Component on shell actions of supersymmetric 3-brane I. 3-brane in D=6

Understand

In the present and accompanying papers we explicitly construct the on-shell supersymmetric component actions for 3-branes moving in D=6 and in D=8 within the nonlinear realizations framework.

• In the first paper we apply our schema to construct the action of supersymmetric 3-brane in D=6.
• It turns out that all ingredients entering the component action can be obtained almost algorithmically by using the nonlinear realizations approach.
• Within this approach, properly adapted to the construction of on-shell component actions, we pay much attention to broken supersymmetry.
