Unification and Local Baryon Number

, 2017
We investigate the possibility to find an ultraviolet completion of the simple extensions of the Standard Model where baryon number is a local symmetry.

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 ...

Thinking with Amazonian Indigenous Peoples to expand ideas on domestication

People and Nature, Volume 7, Issue 3, Page 560-574, March 2025.
Abstract Indigenous knowledges are being increasingly recognized as fundamental for environmental governance, ecosystem management and biodiversity conservation. However, they tend to be recognized by Western science only when they converge with Western scientific knowledge, while ontological differences are generally treated as irrelevant or ...

Visible GeV ALP from TeV Vector‐Like Leptons

Fortschritte der Physik, Volume 73, Issue 3, March 2025.
Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

Minimal Coupling and Attractors

, 2014
The effects of minimally coupling a gravity to matter on a flat Robertson-Walker geometry are explored. Particular attention is paid to the evolution of the symplectic structure and the Liouville measure it defines.

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 ...

Decolonizing English in Higher Education: Global Englishes and TESOL as Opportunities or Barriers

TESOL Quarterly, Volume 59, Issue 1, Page 281-309, March 2025.
Abstract English is core to HE (higher education) globally, with both HE and English seen as pathways to success for students. Yet, access to English is unequal and colonial ideologies associate English with Anglophone settings. Much of the research on English in HE has focused on elite institutions and students, while the majority of the world's HE ...

Comparison of the Distribution of the In Situ Ring Current Density Based on Magnetic Field Observations From THEMIS, MMS and Cluster

Journal of Geophysical Research: Space Physics, Volume 130, Issue 3, March 2025.
Abstract We review and extend previous work on the ring current density distribution by applying the curlometer technique to multi‐spacecraft magnetic field data on different spatial scales, directly comparing the results of three space missions: Time History of Events and Macroscale Interactions during Substorms (THEMIS), The Magnetospheric Multiscale

Reheating neutron stars with the annihilation of self-interacting dark matter

Journal of High Energy Physics, 2018
Compact stellar objects such as neutron stars (NS) are ideal places for capturing dark matter (DM) particles. We study the effect of self-interacting DM (SIDM) captured by nearby NS that can reheat it to an appreciated surface temperature through ...

Strong dark matter self-interaction from a stable scalar mediator

Journal of High Energy Physics, 2020
In face of the small-scale structure problems of the collisionless cold dark matter (DM) paradigm, a popular remedy is to introduce a strong DM self-interaction which can be generated nonperturbatively by a MeV-scale light mediator.
