Continuous spin and tensionless strings
نویسنده
چکیده
A classical action is proposed which upon quantisation yields massless particles belonging to the continuous spin representation of the Poincaré group. The string generalisation of the action is identical to the tensionless extrinsic curvature action proposed by Savvidy. We show that the BRST quantisation of the string action gives a critical dimension of 28. The constraints result in a number of degrees of freedom which is the same as the bosonic string.

On the Tensionless Limit of Bosonic Strings, Infinite Symmetries and Higher Spins
In the tensionless limit of string theory on flat background all the massive tower of states gets squeezed to a common zero mass level and the free theory is described by an infinite amount of massless free fields with arbitrary integer high spin. We notice that in this situation the very notion of critical dimension gets lost, the apparency of infinite global symmetries takes place, and the cl...
متن کاملA Note on Tensionless Strings in M-theory
In this article we examine the appearance of tensionless strings in M-Theory. We subsequently interpret these tensionless strings in a String Theory context. In particular, we examine tensionless strings appearing in M-Theory on S, M-Theory on S/Z2, and MTheory on T ; we then interpret the appearance of such strings in a String Theory context. Then we reverse this process and examine the appear...
متن کاملMore on Supersymmetric Tensionless Rotating
Rotating IIB strings in AdS5 × S become ultra-relativistic, and hence effectively tensionless, in the limit of large angular momentum on S. We have shown previously that such tensionless strings may preserve supersymmetry. Here we extend this result to include a class of supersymmetric tensionless strings with arbitrary SO(6) angular momentum. We close with some general comments on tensionless ...
متن کاملSix-Dimensional Tensionless Strings In The Large N Limit
When N five-branes of M-theory coincide the world-volume theory contains tensionless strings, according to Strominger’s construction. This suggests a large N limit of tensionless string theories. For the small E8 instanton theories, the definition would be a large instanton number. An adiabatic argument suggests that in the large N limit an effective extra uncompactified dimension might be obse...
متن کاملThe Holographic Dual of a SUSY Vector Model and Tensionless Open Strings
We describe a supersymmetric example of the holographic duality between 3 dimensional vector models and higher spin gauge theories in AdS4, first proposed in a bosonic context by Klebanov and Polyakov. We argue that a particular Fradkin-Vasiliev type supersymmetric higher spin gauge theory in AdS4 with 16 supersymmetries is dual to the singlet sector of bilinear operators of a free N = 4, SU(N)...
