Evolution of Plume Volcanism at Atla Regio, Venus
Journal of Geophysical Research: Planets, Volume 130, Issue 2, February 2025.Abstract Atla Regio is a large topographic rise, at the equator of Venus, considered to sit above a young mantle upwelling. Hosting several giant shield volcanoes, including Maat Mons, it is a strong candidate for recent eruptive activity. Through detailed analysis of material units and structures at Ozza, Maat and Sapas Mons, northern Dali Chasma and ...

Displaced lepton jet signatures from self-interacting dark matter bound states
Journal of High Energy Physics, 2019 We study self-interacting dark matter signatures at the Large Hadron Collider. A light dark photon, mediating dark matter self-interactions, can bind dark matter particles to form a bound state when they are produced via a heavy pseduoscalar in pp ...

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 ...

Strong CP problem, axions, and cosmological implications of CP violation
, 2017 In this talk, I present a pedagogical and historical review related to the CP symmetry. It includes the weak CP violation, the strong CP problem, "invisible" axions and cosmology, and Type-II leptogenesis.Comment: 21 pages of LaTeX file with 12 figures ...

Gravitino dark matter in brane-world cosmology [PDF]
, 2007 The gravitino dark matter hypothesis in the brane cosmology is studied. The theoretical framework is the CMSSM for particle physics and RS II brane model for gravity.

A multidisciplinary overview on the Tupi‐speaking people expansion
American Journal of Biological Anthropology, Volume 186, Issue 1, January 2025.Expansion of Tupi linguistic subfamilies. Abstract The cultural and biological diversity of South American indigenous groups represent extremes of human variability, exhibiting one of the highest linguistic diversities alongside a remarkably low within‐population genetic variation and an extremely high inter‐population genetic differentiation.

Journal of High Energy Physics, 2017 We discuss a novel signature of dark matter production at the LHC resulting from the emission of an additional Higgs boson in the dark sector. The presence of such a dark Higgs boson is motivated simultaneously by the need to generate the masses of the ...

Cosmological signatures of superheavy dark matter
Journal of High Energy Physics, 2020 We discuss two possible scenarios, namely the curvaton mechanism and the dark matter density modulation, where non-Gaussianity signals of superheavy dark matter produced by gravity can be enhanced and observed.

Landscape View at the Edge of a Mystery [PDF]
arXiv, 2015 The situation in particle physics after the discovery of the Higgs boson is discussed. Is the Standard Model consistent quantum field theory? Does it describe all experimental data? Are there any indications of physics beyond the SM? Is there another scale except for the EW and the Planck ones?

Origin of Mass - Horizons Expanding from the Nambu's Theory [PDF]
, 2016 Origin of mass may be strong dynamics of matter in the vacuum. Since the initial proposal of Nambu for the origin of the nucleon mass, the dynamical symmetry breaking in the strongly coupled underlying theories has been expanding the horizons in the context of the modern version of the origin of mass beyond the Standard Model (SM).
