Bound states of WIMP dark matter in Higgs-portal models. Part I. Cross-sections and transition rates

Journal of High Energy Physics, 2021
We investigate the role of the Higgs doublet in the thermal decoupling of multi-TeV dark matter coupled to the Weak interactions of the Standard Model and the Higgs. The Higgs doublet can mediate a long-range force that affects the annihilation processes

Estimating past fluid pH and evaporative conditions in Gale crater using terrestrial analog samples from Death Valley, CA

Meteoritics &Planetary Science, Volume 61, Issue 10, Page 2531-2548, October 2026.
Abstract Boron and lithium have been observed in Ca‐sulfate veins of Gale crater. These elements are highly water mobile and can inform us regarding the aqueous processes that may have taken place in Gale crater. However, the analysis of B in Gale crater is limited to low‐Fe rocks and minerals due to spectral interference of Fe with B in ChemCam data ...

Electroweak baryogenesis with vector-like leptons and scalar singlets

Journal of High Energy Physics, 2019
We investigate the viability of electroweak baryogenesis in a model with a first order electroweak phase transition induced by the addition of two gauge singlet scalars.

Direct detection and complementary constraints for sub-GeV dark matter

Journal of High Energy Physics, 2020
Traditional direct searches for dark matter, looking for nuclear recoils in deep underground detectors, are challenged by an almost complete loss of sensitivity for light dark matter particles. Consequently, there is a significant effort in the community

Chemical-potential-assisted particle production in FRW spacetimes

Journal of High Energy Physics, 2021
We analyze gravitational particle production assisted by chemical potential. By utilizing the uniformly smoothed Stokes-line method and Borel summation, we gain insight into the fine-grained history of enhanced particle production. Analytic/semi-analytic

Contextualising Mental Privacy in South Africa: Legal, Ethical, and Socio‐Cultural Considerations With Policy Recommendations

Developing World Bioethics, Volume 26, Issue 3, Page 212-226, September 2026.
ABSTRACT Mental privacy is a growing concern as neurotechnologies and digital mental health tools collect and process sensitive brain‐related data. In South Africa, cultural and religious diversity adds complexity to protecting mental privacy, with traditional healing practices, communal decision‐making, and spiritual beliefs influencing mental health ...

Probing small-scale power spectra with pulsar timing arrays

Journal of High Energy Physics, 2021
Models of Dark Matter (DM) can leave unique imprints on the Universe’s small scale structure by boosting density perturbations on small scales. We study the capability of Pulsar Timing Arrays to search for, and constrain, subhalos from such models.

Bolide light curve systematics from 75 recovered meteorites

Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2351-2392, September 2026.
Abstract How does the energy deposition profile (light curve), deceleration, and penetration depth in Earth's atmosphere depend on asteroid composition and meteorite type? Here, we present the light curve and velocity profile of 75 bolides from camera‐documented meteorite falls.

Electroweak phase transition with an SU(2) dark sector

Journal of High Energy Physics, 2021
We consider a non-Abelian dark SU(2)D model where the dark sector couples to the Standard Model (SM) through a Higgs portal. We investigate two different scenarios of the dark sector scalars with Z 2 symmetry, with Higgs portal interactions that can ...

Spiritual ecologies in transition: Bonbibi and the reconfiguration of people–nature relations in the Bangladeshi Sundarbans

People and Nature, Volume 8, Issue 8, Page 2866-2880, August 2026.
Abstract Local religious traditions serve as informal environmental institutions, characterized by socially embedded norms that guide behaviour without formal enforcement and influence human–environment interactions. This study investigates the role of Bonbibi worship as a system of moral regulation in the Bangladeshi Sundarbans and examines the ...
