This thesis contains three parts. The first concerns the conjecture that the weakness of gravitational interactions between elementary particles, when compared to electromagnetic interactions, is not accidental but a requirement for any theory where

We generalize dark matter production to a two-metric framework whereby the physical metric, which couples to the Standard Model (SM), is conformally and/or disformally related to the metric governing the gravitational dynamics. We show that this setu

We couple a sterile neutrino sector to a spin-3/2 particle and show that with a Planck reduced coupling, we can obtain a sufficiently long lifetime making the spin-3/2 particle a good dark matter candidate. We show that this dark matter candidate can

Physical Review

We perform a systematic analysis of dark matter production during post-inflationary reheating. Following the period of exponential expansion, the inflaton begins a period of damped oscillations as it decays. These oscillations and the evolution of te

SPINOR TWO-POINT FUNCTIONS AND PEIERLS BRACKET IN DE SITTER SPACE

Autor: Giampiero Esposito, Raju Roychowdhury

Publikováno v: International Journal of Geometric Methods in Modern Physics. :1069-1088

This paper studies spinor two-point functions for spin-1/2 and spin-3/2 fields in maximally symmetric spaces such as de Sitter spacetime, by using intrinsic geometric objects. The Feynman, positive- and negative-frequency Green functions are then obt

Gravitinos tunneling from traversable Lorentzian wormholes

Autor: Ali Övgün, İzzet Sakallı

Publikováno v: Astrophysics and Space Science. 359

Recent research shows that Hawking radiation (HR) is also possible around the trapping horizon of a wormhole. In this article, we show that the HR of gravitino (spin-$3/2$) particles from the traversable Lorentzian wormholes (TLWH) reveals a negative

Dynamical soft terms with unbroken supersymmetry

Autor: Gia Dvali, Gian F. Giudice, Savas Dimopoulos, Riccardo Rattazzi

Publikováno v: Nuclear Physics B. 510:12-38

We construct a class of simple and calculable theories for the supersymmetry breaking soft terms. They are based on quantum modified moduli spaces. These theories do not break supersymmetry in their ground state; instead we postulate that we live in
