On the gauge-invariance of SCET beyond leading power
Philipp Böer, Patrick Hager
We point out that the gauge-invariance of the subleading Lagrangian of soft-collinear effective theory is realised in an intricate way through momentum-conservation violating contr…
Soft-collinear gravity with fermionic matter
Martin Beneke, Patrick Hager, Dominik Schwienbacher
We extend the effective field theory for soft and collinear gravitons to interactions with fermionic matter fields. The full theory features a local Lorentz symmetry in addition to…
Soft-collinear gravity beyond the leading power
Martin Beneke, Patrick Hager, Robert Szafron
We construct "soft-collinear gravity", the effective field theory which describes the interaction of collinear and soft gravitons with matter (and themselves), to all orders in the…
Small-scale Cosmic Signatures of Feebly Interacting Massive Particles
Patrick Hager, Alexis Kassiteridis
Feebly Interacting Massive Particles (FIMPs), if they exist, should be notoriously difficult to detect even indirectly. In order to constrain them, we derive bounds for feeble theo…
