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…
Monopole Problem and Extensions of Supersymmetric Hybrid Inflation
R. Jeannerot, S. Khalil, G. Lazarides
We discuss, in the context of a concrete supersymmetric grand unified model based on the Pati-Salam gauge group SU(4)_c x SU(2)_L x SU(2)_R, two "natural" extensions of supersymmet…
Supersymmetric Hybrid Inflation
G. Lazarides
The non-supersymmetric and supersymmetric versions of hybrid inflation are summarized. It is emphasized that supersymmetric hybrid inflation (with its extensions) is an extremely "…
Inflation, the mu Problem and Maximal nu_mu-nu_tau Mixing
G. Lazarides
A supersymmetric model based on a left-right symmetric gauge group, which `naturally' leads to hybrid inflation, is studied. It is shown that the mu problem can be easily solved in…
Inflation
G. Lazarides
The shortcomings of the Standard Big Bang Cosmological Model as well as their resolution in the context of inflationary cosmology are discussed. The inflationary scenario and the s…
