Higher Fermions in Supergravity

Area of Science:

• Theoretical Physics
• High-Energy Physics
• String Theory

Background:

• Supergravity theories describe gravity in conjunction with supersymmetry.
• Describing higher-order fermion interactions is crucial for understanding quantum gravity effects.
• Ten-dimensional N=1 supergravity is a key framework in string theory and M-theory.

Purpose of the Study:

• To introduce a novel approach for describing higher-fermion terms in ten-dimensional N=1 supergravity.
• To demonstrate the utility of the generalized geometry formalism in this context.
• To simplify the analysis of actions and supersymmetry transformations.

Main Methods:

• Utilizing the generalized geometry formalism.
• Working within the second-order formalism.
• Deriving expressions for higher-fermion terms without relying on supercovariantization or superspace.

Main Results:

• The generalized geometry formalism offers a new perspective on higher-fermion terms.
• Expressions involving only five higher-fermion terms were found.
• These terms were identified across both the action and supersymmetry transformations.

Conclusions:

• The generalized geometry formalism provides an efficient and alternative method for studying supergravity.
• This formalism simplifies the description of complex terms in ten-dimensional supergravity.
• The findings contribute to a deeper understanding of quantum gravity and string theory.
