Query: Thin-Walled Higgs Assisted Q-balls from Pseudo-Nambu-Goldstone Bosons   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-Nambu-Golstone bosons (pNGBs). In particular, we consider
the so-called thin-wall limit where volume energy dominates over surface
energy. It is known that the leading order chiral Lagrangian alone does not
support such multi-field solutions. Augmented by the Higgs, however, we do
indeed find that such solutions exist. We then study their properties
numerically and, in various limits, analytically. Furthermore, since we
consider a mirror-world-like model where the pNGBs are composite states of
fundamental fermions, the question of Fermi repulsion in the high density bulk
of the Q-ball plays a central role in determining its properties. The main
effect is that when the parameter controlling the Fermi repulsion increases
beyond a critical value, the radius of the Q-ball increase and continues to
increase while the Q-ball becomes more weakly bound. As a result, there are
Q-ball solutions with radii well exceeding a femtometer which would interact
with nuclei in direct detection experiments via momentum-dependent form factors
making their signatures striking. We leave the question of the production and
direct detection of these Q-balls to a future study.
