We discuss the phenomenology of third generation sfermions paying particular attention to the implications of the Yukawa couplings and to the left-right mixing. Analytical formulae are given for the sfermion mixing, the production cross sections at e+e- colliders, and for all possible two body decay widths that can occur at tree level. In case of the light stop stop we give in addition the analytical formulae for the most important three body decay widths. We give detailed numerical discussion of the various production cross sections at LEP2 and a future e+e- Linear Collider. We discuss the various decay channels paying particular attention on the decays into Higgs and vector bosons, and on the three body decays of the light stop.
The ATLAS and CMS experiments have recently announced the discovery of a Higgs-like resonance with mass close to 125 GeV. Overall, the data is consistent with a Standard Model (SM)-like Higgs boson. Such a particle may arise in the minimal supersymme
Many proposed and upcoming experiments seek to observe signals from upward going air showers initiated by tau leptons resulting from neutrino interactions inside the Earth. To save calculation time, event estimations for these observation methods are
In a supersymmetric (SUSY) theory, the IR-contributions to the Higgs mass are calculable below the mediation scale $Lambda_{text{UV}}$ in terms of the IR field content and parameters. However, logarithmic sensitivity to physics at $Lambda_{text{UV}}$
The most naive interpretation of the BICEP2 data is the chaotic inflation by an inflaton with a quadratic potential. When combined with supersymmetry, we argue that the inflaton plays the role of right-handed scalar neutrino based on rather general c
In spite of rapid experimental progress, windows for light superparticles remain. One possibility is a ~100 GeV tau slepton whose t-channel exchange can give the correct thermal relic abundance for a relatively light neutralino. We pedagogically revi
