Two types of boson stars in $U (1)$ gauged $3 + 1$ -dimensional $O (3)$ sigma-model

Jutta Kunz, Aliaksei Mikhaliuk, Yakov Shnir

We investigate boson stars in an $O (3)$ scalar field theory with a symmetry-breaking potential. By constructing numerically spherically symmetric solutions, we demonstrate that the…

Boson stars in the $U (1)$ gauged 3+1 dimensional $O (3)$ sigma-model

Yakov Shnir, Aliaksei Mikhaliuk

We study regular self-gravitating non-topological soliton solutions of the $U (1)$ gauged non-linear $O (3)$ sigma model with the usual kinetic term and a simple symmetry breaking po…

$U (1)$ gauged non-topological solitons in the 3+1 dimensional $O (3)$ sigma-model

Luiz A. Ferreira, Aliaksei Mikhaliuk, Yakov Shnir

We present and study new non-topological soliton solutions in the $U (1)$ gauged non-linear $O (3)$ sigma model with a symmetry breaking potential in 3+1 dimensional flat space-time.…
