Many models of physics beyond the Standard Model predict minicharged particles to which current and near future low-energy experiments are highly sensitive. Such minicharges arise generically from kinetic mixing in theories containing at least two U(...

Particle interpretation of the PVLAS data: Neutral versus charged particles (2007)
Journal Article
Ahlers, M., Gies, H., Jaeckel, J., & Ringwald, A. (2007). Particle interpretation of the PVLAS data: Neutral versus charged particles. Physical Review D, Particles and fields, 75, https://doi.org/10.1103/physrevd.75.035011

Recently the PVLAS Collaboration reported the observation of a rotation of linearly polarized laser light induced by a transverse magnetic field—a signal being unexpected within standard QED. Two mechanisms have been proposed to explain this result:... Read More about Particle interpretation of the PVLAS data: Neutral versus charged particles.

SUSY breaking by a metastable ground state: Why the early universe preferred the non-supersymmetric vacuum (2007)
Journal Article
Abel, S. A., Chu, C., Jaeckel, J., & Khoze, V. V. (2007). SUSY breaking by a metastable ground state: Why the early universe preferred the non-supersymmetric vacuum. Journal of High Energy Physics, 2007(01), https://doi.org/10.1088/1126-6708/2007/01/089

Supersymmetry breaking in a metastable vacuum is re-examined in a cosmological context. It is shown that thermal effects generically drive the Universe to the metastable minimum even if it begins in the supersymmetry-preserving one. This is a generic...

Polarized light propagating in a magnetic field as a probe of millicharged fermions (2006)
Journal Article
Gies, H., Jaeckel, J., & Ringwald, A. (2006). Polarized light propagating in a magnetic field as a probe of millicharged fermions. Physical Review Letters, 97, https://doi.org/10.1103/physrevlett.97.140402

Possible extensions of the standard model of particle physics suggest the existence of particles with small, unquantized electric charge. Photon-initiated pair production of millicharged fermions in a magnetic field would manifest itself as a vacuum...

Loop corrections to scalar quintessence potentials (2002)
Journal Article
Doran, M., & Jaeckel, J. (2002). Loop corrections to scalar quintessence potentials. Physical Review D, Particles and fields, 66, https://doi.org/10.1103/physrevd.66.043519

The stability of scalar quintessence potentials under quantum fluctuations is investigated for both uncoupled models and models with a coupling to fermions. We find that uncoupled models are usually stable in the late universe. However, the coupling... Read More about Loop corrections to scalar quintessence potentials.
