Heavy neutron stars from light scalars
Reuven Balkin, Javi Serra, Konstantin Springmann +2
We study how light scalar fields can change the stellar landscape by triggering a new phase of nuclear matter. Scalars coupled to nucleons can develop a non-trivial expectation val…
Towards an electrostatic storage ring for fundamental physics measurements
Chiara Brandenstein, Stefan Stelzl, Erwin Gutsmiedl +3
We describe a new table-top electrostatic storage ring concept for keV polarized ions at frozen spin condition. The device will ultimately be capable of measuring magnetic fie…
White dwarfs as a probe of exceptionally light QCD axions
Reuven Balkin, Javi Serra, Konstantin Springmann +2
We study the effects of exceptionally light QCD axions on the stellar configuration of white dwarfs. At finite baryon density, the non-derivative coupling of the axion to nucleons…
RG of GR from On-shell Amplitudes
Pietro Baratella, Dominik Haslehner, Maximilian Ruhdorfer +2
We study the renormalization group of generic effective field theories that include gravity. We follow the on-shell amplitude approach, which provides a simple and efficient method…
Electric dipole moments at one-loop in the dimension-6 SMEFT
Jonathan Kley, Tobias Theil, Elena Venturini +1
In this paper we present the complete expressions of the lepton and neutron electric dipole moments (EDMs) in the Standard Model Effective Field Theory (SMEFT), up to 1-loop and di…
Runaway Relaxion from Finite Density
Reuven Balkin, Javi Serra, Konstantin Springmann +2
Finite density effects can destabilize the metastable vacua in relaxion models. Focusing on stars as nucleation seeds, we derive the conditions that lead to the formation and runaw…
