English[edit]
Etymology[edit]
Q (“charge”) + ball, coined by physicist Sidney Coleman.^{[1]}
Noun[edit]
Qball (plural Qballs)
 A charged soliton that represents the lowest possible energy state of its components and is therefore stable.

2001, Tuomas Multamäki, “Qball Collisions in the MSSM”, in Strong and Electroweak Matter 2000, page 348:
 Qball collisions are studied numerically on a two dimensional lattice for a range of Qball charges.

2008, Roger Ebert, Roger Ebert's Movie Yearbook 2009, page 880:
 If you're going to fly inside Mercury's orbit and hurl a bomb into the sun to burst its Qball (nontopological soliton) into pieces, I suggest that home may require a theoretical solution.

2009, Noah Graham, Markus Quandt and Herbert Weigel, Specral Methods in Quantum Field Theory, page 171:
 A complex scalar theory in three dimensions with a cubic coupling can support classically stable, timedependent, nontopological solutions to the equations of motion that carry a global charge Q, called Qballs.
