Quantized Solitons in the Extended Skyrme-Faddeev Model	2011	3	.pdf	application/pdf	1846	109	76	We have found new Hopf soliton solutions for the extended Skyrme- Faddeev model. It is a (3 + 1)-dimensional Lorentz invari- ant field theory for a triplet of scalar fields �n, living on the two-sphere S2, �n2 = 1, and defined by the Lagrangian density L = M2 ∂μ�n · ∂μ�n− 1 e2 (∂μ�n ∧ ∂ν�n) 2 + (1)	cache/ap-1358.pdf	txt/ap-1358.txt
