Non-thermal production of pNGB dark matter and inflation
Journal of High Energy Physics, 2021 A pseudo Nambu-Goldstone boson (pNGB) is a natural candidate of dark matter in that it avoids the severe direct detection bounds. We show in this paper that the pNGB has another different and interesting face with a higher symmetry breaking scale.

Geo: Geography and Environment, Volume 12, Issue 2, July‐December 2025.Short Abstract Central and Eastern European geography, shaped by its historical hybridity and deep entanglement of natural and social sciences, offers a distinctive lens for rethinking disciplinary unity. By examining the current post‐transitional state of the field and four major thematic arenas, ranging from migration and the green transition to ...

Non-perturbative reheating and Nnaturalness
Journal of High Energy Physics, 2017 We study models in which reheating happens only through non-perturbative processes. The energy transferred can be exponentially suppressed unless the inflaton is coupled to a particle with a parametrically small mass. Additionally, in some models a light

Journal of High Energy Physics, 2020 We introduce leak-in dark matter, a novel out-of-equilibrium origin for the dark matter (DM) in the universe. We provide a comprehensive and unified discussion of a minimal, internally-thermalized, hidden sector populated from an out-of-equilibrium ...

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.Abstract The geology of a potential Artemis landing site on Mons Malapert is examined using remote sensing techniques and lessons learned from Apollo missions to the lunar surface. Orthomosaics, digital terrain models, illumination models, thermal conditions, crater size‐frequency distribution analyses, geomorphological mapping, spectral and ...

Generalized blind spots for dark matter direct detection in the 2HDM
Journal of High Energy Physics, 2020 In this paper we study the presence of generalized blind spots, i.e. regions of the parameter space where the spin-independent cross section for dark matter direct detection is suppressed, in the context of a generic 2HDM and a minimal fermionic Higgs ...

Quintessence Saves Higgs Instability
, 2018 We study a model where quintessence potential $e^{-\xi\phi}$ coupled to Higgs potential. We calculate the evolution of the quintessence, and track the running of the effective Higgs self-coupling.

Global Structure of the Cislunar Magnetotail and Its Evolution During Substorms
Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.Abstract So far, the structure and dynamics of the terrestrial magnetotail have largely been investigated within 31RE $31{R}_{E}$ (RE ${R}_{E}$ is the Earth's radius) because of the lack of in‐situ observations beyond that distance, as well as limitations of earlier empirical models.

Journal of High Energy Physics, 2019 Conventional approaches to probing axions and axion-like particles (ALPs) typically rely on a coupling to photons. However, if this coupling is extremely weak, ALPs become invisible and are effectively decoupled from the Standard Model. Here we show that

Current status and muon g − 2 explanation of lepton portal dark matter
Journal of High Energy Physics, 2020 In this paper, we summarize phenomenology in lepton portal dark matter (DM) models, where DM couples to leptons and extra leptons/sleptons. There are several possible setups: a DM field is either a complex/real scalar or a Dirac/Majorana fermion, and ...
