Adiabatic response in the Migdal Effect
Stefan Nellen Mondragón, Josef Pradler, Mukul Sholapurkar
The Migdal effect-the prompt ionization induced by a sudden nuclear recoil-is widely used in direct dark matter searches, yet its validity beyond the impulse approximation has rema…
Towards a theory of dissipative Dark Matter I: the Born limit
Garance Lankester--Broche, Josef Pradler
We derive the energy-differential cross section and energy loss rate for dissipative self-interacting dark matter (dSIDM) models within the Born regime using perturbative quantum f…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
Underground Production of Electromagnetic Dark States by MeV-scale Electron Beams and Detection with CCDs
Helmut Eberl, Maximilian Fahrecker, Josef Pradler
In this work we explore the possibility of new light fermionic particles with millicharge or electromagnetic form factor interactions and their underground production via an electr…
On the existence of bound states in SIMP dark sectors
Xiaoyong Chu, Josef Pradler, Daris Samart
In strongly interacting massive particle (SIMP) scenarios, dark matter is comprised of stable dark pions whose or reactions set the dark matter relic abundance. R…
Physics Briefing Book: Input for the 2026 update of the European Strategy for Particle Physics
Jorge de Blas, Monica Dunford, Emanuele Bagnaschi +127
The European Strategy for Particle Physics (ESPP) reflects the vision and presents concrete plans of the European particle physics community for advancing human knowledge in fundam…
