DESCRIPTION:Hopf solitons arise in deformations of a deformed version of t
he O(3) sigma model and possess topological charge described by the Hopf i
ndex\, which cannot be written locally. Gorsky Shifman and Yung proposed a
more field-theoretical model that reduces to the sigma model at hand\, an
d constructed within it an object with a non-zero Hopf index.\n\nWe descri
be the construction of such an object\, in particular in the case where it
can be considered to be BPs i.e. acquiring extra stability through preser
vation of supercharges in the theory.\n\nhttps://indico.in2p3.fr/event/178
