Bosonic description of spinning strings in 2+1 dimensions.

چکیده
We write down a general action principle for spinning strings in 2 + 1 dimensional space-time without introducing Grassmann variables. The action is written solely in terms of coordinates taking values in the 2 + 1 Poincaré group, and it has the usual string symmetries, i.e. it is invariant under a) diffeomorphisms of the world sheet and b) Poincaré transformations. The system can be generalized to an arbitrary number of space-time dimensions, and also to spinning membranes and p-branes.

The Poincaré coset models ISO(d-1,1)/IR and T-duality
We generalize a family of Lagrangians with values in the Poincaré group ISO(d − 1, 1), which contain the description of spinning strings in flat (d− 1) + 1 dimensions, by including symmetric terms in the world-sheet coordinates. Then, by promoting a subgroup H ∼ IR, n ≤ d, which acts invariantly from the left on the element of ISO(d − 1, 1), to a gauge symmetry of the action, we obtain a family...
متن کاملDeriving Spin of the Bosonic String
Exploiting the strict analogy between the motion of strings and extended-like spinning particles, we propose an original kinematical formulation of the spin of bosonic strings and give, for the first time, an analytical derivation of an explicit expression of the string spin vector.

I present a new class of topological string theories, and discuss them in two dimensions as candidates for the string description of large-N QCD. The starting point is a new class of topological sigma models, whose path integral is localized to the moduli space of harmonic maps from the worldsheet to the target. The Lagrangian is of fourth order in worldsheet derivatives. After gauging worldshe...
متن کاملThomson scattering of chiral tensors and scalars against a self-dual string
We give a non-technical outline of a program to study the (2, 0) theories in six space-time dimensions. Away from the origin of their moduli space, these theories describe the interactions of tensor multiplets and self-dual spinning strings. We argue that if the ratio between the square of the energy of a process and the string tension is taken to be small, it should be possible to study the dy...
متن کاملIntegrability of spinning particle motion in higher-dimensional rotating black hole spacetimes.
We study the motion of a classical spinning particle (with spin degrees of freedom described by a vector of Grassmann variables) in higher-dimensional general rotating black hole spacetimes with a cosmological constant. In all dimensions n we exhibit n bosonic functionally independent integrals of spinning particle motion, corresponding to explicit and hidden symmetries generated from the princ...
