Electroweak precision tests of the SM and MSSM as well as Searches for Super-symmetric Particles and Higgs bosons at LEP II and their significance within the MSSM are discussed.

Electroweak precision tests of the SM and MSSM as well as Searches for Super-symmetric Particles and Higgs bosons at LEP II and their significance within the MSSM are discussed.

These final results from DELPHI searches for the Standard Model SM Higgs boson, together with benchmark scans of the Minimal Supersymmetric Standard Model MSSM neutral Higgs bosons, used data taken at centre-of-mass energies between 200 and 209 GeV with a total integrated luminosity of 224 pb−1.The data from 192 to 202 GeV are reanalyzed with improved b-tagging for MSSM final states decaying to...

SOFTSUSY is a program which accurately calculates the spectrum of super-particles in the Minimal Supersymmetric Standard Model (MSSM). The program solves the renormalisation group equations with theoretical constraints on soft supersymmetry breaking terms provided by the user. Weak-scale gauge coupling and fermion mass data (including one-loop finite MSSM corrections) are used as a boundary con...

ln the minimal supersymmetric model (MSSM), the tree level -mass of the lightest Higgs scalar h cannot be larger than the mass of the Z boson. We have computed the one-loop radiative correction to the upper bound on m„o as a function of the free parameters of the MSSM. We find that the dominant correction to m„o —mz is large and positive and grows like mi, where m& is the top-quark mass. As a r...

We investigate supersymmetric hybrid inflation in a realistic model based on the gauge symmetry $SU(4)_c \times SU(2)_L SU(2)_R$. The minimal standard (MSSM) $\mu$ term arises, following Dvali, Lazarides, and Shafi, from coupling of MSSM electroweak doublets to singlet superfield which plays an essential role inflation. primordial monopoles are inflated away by arranging that SU(2)_R$ is broken...

In the minimal supersymmetric standard model (MSSM) extended by a singlet superfield, when coupling between sector and MSSM is tiny, can be quasi dark with supersymmetry (SUSY). We investigate cosmological phenomena in this scenario obtain following observations: (i) parameter space solving small scale anomalies via self-interacting singlino matter (SIDM), first-order phase transition (FOPT) re...

These lectures give a general introduction to supersymmetry, emphasizing its application to models of elementary particle physics at the 100 GeV energy scale. I discuss the following topics: the construction of supersymmetric Lagrangians with scalars, fermions, and gauge bosons, the structure and mass spectrum of the Minimal Supersymmetric Standard Model (MSSM), the measurement of the parameter...
