String interactionsBranched coveringsHitchin systemsMatrix string theory, i.e. the two-dimensional U ( N ) SYM with N = (8,8) supersymmetry, has classical BPS solutions that interpolate between an initial and a
String theory includes both open strings, which have two distinct endpoints, and closed strings making a complete loop. The two types of string behave in slightly different ways, yielding two different spectra. For example, in most string theories, one of the closed string modes is the graviton...
Before we can see what the string-theoretic UV completion of gravity has to say about the real world, a few more formal developments are necessary. First, we want to understand at least in principle how scattering amplitudes and loop effects are calculat

It covers perturbative string theory, the unity of string interactions, black holes and their microscopic entropy, the AdS/CFT correspondence and its applications, matrix model tools for string theory, and more. It also includes 600 exercises and serves as a self-contained guide to the literature...
Page 3 of 9 - String Theory Update - posted in Science! Astronomy & Space Exploration, and Others: Every theory that are mathematically coherents but not refuted yet should be equally considerated then. To put all the eggs in the same basket is not a w
The SFT action encapsulates the dynamics of these string fields and includes terms corresponding to the free propagation of strings and their interactions. In string theory, a covariant open bosonic string field theory stands as a significant milestone, offering a powerful framework for understanding ...
, we evaluate a functional average of the square of string contact interactions which is partial to the partition function and compare the result with the expectation value in the su (2) gauge theory of the wilson loop. finally, we summarise our results in sect. 6 . 2 production of ...
String theory provides the most developed contemporary approach to study how the Standard Model parameters may arise from a unified theory of the gauge and gravitational interactions. For this purpose several models that repro- duce the spectrum of the Minimal Supersymmetric Standard Model have been ...
