Remarks on Higgs Inflation
Remarks Higgs Inflation
2010/12/21
We discuss models where the Higgs boson of the electroweak standard model plays the role of the inflaton. We focus on the question of the violation of perturbative unitarity due to the coupling of the...
Warm DBI Inflation
Warm DBI Inflation
2010/12/21
We propose a warm inflationary model in the context of relativistic D-brane inflation in a warped throat. The inflaton has Dirac-Born-Infeld (DBI) kinetic term and is coupled to radiation through a di...
Mutated hybrid inflation in $f(R,{\Box}R)$-gravity
Mutated hybrid inflation $f(R,{\Box}R)$-gravity
2010/12/21
A new hybrid inflationary scenario in the context of f(R,R)-gravity is proposed. Demanding
the waterfall field to ‘support the potential from below’ [unlike the original proposal by Stewart in Phys....
Galilean symmetry in the effective theory of inflation: new shapes of non-Gaussianity
Galilean symmetry effective theory of inflation shapes of non-Gaussianity
2010/12/21
We study the consequences of imposing an approximate Galilean symmetry on the Effective Theory
of Inflation, the theory of small perturbations around the inflationary background. This approach allows...
Inflation of Bianchi type-$\Rmnum{7}_0$ Universe with Dirac Field in Einstein-Cartan theory
Einstein-Cartan theory Bianchi type-V II0 inflation Dirac field
2010/12/21
We discuss the Bianchi type-V II0 cosmology with Dirac field in Einstein-Cartan the-ory. We obtain the equations of Dirac field and gravitational field in Einstein-Cartan theory. We find a Bianchi typ...
The discovery of many novel realizations of the in ationary universe paradigm has led to a degeneracy problem: many di erent in ationary Lagrangians generate the same perturbation spectra.
We find the natural embedding of the (R + R2)-inflationary model into the recently constructed
F(R) supergravity. It gives a simple and viable realization of chaotic inflation in supergravity. The on...
