String theory, in particle physics, a theory that attempts to merge quantum mechanics with Albert Einstein’s general theory of relativity. The name string theory comes from the modeling of subatomic particles as tiny one-dimensional ’stringlike’ entit
That was the beginning of one string theory spin-off: M-theory. The "M" is likely inspired by higher-dimensional objects called membranes, Taylor said, but since the theory has no concrete mathematical equations, the "M" remains a placeholder with no official meaning. "It was really a ...

The correspondence between free second quantized and first quantized theories implies that the equation of motion of any free string field theory is Q桅 = 0. The string have a fields have a fixed, but not unique, total ghost number. In most cases the equations of motion do not follow from...
The theory is simple in this case: the Lagrange multiplier Gij imposes the instanton equations F = ∗F , (3.14) with the dynamics of the theory reducing to supersymmetric quantum mechanics on their moduli space. The spacetime symmetries of this action were discussed in [26], forming the ...
String theory and number theory have common ground in a specific kind of elliptic curve from a torus. Toruses aren't just for compressing atoms: these curves represent torus cross-sections. The secret to the link is in modularity and invariance in the equations representing the curves.Scientists...
it is an invertible theory that gives us a way of defining the phase of the partition function ofby evaluating the partition function ofon amanifold with boundary (see [21] for the original discussion in the case of anomalies of fermions). The theory, attached to its anomaly theory, arises...
In string theory, imposing the Dirichlet condition on the open string is interpreted as the string being bound to what is called the D-branes. So the momentum of the string is no longer stored at this time, but the "momentum of the string and D-branes" is....

These equations indicate that String Theory does bypass the Velo–Zwanziger problem, i.e. the loss of causality experienced by a massive high-spin field minimally coupled to electromagnetism. Moreover, we provide some evidence that only the first Regge trajectory can be described in isolation and ...
