26. Constraining Flavored Dark Matter: A Systematic Study in the DMFV Framework

Lena Rathmann (RWTH Aachen University)

6/2/25, 5:00 PM

DM Models and Theory

Contributed Talk

The null results of dark matter searches targeting weakly interacting massive particles (WIMPs) put increasing pressure on the simplest realizations of WIMP models. In response, we explore an extended dark sector with a non-trivial flavor structure within the Dark Minimal Flavor Violation (DMFV) framework. These models extend the standard dark matter paradigm by introducing flavor-dependent...

46. Unlocking the Inelastic Dark Matter Window with Vector Mediators

Ana Luisa Foguel (University of São Paulo)

6/2/25, 5:20 PM

DM Models and Theory

Contributed Talk

Despite the robust cosmological and astrophysical evidence confirming the existence of a non-baryonic matter component in the Universe, the underlying nature of Dark Matter (DM) remains a mystery. Among the several possible scenarios, light DM candidates thermally produced in the early Universe are especially interesting, since their abundance could be set via the standard freeze-out...

67. Resonant or asymmetric: The status of sub-GeV dark matter

Taylor Gray (Chalmers University of Technology)

6/2/25, 5:40 PM

DM Models and Theory

Contributed Talk

Sub-GeV dark matter (DM) has been gaining significant interest in recent years, since it can account for the thermal relic abundance while evading nuclear recoil direct detection constraints. However, sub-GeV DM is still subject to a number of constraints from laboratory experiments, and from astrophysical and cosmological observations. In this work, we compare these observations with the...

47. Dark matter as bound states in asymptotically safe quantum gravity.

Abhishek Chikkaballi (National Centre for Nuclear Research, Warsaw)

DM Models and Theory

Contributed Talk

Many dark matter models become unviable when embedded into the framework of asymptotically safe quantum gravity. In this work, we investigate dark matter arising as bound states of fundamental fermions in the strongly-coupled regime of a gauge theory. Modeling the self-interactions of dark baryons via the effective-range approach, we perform a multi-scale analysis in which we combine...

39. Listening for ultra-heavy dark matter with underwater acoustic detectors

Damon Cleaver (damon.cleaver@kcl.ac.uk)

6/2/25, 6:20 PM

DM Direct Detection

Poster + Lightning Talk

Ultra-heavy dark matter is a class of candidates for which direct detection experiments are ineffective due to the suppressed dark matter flux. We explore the potential of large underwater acoustic arrays, developed for ultra-high energy neutrino detection, to detect ultra-heavy dark matter. As ultra-heavy dark matter traverses seawater, it deposits energy through nuclear scattering,...

62. Interactions of boosted dark matter with nuclei and implications for DUNE

Helena Kolesova (University of Stavanger)

6/2/25, 6:25 PM

DM Direct Detection

Poster + Lightning Talk

Halo dark matter particles with sub-GeV masses do not have sufficient kinetic energy to induce detectable recoils of heavy nuclei in the detectors, direct detection experiments, hence, loose sensitivity to such light dark matter. Dark matter particles can be, however, accelerated by different mechanisms and even light dark matter can then provide observable signatures. These signatures include...
