Argon as the test of two interpretations of the LZ 248 keV recoil
Howard Baer, Vernon Barger
Argon decides what the LZ 248 keV recoil is. Read as an excited pseudo-Dirac state dropping to its ground state, the event predicts a nuclear-recoil line in argon at |δ|\,m_χ/(m_χ+…
Exothermic dark matter and the 248 keV nuclear recoil in LUX-ZEPLIN
Howard Baer, Vernon Barger
The single 248-keV nuclear-recoil candidate reported by LZ is reproduced by dark matter that downscatters, with the relic in the excited state of a pseudo-Dirac pair and a splittin…
Cosmological moduli problem ameliorated by decaying WIMPs
Howard Baer, Vernon Barger, Robert Wiley Deal
We investigate the cosmological moduli problem (CMP) in the context of supersymmetric models where discrete R-symmetries are used to suppress the mu term, and where mu is regenerat…
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…
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 term must be forbidden, then regenerated at the weak scale, 2. it allows for -parity violating…
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-t…
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…
Aspects of the WIMP quality problem and R-parity violation in natural supersymmetry with all axion dark matter
Howard Baer, Vernon Barger, Jessica Bolich +2
In supersymmetric models where the mu problem is solved via discrete R-symmetries, then both the global U(1)_{PQ} (Peccei-Quinn, needed to solve the strong CP problem) and R-parity…
All axion dark matter from supersymmetric models
Howard Baer, Vernon Barger, Dibyashree Sengupta +1
Supersymmetric models accompanied by certain anomaly-free discrete R-symmetries Z_n^R are attractive in that 1. the R-symmetry (which can arise from compactified string theory as a…
Prospects for supersymmetry at high luminosity LHC
Howard Baer, Vernon Barger, Jessica Bolich +5
Weak scale supersymmetry (SUSY) is highly motivated in that it provides a 't Hooft technically natural solution to the gauge hierarchy problem. However, recent strong limits from s…
Implications of Higgs mass for hidden sector SUSY breaking
Howard Baer, Vernon Barger, Jessica Bolich +1
Hidden sector SUSY breaking where charged hidden sector fields obtain SUSY breaking vevs once seemed common in dynamical SUSY breaking (DSB). In such a case, scalars can obtain lar…
Living dangerously with decoupled first/second generation scalars: SUSY prospects at the LHC
Howard Baer, Vernon Barger, Kairui Zhang
The string landscape statistical draw to large scalar soft masses leads to a mixed quasi-degeneracy/decoupling solution to the SUSY flavor and CP problems where first/second genera…
Beyond the Standard Model: An overview
Howard Baer
At present, the Standard Model (SM) agrees with almost all collider data. Yet, three finetuning issues -- the Higgs mass problem, the strong CP problem and the cosmological constan…
The Hunt for New Physics at the Large Hadron Collider
P. Nath, B. D. Nelson, H. Davoudiasl +84
The Large Hadron Collider presents an unprecedented opportunity to probe the realm of new physics in the TeV region and shed light on some of the core unresolved issues of particle…
Physics Beyond the Standard Model
Howard Baer
I present a brief overview of some exciting possibilities for physics Beyond the Standard Model. I include short discussions of neutrino physics, the strong CP problem and axions,…
