Connection between particles a field in string theory

In summary, the string entity is not directly related to its underlying field. A brane, which is a D-dimensional object, is also not the analog of a field. However, both strings and particles are one- and zero-dimensional objects, respectively, while a D-brane is a D-dimensional object. Additionally, branes can have a different composition of particles than strings. This concept can be further explained through string field theory.

Im a trying to understand how the string entity relates to its underlying field. Is the field a brane and the string the partice?

No. A brane is not the analog of a field, it is another type of object. In the sense that a string is a one-dimensional object (and a particle is a zero-dimensional object), a D-brane is a D-dimensional object.

Thank you.

A brane is the analog of space-time with D dimensions, with the caveat that often gravitons can live on branes that other SM particles (i.e. string excitations) are not permitted to be present in.

Thank you. That was just what I was looking for!
 

Related to Connection between particles a field in string theory

What is string theory and how does it relate to particle physics?

String theory is a theoretical framework that aims to reconcile quantum mechanics with general relativity. It proposes that particles are not point-like objects, but rather tiny vibrating strings. These strings interact with each other and with the surrounding space-time to form the particles we observe in the universe.

What is the role of fields in string theory?

Fields play a crucial role in string theory as they describe the interactions between strings and other particles. In string theory, fields are represented by vibrational modes of the strings, and the different types of particles are determined by the specific vibrational pattern of the fields.

How are particles and fields connected in string theory?

In string theory, particles and fields are connected through the concept of duality. This means that certain physical systems that appear different at first glance are actually equivalent. For example, a theory with particles can be mathematically equivalent to a theory with fields, and vice versa.

What are the implications of the connection between particles and fields in string theory?

The connection between particles and fields in string theory has significant implications for our understanding of the fundamental building blocks of the universe. It suggests that particles and fields are not separate entities, but rather different manifestations of the same underlying structure of strings and their vibrations.

How does the connection between particles and fields in string theory impact our current understanding of the universe?

The connection between particles and fields in string theory challenges our current understanding of the universe and opens up new possibilities for studying and explaining the physical laws that govern it. It offers a potential solution to some of the biggest mysteries of physics, such as the unification of all fundamental forces and the existence of dark matter.
