In this work, we classify all the effective $U(1)$ symmetries and their associated Noether charges in standard model (SM) its minimal supersymmetric extension (MSSM) from highest scale after inflation down to weak scale. We then demonstrate that discovery of violation baryon minus lepton number ($B\ensuremath{-}L$), which pinpoints primordial Universe at any cosmic temperature above 30 TeV, wil...

A fairly elementary introduction to supersymmetric field theories in general and the minimal supersymmetric Standard Model (MSSM) in particular is given. Topics covered include the cancellation of quadratic divergencies, the construction of the supersymmetric Lagrangian using superfields, the field content of the MSSM, electroweak symmetry breaking in the MSSM, mixing between different superpar...

The four LEP collaborations have searched for neutral Higgs bosons predicted within the MSSM. The experimental results included the searches for neutral Higgs bosons at LEP1 and LEP2 in final states as expected in the MSSM. The combined LEP data show no significant excess of events over the expectation from the Standard Model predictions. The search results are interpreted within the MSSM for a...

The minimal supersymmetric extension of the Standard Model (MSSM) is reviewed. In the most general framework with minimal field content and R-parity conservation, the MSSM is a 124-parameter model (henceforth called MSSM-124). An acceptable phenomenology occurs only at exceptional points (and small perturbations around these points) of MSSM-124 parameter space. Among the topics addressed in thi...

A global statistical χ2 analysis of all electroweak data including new data on the anomalous magnetic moment of the muon and the b → Xsγ decay rate in both the SM and the MSSM has been performed. The total χ2 of the MSSM is better than in the SM, mainly because of the W -mass and aμ, although the total probability is similar in both models due to the larger number of parameters in the MSSM. In ...

The corrections to the MSSM Higgs boson masses and couplings performed in this millennium are briefly reviewed. For the lightest MSSM Higgs boson mass, mh, we list the current status of the intrinsic uncertainties (due to unknown higher-order corrections) and the parametric uncertainties (due to the imperfect experimental knowledge of the input parameters). The need for high-precision calculati...

We investigate and compare additional CP-even, CP-odd charged scalar states appearing in two popular Beyond the Standard Model scenarios. focus on simplest possible Higgs sector within warped extra-dimensions supersymmetry, with aim to differentiate between them. In each case, we analyze couplings of new states, looking for distinguishing signatures. show that gauge bosons first Kaluza-Klein ex...
