Sommerfeld Effect and Bound State Formation for Dark Matter Models with Colored Mediators with SE+BSF4DM
Mathias Becker, Emanuele Copello, Julia Harz +1
In the universal framework of simplified -channel dark matter models, the calculation of the relic abundance can be dominated by mediator annihilation when the dark matter and m…
t-channel dark matter at the LHC -- a whitepaper
Chiara Arina, Benjamin Fuks, Luca Panizzi +67
This report, summarising work achieved in the context of the LHC Dark Matter Working Group, investigates the phenomenology of -channel dark matter models, spanning minimal setup…
Multiple Soft Scatterings in Scalar Dark Matter Freeze-In
Mathias Becker, Maria Jose Fernandez Lozano, Julia Harz +1
We present an improved calculation of the freeze-in production rate for scalar dark matter (DM) from a gauge-charged parent particle via a renormalizable interaction. Building on t…
ALP Production from Abelian Gauge Bosons: Beyond Hard Thermal Loops
Mathias Becker, Julia Harz, Enrico Morgante +2
Previous computations of feebly interacting particle production have encountered issues with unphysical (negative) interaction rates at soft momenta. We address this problem by stu…
