How generic is cosmic string formation in SUSY GUTs

, 2003
We study cosmic string formation within supersymmetric grand unified theories. We consider gauge groups having a rank between 4 and 8. We examine all possible spontaneous symmetry breaking patterns from the GUT down to the standard model gauge group ...

Solar Semidiurnal Variations in the Thermosphere and Ionosphere Forced From Above and From Below

Journal of Geophysical Research: Space Physics, Volume 130, Issue 1, January 2025.
Abstract The nature and origins of solar‐synchronous semidiurnal variations (SW2) in the thermosphere and ionosphere are explored through analysis of Thermosphere Ionosphere Electrodynamics General Circulation Model (TIEGCM) simulations that include and exclude forcing by tides at its 97‐km lower boundary derived from Ionospheric Connection (ICON ...

Loop-induced direct detection signatures from CP-violating scalar mediators

Journal of High Energy Physics, 2019
We investigate direct detection signatures of dark matter particles interacting with quarks via a light spin-0 mediator with general CP phases. Since tree-level scattering may be strongly suppressed in the non-relativistic limit, loop contributions play ...

A Mechanism of Ultraviolet Naturalness [PDF]

arXiv, 2015
The Standard Model (SM), as the quantum field theory of the strong and electroweak interactions, needs be carried into curved spacetime to incorporate gravity. This is done here not for the full but for the effective SM action by integrating-in affine curvature.

Can Dark Matter be an artifact of extended theories of gravity?

, 2016
In this article, we propose different background models of extended theories of gravity, which are minimally coupled to the SM fields, to explain the possibility of genesis of dark matter without affecting the SM particle sector.

Clouds and Ammonia in the Atmospheres of Jupiter and Saturn Determined From a Band‐Depth Analysis of VLT/MUSE Observations

Journal of Geophysical Research: Planets, Volume 130, Issue 1, January 2025.
Abstract The visible spectrum of Jupiter contains absorption bands of methane (619 nm) and ammonia (647 nm) that can be used to probe the cloud‐top pressures and ammonia abundance in Jupiter's atmosphere. Recently, it has been shown that filter‐averaged observations of Jupiter made with telescopes and filters accessible to backyard astronomers can be ...

Primordial Neutrinos: Hot in SM-GR-$\Lambda$-CDM, Cold in SM-LGT

, 2018
We replace general relativity (GR) and the cosmological constant ($\Lambda$) in the standard cosmology (SM-GR-$\Lambda$-CDM) with a Lorentz gauge theory of gravity (LGT) and show that the standard model (SM) neutrinos can be the cold dark matter (CDM ...

A transdisciplinary co‐conceptualisation of marine identity

People and Nature, Volume 6, Issue 6, Page 2300-2324, December 2024.
Abstract Challenge 10 of the United Nations Decade of Ocean Science for Sustainable Development (2021–2030) calls for the restoration of society's relationship with the ocean. Research suggests that the relationship people have with marine environments can influence their depth of engagement in marine citizenship action, and the important role for ...

Freeze-in, glaciation, and UV sensitivity from light mediators

Journal of High Energy Physics, 2022
Dark matter (DM) freeze-in through a light mediator is an appealing model with excellent detection prospects at current and future experiments. Light mediator freeze-in is UV-insensitive insofar as most DM is produced at late times, and thus the DM ...

Naturalizing Gravity of the Quantum Fields, and the Hierarchy Problem [PDF]

arXiv, 2017
It is shown that gravity can be incorporated into the Standard Model (SM) in a way solving the hierarchy problem. For this, the SM effective action in flat spacetime is adapted to curved spacetime via not only the general covariance but also the gauge invariance.
