Gravity and axions from a random UV QFT

, 2014
It is postulated that the UV QFT is enormous and random. The coupling of the Standard Model to such QFT is analyzed. It is argued that massless 4d gravity and axions are general avatars of the postulate.

Monochromatic Gamma Rays from Dark Matter Annihilation to Leptons [PDF]

, 2015
We investigate the relation between the annihilation of dark matter (DM) particles into lepton pairs and into 2-body final states including one or two photons.

Dark Matter: A Primer [PDF]

, 2011
Dark matter is one of the greatest unsolved mysteries in cosmology at the present time. About 80% of the universe's gravitating matter is non-luminous, and its nature and distribution are for the most part unknown.

On Babushkas and Postcapitalism: Theorising Diverse Economies from the Global East

Antipode, EarlyView.
Abstract As transformative visions for more just and sustainable societies multiply around the globe, the Diverse and Community Economies approach presents one of the most influential strategies to advance postcapitalist visions. In this paper, we contribute to this project based on our research and activism in the Global East, intended here as Central

Particle Physics and Cosmology

, 2014
Today, both particle physics and cosmology are described by few parameter Standard Models, i.e. it is possible to deduce consequence of particle physics in cosmology and vice verse.

Non-Abelian Einstein-Born-Infeld-Dilaton Cosmology [PDF]

, 2005
The non-abelian Einstein-Born-Infeld-Dilaton theory, which rules the dynamics of tensor-scalar gravitation coupled to a $su(2)$-valued gauge field ruled by Born-Infeld lagrangian, is studied in a cosmological framework.

Thermal QCD Axions across Thresholds

Journal of High Energy Physics, 2021
Thermal axion production in the early universe goes through several mass thresholds, and the resulting rate may change dramatically across them. Focusing on the KSVZ and DFSZ frameworks for the invisible QCD axion, we perform a systematic analysis of ...

Oued Chebeika 002: A new CI1 meteorite linked to outer solar system bodies

Meteoritics &Planetary Science, EarlyView.
Abstract CI1 chondrites are rare meteorites with high scientific value. In fact, they are the most chemically primitive meteorites and show evidence of intense parent‐body aqueous alteration. They also share strong similarities with samples from Ryugu and Bennu asteroids returned by the JAXA Hayabusa2 and NASA's OSIRIS‐REx missions.

What are the Building Blocks of Our Universe? [PDF]

, 2004
We are told that we are living in a Golden Age of Astronomy. Cosmological Parameters are found with un precedented accuracy. Yet, the known form of matter forms only a small fraction of the total energy density of the universe.

Dark Matter from Minimal Flavor Violation

, 2011
We consider theories of flavored dark matter, in which the dark matter particle is part of a multiplet transforming nontrivially under the flavor group of the Standard Model in a manner consistent with the principle of Minimal Flavor Violation (MFV). MFV
