Sectors in String theory and the N-S N-S sector

In summary, the conversation is about someone asking for an explanation or resources about the concept of "sector" in string theory. They also inquire about the N-S N-S sector and its connection to fermions. A helpful link is provided for a pedagogic introduction to string theory that includes an explanation of sectors. The person expressing gratitude is referred to as "demystifier".

Hey folks,

Can somone explain what is meant by a 'sector' in string theory, or provide links/refs. I've tried a search on google and xxx.lanl.gov but nothing very useful turns up.

Also, what is the N-S N-S sector (I know it stands for Neveu Schwarz). I think its a description of fermions that are periodic / anti periodic on a closed string, is this about right??

Any help appreciated!

Great, looks like what I'm looking for. Thanks demystifier!
 

Related to Sectors in String theory and the N-S N-S sector

1. What is the N-S N-S sector in string theory?

The N-S N-S sector refers to a sector in string theory that contains strings with both Neveu-Schwarz (N-S) boundary conditions for left-moving and right-moving modes. This sector is important because it includes the graviton, which is the particle associated with the gravitational force.

2. What is the significance of the N-S N-S sector in string theory?

The N-S N-S sector is significant because it contains the graviton, which is responsible for the force of gravity. This means that the N-S N-S sector plays a crucial role in understanding the nature of gravity in the context of string theory.

3. How does the N-S N-S sector differ from other sectors in string theory?

The N-S N-S sector differs from other sectors in string theory because it contains both left-moving and right-moving modes with N-S boundary conditions. Other sectors may have different combinations of boundary conditions, leading to different types of particles in the theory.

4. Can the N-S N-S sector be experimentally tested?

Yes, the N-S N-S sector can be experimentally tested through high-energy particle collisions. By colliding particles at extremely high energies, scientists can recreate the conditions of the early universe when strings were believed to exist. This allows for testing of predictions made by string theory, including the existence of particles in the N-S N-S sector.

5. How does the N-S N-S sector contribute to our understanding of the universe?

The N-S N-S sector contributes to our understanding of the universe by providing a theoretical framework for describing the fundamental forces of nature. It also helps to reconcile the theories of general relativity and quantum mechanics, which have been difficult to reconcile using traditional methods. By studying the N-S N-S sector in string theory, scientists hope to gain a better understanding of the origins and nature of the universe.
