino pair production with light higgsinos at the high luminosity LHC / Baer, Howard ; Barger, Vernon ; Gainer, James S. ; Savoy, Michael ; et al
Naturalness arguments applied to simple supersymmetric (SUSY) theories require a set of light higgsinos with mass |μ| not too far from mh. [...]

10. What hadron collider is required to discover or falsify natural supersymmetry? / Baer, Howard ; Barger, Vernon ; Gainer, James S. ; Huang, Peisi ; et al
Weak scale supersymmetry (SUSY) remains a compelling extension of the Standard Model because it stabilizes the quantum corrections to the Higgs and W,Z boson masses. [...]
