Some Aspects of Inflationary Particle Production
… in the context of hybrid inflation and the grand unified theories Pati-Salam and SO(10). It is shown that a baryon asymmetry in accordance with observation may result. Moreover, we consider issues of quantum theory in curved space. Scalar fields in the expanding Universe and in Rindler space …

E6 inspired supersymmetric models
… group. The models are non-minimal supersymmetric theories which keep the Higgs mass stable against the quantum corrections from higher energy physics, but do not contain the mu-problem or little hierarchy problem of the Minimal Supersymmetric Standard Model (MSSM). Also, unlike conventional Grand …

Beyond the Standard Model: New scalars and new leptons
… related to those in the lepton sector in many grand unified theories. Comparing flavor-changing B decays with rare {dollar}\tau{dollar} decays, we find that rare B decays provide the strongest bounds and the most promising decay models are {dollar}B \to K\mu\tau{dollar} and …
