2. 1. Spin-offs from Stretching a Point : Strings, Branes and Higher Spin

   Author : Peter Rajan; Ulf Danielsson; Anton Alekseev; Esko Keski-Vakkuri; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Theoretical physics; String theory; D-branes; Higher-spin gauge theory; Matrix models; Non-commutative open string theory; Teoretisk fysik; Physics; Fysik;

   Abstract : String theory has proved to be a valuable theoretical laboratory for probing gravity and gauge theory in a unified framework. In this thesis some of the exciting spin-offs of string theory such as branes and higher spin are studied. After a review of the basics of string theory the four papers of the thesis are discussed.

4. 2. A Kerr-full Study of Higher-Spin Amplitudes : An on-shell construction of higher-spin amplitudes for black holes and strings

   Author : Paolo Pichini; Henrik Johansson; Donal O'Connell; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; scattering amplitudes; higher-spin theory; black holes; string theory; gravitational waves; Theoretical Physics; Teoretisk fysik;

   Abstract : Recently, it was shown that Kerr black holes can be described via the classical infinite-spin limit of a special class of scattering amplitudes in a massive higher-spin quantum field theory. Although this approach has successfully obtained state-of-the-art results for spinning black-hole binaries, only the three-point amplitude that describes Kerr is known in full generality and a full understanding of the underlying Lagrangian is still missing.

5. 3. Dualities, Symmetries and Unbroken Phases in String Theory : Probing the Composite Nature of the String

   Author : Johan Engquist; Joseph Minahan; Charlotte Kristjansen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Theoretical Physics; String Theory; M-Theory; Higher Spin Gauge Theory; Super Yang-Mills Theory; Anti-de Sitter Spacetime; Singletons; Massless Higher Spin Gauge Fields; AdS CFT Correspondence; Spin Chains; Semiclassical Strings; Tensionless Limits; Conformal Symmetry; Supersymmetry; Higher Spin Gauge Symmetry; Integrability; Fysik; Physics; Fysik;

   Abstract : The thesis treats aspects of string/M-theory in anti-de Sitter spacetimes and their supersymmetric completions. By applying the AdS/CFT correspondence, as well as models of spin chains and singletons, we try to attain a better understanding of the underlying symmetries and the unbroken phases of string/M-theory.

6. 4. Torn, Spun and Chopped : Various Limits of String Theory

   Author : Fredric Kristiansson; Ulf Danielsson; Per Sundell; Bo Sundborg; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Theoretical physics; String theory; D-branes; Non-commutative open string theory; AdS CFT; Higher spin gauge theory; BMN; String bits; Fermion doubling; Teoretisk fysik; Physics; Fysik;

   Abstract : For the first time in the history of physics we stand in front of a theory that might actually serve as a unification of it all - string theory. It provides a self-consistent framework for gravity and quantum mechanics, which naturally incorporates matter and gauge interactions of the type seen in the standard model. READ MORE

7. 5. (2,0) Theory and Higher Spin: Twisting, Turning and Spinning Towards Higher Energies

   Author : Hampus Linander; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : This thesis investigates an enigmatic six-dimensional quantum theory known as (2,0) theory and a three dimensional conformal theory of higher spin. The former has resisted an explicit construction as a quantum field theory, yet its existence can be inferred from string theory and M-theory where it plays a prominent role. READ MORE
