2. Brane - Wikipedia

   en.wikipedia.org/wiki/Brane

   Open strings attached to a pair of D-branes. In string theory, a string may be open (forming a segment with two endpoints) or closed (forming a closed loop). D-branes are an important class of branes that arise when one considers open strings. As an open string propagates through spacetime, its endpoints are required to lie on a D-brane.

3. D-brane - Wikipedia

   en.wikipedia.org/wiki/D-brane

   The arrangement of D-branes constricts the types of string states which can exist in a system. For example, if we have two parallel D2-branes, we can easily imagine strings stretching from brane 1 to brane 2 or vice versa. (In most theories, strings are oriented objects: each one carries an "arrow" defining a direction along its length.) The ...

4. Brane cosmology - Wikipedia

   en.wikipedia.org/wiki/Brane_cosmology

   In the bulk model, at least some of the extra dimensions are extensive (possibly infinite), and other branes may be moving through this bulk. Interactions with the bulk, and possibly with other branes, can influence our brane and thus introduce effects not seen in more standard cosmological models.

5. NS5-brane - Wikipedia

   en.wikipedia.org/wiki/NS5-brane

   In string theory, the NS5-brane is a fundamental extended object in six-dimensional spacetime that carries magnetic charge under the Neveu–Schwarz B-field.The tension of the NS5-brane is inversely proportional to the Newton gravitational constant, making it a solitonic object of the theory.

6. M-theory - Wikipedia

   en.wikipedia.org/wiki/M-theory

   For example, a point particle can be viewed as a brane of dimension zero, while a string can be viewed as a brane of dimension one. It is also possible to consider higher-dimensional branes. In dimension p, these are called p-branes. Branes are dynamical objects which can propagate through spacetime according to the rules of quantum mechanics.

7. Randall–Sundrum model - Wikipedia

   en.wikipedia.org/wiki/Randall–Sundrum_model

   The model is a braneworld theory developed while trying to solve the hierarchy problem of the Standard Model.It involves a finite five-dimensional bulk that is extremely warped and contains two branes: the Planckbrane (where gravity is a relatively strong force; also called "Gravitybrane") and the Tevbrane (our home with the Standard Model particles; also called "Weakbrane").
