After an introduction recalling the theoretical motivation for low energy (100 GeV to TeV scale) supersymmetry, this review describes the theory and experimental implications of the soft supersymmetry-breaking Lagrangian of the general minimal supersymmetric standard model (MSSM). Extensions to include neutrino masses and nonminimal theories are also discussed. Topics covered include models of supersymmetry breaking, phenomenological constraints from electroweak symmetry breaking, flavor/CP violation, collider searches, and cosmological constraints including dark matter and implications for baryogenesis and inflation.

In conventional supergravity theories, supersymmetry is broken by a non-zero F -term, and the cosmological constant is fine tuned to zero by a constant in the superpotential W . We discuss a class of supergravity theories with vanishing F -terms but W = 0 being generated dynamically. The cosmological constant is assumed to be cancelled by a non-zero D-term. In this scenario the gravity-mediated soft masses depend only on a single parameter, the gravitino mass. They are automatically universal, independently of the Kähler metric, and real. Thus, dangerous flavor or CP violating interactions are suppressed. Unlike in conventional supergravity models, the Polonyi problem does not arise.

“…It can solve the hierarchy problem, provides a Dark Matter candidate and leads to a unification of the gauge couplings, thus paving the way to a Grand Unified Theory. The most frequently studied realizations of SUSY are the Minimal Supersymmetric Standard Model (MSSM) [2][3][4][5] and the Next-toMinimal Supersymmetric Standard Model (NMSSM) [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. In contrast to the SM, in the MSSM two Higgs doublets are required.…”

Higgs-boson masses and mixing matrices in the NMSSM: analysis of on-shell calculations

et al. 2017

We analyze the Higgs-boson masses and mixing matrices in the NMSSM based on an on-shell (OS) renormalization of the gauge-boson and Higgs-boson masses and the parameters of the top/scalar top sector. We compare the implementation of the OS calculations in the codes NMSSM-CALC and NMSSM-FeynHiggs up to O(α t α s ). We identify the sources of discrepancies at the one-and at the twoloop level. Finally we compare the OS and DR evaluation as implemented in NMSSMCALC. The results are important ingredients for an estimate of the theoretical precision of Higgs-boson mass calculations in the NMSSM.
