I'm currently trying to learn Clifford algebra or more specifically spinors, in higher dimensions. My goal is to study AdS/CFT, but an essential part of learning it is to understand SUSY which then needs some element of Clifford algebra in higher dimensions.

I have consulted,
Introduction to the AdS/CFT Correspondence by Horaƫiu Năstase
Supergravity by Daniel Z. Freedman and Antoine Van Proeyen

The book by Năstase only discussed it in a section and is extremely compact, no motivation and discussion of the steps. The book by Freedman devoted two sections and is more comprehensive than Năstase, but it is still lacking in motivation with the steps and some equations.

So, I'm looking for books or lectures more devoted to Clifford algebra/spinors in higher dimensions that is tailored specifically for people pursuing AdS/CFT or quantum field theory. I believe Clifford algebra/spinors in higher dimensions resources can be extremely varied in its presentation depending on the target audience. I've searched the web for some lectures but either it is also too brief and just a list of equations or it is geared towards mathematicians with theorem-proof format.

An example of the briefness and no motivation style is to just present the higher dimensional ##\gamma##-matrices as a bunch of tensor products of ##\sigma##-matrices. My question is, why? No explanation or motivation at all, this goes on throughout the books I listed above, just listing down and checking that every equation is consistent with the previous.

FAQ: Clifford Algebra for Quantum Field Theory, Supersymmetry, Supergravity

What is Clifford Algebra and how is it used in Quantum Field Theory?

Clifford Algebra is a type of algebra that generalizes complex numbers, quaternions, and several other mathematical systems. It is particularly useful in Quantum Field Theory (QFT) for describing spinors and the algebra of gamma matrices, which are essential in the formulation of the Dirac equation for fermions. Clifford Algebra helps in the manipulation of these mathematical objects, making it easier to handle the symmetries and properties of quantum fields.

How does Clifford Algebra relate to Supersymmetry?

In Supersymmetry (SUSY), Clifford Algebra plays a crucial role in defining the algebraic structures that relate bosons and fermions. The generators of SUSY transformations form a superalgebra, which can be represented using Clifford Algebra. This mathematical framework allows for the consistent treatment of supersymmetric particles and their interactions, facilitating the construction of supersymmetric models in theoretical physics.

What role does Clifford Algebra play in Supergravity?

Supergravity is an extension of general relativity that incorporates supersymmetry. Clifford Algebra is used in Supergravity to handle the spinor fields and the gamma matrices that appear in the theory. These mathematical tools are essential for formulating the equations of motion and constraints in Supergravity, allowing for a consistent description of the gravitational interactions of supersymmetric particles.

Can Clifford Algebra simplify calculations in Quantum Field Theory?

Yes, Clifford Algebra can significantly simplify calculations in Quantum Field Theory. By providing a systematic way to handle spinors and gamma matrices, Clifford Algebra reduces the complexity of manipulating these objects. This simplification is particularly useful in higher-dimensional theories and in the computation of Feynman diagrams, where the algebraic properties of Clifford Algebra can be exploited to streamline the calculations.

Are there any prerequisites for understanding Clifford Algebra in the context of QFT, SUSY, and Supergravity?

To understand Clifford Algebra in the context of Quantum Field Theory, Supersymmetry, and Supergravity, one should have a solid background in advanced mathematics and theoretical physics. Key prerequisites include knowledge of linear algebra, group theory, differential geometry, and basic quantum mechanics. Familiarity with the principles of QFT and the fundamentals of supersymmetry and general relativity is also essential for grasping the applications of Clifford Algebra in these fields.
