Probing the Phenomenology of Dark Matter from Decoupled Freeze-Out
Geneviève Bélanger, Aoife Bharucha, Sreemanti Chakraborti +2
We consider a model of dark matter where the mediator corresponds to a superposition of a scalar and pseudoscalar, and the scenario where, after reheating, the number densities of…
Rekindling s-Wave Dark Matter Annihilation Below 10GeV with Breit-Wigner Effects
Geneviève Bélanger, Sreemanti Chakraborti, Cédric Delaunay +1
Velocity-independent (s-wave) annihilation of thermal Dark Matter is ruled out by CMB data for masses below 10GeV, effectively ruling out the possibility of indirectly detecting it…
Axion Bounds from Quantum Technology
Martin Bauer, Sreemanti Chakraborti, Guillaume Rostagni
A consistent treatment of the quantum field theory of an axion-like particle (ALP) interacting with Standard Model fields requires to account for renormalisation group running and…
On the Validity of Bounds on Light Axions for GeV
Martin Bauer, Sreemanti Chakraborti
Light bosonic dark matter fields that can be treated like a classical wave have non-linear field values close to massive bodies. Here we make the important observation that the qua…
GeV-scale dark matter with -wave Breit-Wigner enhanced annihilation
Genevieve Bélanger, Sreemanti Chakraborti, Yoann Génolini +1
We consider a light scalar dark matter candidate with mass in the GeV range whose -wave annihilation is enhanced through a Breit-Wigner resonance. The annihilation actually proc…
A Global Analysis of Resonance-enhanced Light Scalar Dark Matter
Tobias Binder, Sreemanti Chakraborti, Shigeki Matsumoto +1
We study a minimal model for a light scalar dark matter, requiring a light scalar mediator to address the core-cusp problem and interact with the standard model particles. We analy…
