  2. Lund string model - Wikipedia

    en.wikipedia.org/wiki/Lund_string_model

    In particle physics, the Lund string model is a phenomenological model of hadronization. It treats all but the highest- energy gluons as field lines, which are attracted to each other due to the gluon self-interaction and so form a narrow tube (or string) of strong color field .

  3. String (physics) - Wikipedia

    en.wikipedia.org/wiki/String_(physics)

    String vibrations. In physics, a string is a physical entity postulated in string theory and related subjects. Unlike elementary particles, which are zero-dimensional or point-like by definition, strings are one-dimensional extended entities. Researchers often have an interest in string theories because theories in which the fundamental ...

  4. String theory - Wikipedia

    en.wikipedia.org/wiki/String_theory

    String theory is a broad and varied subject that attempts to address a number of deep questions of fundamental physics. String theory has contributed a number of advances to mathematical physics, which have been applied to a variety of problems in black hole physics, early universe cosmology, nuclear physics, and condensed matter physics, and ...

  5. Type II string theory - Wikipedia

    en.wikipedia.org/wiki/Type_II_string_theory

    At low energies, type IIA string theory is described by type IIA supergravity in ten dimensions which is a non-chiral theory (i.e. left–right symmetric) with (1,1) d=10 supersymmetry; the fact that the anomalies in this theory cancel is therefore trivial.

  6. Polyakov action - Wikipedia

    en.wikipedia.org/wiki/Polyakov_action

    In physics, the Polyakov action is an action of the two-dimensional conformal field theory describing the worldsheet of a string in string theory.It was introduced by Stanley Deser and Bruno Zumino and independently by L. Brink, P. Di Vecchia and P. S. Howe in 1976, [1] [2] and has become associated with Alexander Polyakov after he made use of it in quantizing the string in 1981. [3]

  7. Large extra dimensions - Wikipedia

    en.wikipedia.org/wiki/Large_extra_dimensions

    Traditionally, in theoretical physics, the Planck scale is the highest energy scale and all dimensionful parameters are measured in terms of the Planck scale. There is a great hierarchy between the weak scale and the Planck scale, and explaining the ratio of strength of weak force and gravity / = is the focus of much of beyond-Standard-Model physics.

  8. F-theory - Wikipedia

    en.wikipedia.org/wiki/F-theory

    In theoretical physics, F-theory is a branch of string theory developed by Iranian-American physicist Cumrun Vafa. [1] The new vacua described by F-theory were discovered by Vafa and allowed string theorists to construct new realistic vacua — in the form of F-theory compactified on elliptically fibered Calabi–Yau four-folds.

  9. Introduction to M-theory - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_M-theory

    The Standard Model is the set of rules that describes the interactions of these particles. In the 1980s, a new mathematical model of theoretical physics, called string theory, emerged. It showed how all the different subatomic particles known to science could be constructed by hypothetical one-dimensional "strings", infinitesimal building ...
