Compact Q-balls and Q-shells in the CPN type models
Published 4 Apr 2017 in hep-th | (1704.01132v1)
Abstract: We show that the CPN model with odd number of scalar fields and V-shaped potential possesses finite energy compact solutions in the form of Q-balls and Q-shells. The solutions were obtained in 3+1 dimensions. Q-balls appears for N=1 and N=3 whereas Q-shells are present for higher odd values of N. We show that energy of these solutions behaves as E~|Q|5/6, where Q is the Noether charge.
