Excited Q-Balls
Yahya Almumin, Julian Heeck, Arvind Rajaraman +1
Complex scalars in U(1)-symmetric potentials can form stable Q-balls, non-topological solitons that correspond to spherical bound-state solutions. If the U(1) charge of the Q-ball…
Isotope dependence of muon decay in orbit
Julian Heeck, Robert Szafron, Yuichi Uesaka
The decay of a muon that is bound to a nucleus poses an unavoidable background for experiments such as Mu2e, COMET, and DeeMe searching for lepton-flavor-vi…
Proca Q-balls and Q-shells
Julian Heeck, Arvind Rajaraman, Rebecca Riley +1
Non-topological solitons such as Q-balls and Q-shells have been studied for scalar fields invariant under global and gauged U(1) symmetries. We generalize this framework to include…
The Ubiquity of Gauged Q-Shells
Julian Heeck, Arvind Rajaraman, Christopher B. Verhaaren
Non-topological gauged soliton solutions called Q-balls arise in many scalar field theories that are invariant under a U(1) gauge symmetry. The related, but qualitatively distinct,…
Mapping Gauged Q-Balls
Julian Heeck, Arvind Rajaraman, Rebecca Riley +1
Scalar field theories with particular U(1)-symmetric potentials contain non-topological soliton solutions called Q-balls. Promoting the U(1) to a gauge symmetry leads to the more c…
Feebly-Interacting Particles:FIPs 2020 Workshop Report
Prateek Agrawal, Martin Bauer, James Beacham +43
With the establishment and maturation of the experimental programs searching for new physics with sizeable couplings at the LHC, there is an increasing interest in the broader part…
