Connection between particles a field in string theory

  1. Sep 7, 2014 #1
    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.

    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.

    This will probably clear it up:

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