Conformal vector dark matter and strongly first-order electroweak phase transition
Journal of High Energy Physics, 2019 We study a conformal version of the Standard Model (SM), which apart from SM sector, containing a U D (1) dark sector with a vector dark matter candidate and a scalar field (scalon).

Cosmological particle production and pairwise hotspots on the CMB
Journal of High Energy Physics, 2021 Heavy particles with masses much bigger than the inflationary Hubble scale H *, can get non-adiabatically pair produced during inflation through their couplings to the inflaton. If such couplings give rise to time-dependent masses for the heavy particles,

EX MACHINA: Emotional Break‐Ups and Digital Breakdown with AI Companions
Cultural Anthropology, Volume 41, Issue 3, Page 595-620, August 2026.ABSTRACT This essay examines romantic relationships between humans and AI companions, focusing on how technological breakdowns are experienced as emotional crises. Drawing on digital ethnography and interviews, it explores how users interpret their AI's malfunctions—such as hallucinations, memory loss, or sudden shutdowns—through metaphors of illness ...

Modulated reheating and large non-gaussianity in string cosmology [PDF]
, 2012 A generic feature of the known string inflationary models is that the same physics that makes the inflaton lighter than the Hubble scale during inflation often also makes other scalars this light.

A feeble window on leptophilic dark matter
Journal of High Energy Physics, 2019 In this paper we study a leptophilic dark matter scenario involving feeble dark matter coupling to the Standard Model (SM) and compressed dark matter-mediator mass spectrum.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.Abstract The data from a cosmic ray (CR) detector in Mexico City were collected over a period of 2 years from September 2023 to September 2025, during the maximum phase of Solar Cycle 25. The CR detector consists of an array of scintillators and measures the muonic component of secondary CRs.

Beyond the low energy approximation in braneworld cosmology [PDF]
, 2005 We develop a four-dimensional effective theory for Randall-Sundrum models which allows us to calculate long-wavelength adiabatic perturbations in a regime where the ρ 2 terms characteristic of braneworld cosmology are significant. This extends previous

Geophysical investigation of the Santa Marta impact structure—Piauí State, Brazil
Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1399-1416, July 2026.Abstract The Santa Marta impact structure in northeastern Brazil, recognized as a partially preserved complex crater, was investigated through an integrated geophysical study employing magnetotelluric (MT) and gravity methods. Our research provides constraints on the crater's subsurface architecture.

A simultaneous study of dark matter and phase transition: two-scalar scenario
Journal of High Energy Physics, 2019 The simplest extension of the Standard Model by only one real singlet scalar can explain the observed dark matter relic density while giving simultaneously a strongly first-order electroweak phase transition in the early universe. However, after imposing
