Q-balls with Multiple Charges and Cores
Olivier Lennon
Q-balls -- whether in the single-field or multi-field context -- are usually studied in theories containing only one stabilising symmetry. However, this is not the most general sce…
Multi-Field Q-balls with Real Scalars
Olivier Lennon
Multi-field Q-balls, in which some, but not all, of the constituent fields are real scalars, are studied. Uncharged fields may classically contribute to Q-balls provided that their…
Non-Canonical Q-balls
Olivier Lennon
Theories possessing non-canonical kinetic terms are often studied for Q-ball states in an ad-hoc manner. This paper seeks to generalise their study for both thin- and thick-wall Q-…
Thin-Walled Higgs Assisted Q-balls from Pseudo-Nambu-Goldstone Bosons
Fady Bishara, Olivier Lennon
We consider the question of whether Q-balls can exist in a chiral Lagrangian truncated at leading order when, in addition, the Standard Model Higgs boson couples to the pseudo-Namb…
Black Hole Genesis of Dark Matter
Olivier Lennon, John March-Russell, Rudin Petrossian-Byrne +1
We present a purely gravitational infra-red-calculable production mechanism for dark matter (DM). The source of both the DM relic abundance and the hot Standard Model (SM) plasma i…
Higgs Assisted Q-balls from Pseudo-Nambu-Goldstone Bosons
Fady Bishara, George Johnson, Olivier Lennon +1
Motivated by recent constructions of TeV-scale strongly-coupled dynamics, either associated with the Higgs sector itself as in pseudo-Nambu-Goldstone boson (pNGB) Higgs models or i…
