“…Note that one can not see any non-Abelian structure in such description, as it includes the description of just the bound state of p fundamental strings and q super-D1-branes, but not of the excitations over such bound state, which are described by non-Abelian SU(q) SYM theory in the linearized approximation [10]. We hope that en effective Lagrangian description of a system of q coincident super-Dp-branes interacting through an exchange by fundamental superstrings can be found by working out the recently proposed approach to the action of interacting superbrane systems [45].…”

It is proved that a basic superembedding equation for the 2-dimensional worldsheet superspace Σ (2|8+8) embedded into D=10 type IIB superspace M (10|16+16) provides a universal, S-duality invariant description of a fundamental superstring and super-D1-brane. We work out generalized action principle, obtain superfield equations of motion for both these objects and find how the S-duality transformations relate the superfield equations of superstring and super-D1-brane.The superembedding of 6-dimensional worldsheet superspace Σ (6|16) into the D=10 type IIB superspace M (10|16+16) will probably provide a similar universal description for the set of type IIB super-NS5-brane, super-D5-brane and a Kaluza-Klein monopole (super-KK5-brane).

“…Recently an approach to obtain a supersymmetric action functional for a coupled system of interacting superbranes has been proposed 1,2 . The aim of the study 1,2 was to construct a basis for a future search for new solitonic solutions of worldvolume equations of superbranes and of supergravity equations with a complicated system of brane sources.…”

We present an action functional and derive equations of motion for a coupled system of a bosonic Dp-brane and an open string ending on the Dp-brane. With this example we address the key issues of the recently proposed method 1,2 for the construction of manifestly supersymmetric action functionals for interacting superbrane systems. We clarify, in particular, how the arbitrariness in sources localized on the intersection 1,2 is related to the standard description of the flat D-branes as rigid planes where the string for endpoints 'live'.

In search for a dynamical description of Q7-branes, which were known as solutions of supergravity equations and then conjectured to be dynamical objects of type IIB string theory, we study the superembedding description of 7-branes in curved type IIB supergravity superspace. With quite minimal and natural assumptions we have found that there is no place for Q7-branes as dynamical branes in superembedding approach. As Q7-brane was also considered as a bound state of two SD7-branes (this is to say of two 7-branes related to the D7-brane by different SL(2) transformation), our study might give implications for the old-standing problem of the covariant and supersymmetric description of multiple Dirichlet p-brane systems. SO(1,9) SO(1,7)×SO(2) moving frame variables (also called Lorentz harmonics) 34 Appendix D. Induced worldvolume superspace geometry for 7-branes 36Appendix E. Derivation of and complete form of some equations 38 1 STV is for Sorokin, Tkach and Volkov, the authors of the pioneer paper [22]. (See also [23,24] for related studies). Such actions are known for superparticles and superstrings in superspaces with up to 16 supersymmetries, including the heterotic string without heterotic fermions [25], as well as for lower dimensional supermembranes (see [26, 27] and [16] for review and further references), but are not known neither for D=10 type II superbranes nor for D=11 M-branes. The problem appears also for heterotic string, on the stage when one tries to include heterotic fermions (or heterotic bosons). A number of approaches to superfield description of heterotic fermions were proposed [28,29], but the most successful of them [29] is restricted to the case of SO(4) group, rather than SO(32) or E 8 ⊗ E 8 charactersitic for the anomaly free heterotic string theory.2 See [32] for an earlier approach to the action for heterotic string similar to the ones in [31,30]. 3 The same conclusion, and also an expression for the (bosonic) Wess-Zumino term in terms of gauge potentials and pull-backs of supergravity fields can be found in [2].
