Chaotic inflation, radiative corrections and precision cosmology
V. Nefer Senoguz, Qaisar Shafi
We employ chaotic (phi^2 and phi^4) inflation to illustrate the important role radiative corrections can play during the inflationary phase. Yukawa interactions of phi, in particul…
Unparticle physics with broken scale invariance
Vernon Barger, Yu Gao, Wai-Yee Keung +2
If scale invariance is exact, unparticles are unlikely to be probed in colliders since there are stringent constraints from astrophysics and cosmology. However these constraints ar…
Inflation and Unification
Qaisar Shafi, V. Nefer Senoguz
Two distinct classes of realistic inflationary models consistent with present observations are reviewed. The first example relies on the Coleman-Weinberg potential and is readily r…
Non-thermal leptogenesis with strongly hierarchical right handed neutrinos
V. Nefer Senoguz
Assuming the Dirac-type neutrino masses m_D are related to quark or charged lepton masses, neutrino oscillation data indicate that right handed neutrino masses are in general stron…
Supersymmetric And Smooth Hybrid Inflation In The Light Of WMAP3
Mansoor ur Rehman, V. N. Senoguz, Qaisar Shafi
In their minimal form both supersymmetric and smooth hybrid inflation yield a scalar spectral index n_s close to 0.98, to be contrasted with the result n_s=0.951+0.015-0.019 from W…
Non-Canonical MSSM, Unification, And New Particles At The LHC
Ilia Gogoladze, Tianjun Li, V. N. Senoguz +1
We consider non-canonical embeddings of the MSSM in high-dimensional orbifold GUTs based on the gauge symmetry SU(N), N=5,6,7,8. The hypercharge normalization factor k_Y can either…
