Compact Q-balls and Q-shells in CPN-type models

Compact Q-balls and Q-shells in CPN-type models We show that the CPN model with an odd number of scalar fields and a V-shaped potential possesses some finite energy compact solutions in the form of Q-balls and Q-shells. Such solutions were obtained in 3+1 dimensions. The Q-balls appear for N=1 and N=3, whereas the Q-shells are present for higher odd numbers N. We show that the energy of the solutions behaves as E∼|Q|5/6, where Q stands for the Noether charge. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review D American Physical Society (APS)
