Charged Planckian Interacting Dark Matter
Mathias Garny, Andrea Palessandro, McCullen Sandora +1
A minimal model of Cold Dark Matter (CDM) is a very massive particle with only gravitational interactions, also called Planckian Interacting Dark Matter (PIDM). Here we consider an…
Leading-logarithmic threshold resummation of the Drell-Yan process at next-to-leading power
Martin Beneke, Alessandro Broggio, Mathias Garny +4
We resum the leading logarithms , near the kinematic threshold of the Drell-Yan process at next-to-leading power in the…
Interplay of super-WIMP and freeze-in production of dark matter
Mathias Garny, Jan Heisig
Non-thermalized dark matter is a cosmologically valid alternative to the paradigm of weakly interacting massive particles. For dark matter belonging to a -odd sector that cont…
Anomalous dimension of subleading-power -jet operators II
Martin Beneke, Mathias Garny, Robert Szafron +1
We continue the investigation of the anomalous dimension of subleading-power -jet operators. In this paper, we focus on the operators with fermion number one in each collinear d…
Lyman- forest constraints on interacting dark sectors
Mathias Garny, Thomas Konstandin, Laura Sagunski +1
The Lyman- forest is a valuable probe of dark matter models featuring a scale-dependent suppression of the power spectrum as compared to CDM. In this work, we present a new e…
Top-philic dark matter within and beyond the WIMP paradigm
Mathias Garny, Jan Heisig, Marco Hufnagel +1
We present a comprehensive analysis of top-philic Majorana dark matter that interacts via a colored t-channel mediator. Despite the simplicity of the model -- introducing three par…
