Semi-shifted hybrid inflation with B-L cosmic strings
George Lazarides, Iain N. R. Peddie, Achilleas Vamvasakis
We discuss a new inflationary scenario which is realized within the extended supersymmetric Pati-Salam model which yields an acceptable b-quark mass for universal boundary conditio…
Standard-smooth hybrid inflation
G. Lazarides, A. Vamvasakis
We consider the extended supersymmetric Pati-Salam model which, for mu>0 and universal boundary conditions, succeeds to yield experimentally acceptable b-quark masses by moderately…
Hybrid inflation followed by modular inflation
George Lazarides
Inflationary models with a superheavy scale F-term hybrid inflation followed by an intermediate scale modular inflation are considered. The restrictions on the power spectrum P_R o…
New smooth hybrid inflation
G. Lazarides, A. Vamvasakis
We consider the extension of the supersymmetric Pati-Salam model which solves the b-quark mass problem of supersymmetric grand unified models with exact Yukawa unification and univ…
Supersymmetric Dark Matter, Inflation and Yukawa Quasi-Unification
G. Lazarides, C. Pallis
The construction of supersymmetric grand unified models based on the Pati-Salam gauge group and leading to a set of Yukawa quasi-unification conditions is briefly reviewed. For eac…
Introduction to Inflationary Cosmology
George Lazarides
The early universe according to the big bang and the grand unified theories is discussed. The shortcomings of big bang are summarized together with their resolution by inflationary…
