Gravitino Thermal Production, Dark Matter, and Reheating of the Universe
Helmut Eberl, Ioannis D. Gialamas, Vassilis C. Spanos
We present a full one-loop calculation of the gravitino thermal production rate, beyond the so-called hard thermal loop approximation, using the corresponding thermal spectral func…
Generalized uncertainty principle and neutrino phenomenology
Ioannis D. Gialamas, Timo J. Kärkkäinen, Luca Marzola
Generalized uncertainty principles are effective changes to the Heisenberg uncertainty principle that emerge in several quantum gravity models. In the present letter, we study the…
Gravitational corrections to electroweak vacuum decay: metric vs. Palatini
Ioannis D. Gialamas, Alexandros Karam, Thomas D. Pappas
We consider the standard Einstein-Hilbert-Higgs action where the Higgs field couples nonminimally with gravity via the term , and investigate the stability of the…
Gravitino thermal production
Helmut Eberl, Ioannis D. Gialamas, Vassilis C. Spanos
In this talk we present a new calculation of the gravitino production rate, using its full one-loop corrected thermal self-energy, beyond the hard thermal loop approximation. Gravi…
Gravitino thermal production revisited
Helmut Eberl, Ioannis D. Gialamas, Vassilis C. Spanos
We calculate the gravitino production rate, computing its one-loop thermal self-energy. Gravitino production processes that do not result through thermal cuts of its self-energy, h…
