Serendipitous supersymmetric solution to the strong CP problem
Howard Baer, Vernon Barger, Dibyashree Sengupta
The Minimal Supersymmetric Standard Model (MSSM) has several problems: 1. its mu term must be forbidden, then regenerated at the weak scale, 2. it allows for R-parity violating sup…
Can blind spots save neutralino dark matter in natural supersymmetry models?
Howard Baer, Vernon Barger, Dibyashree Sengupta
Natural supersymmetry (SUSY) models remain viable even in the face of LHC Run 2 sparticle search limits. However, the LZ experiment has placed strong limits on light higgsino dark…
Natural SUSY with mixed axion/axino dark matter
Howard Baer, Vernon Barger, Kairui Zhang
While supersymmetric models provide a solution to the big hierarchy problem, natural SUSY is also allowed by the little hierarchy problem. In supersymmetric models which include th…
pMSSM versus complete models and the excellent prospects for top-squark discovery at HL-LHC
Howard Baer, Vernon Barger, Kairui Zhang
LHC sparticle search limits are usually performed within the context of simplified models and subsequently interpreted within the 19 parameter phenomenological MSSM (pMSSM) as to h…
Natural supersymmetry at a muon collider
Howard Baer, Vernon Barger, Jessica Bolich +2
There is great interest within the particle physics community for building a collider with center-of-mass (CoM) energies ranging from 1-14 TeV. For Beyond…
Reach of e^+e^- Higgs factory for light higgsinos via electroweak precision observables and comparison with other future facilities
Howard Baer, Vernon Barger, Natsumi Nagata +1
Light higgsinos with mass ~100-400 GeV are well-motivated from naturalness considerations within supersymmetric models. However, at hadron colliders such as CERN LHC, they are rath…
