string theory
In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. String theory describes how these strings propagate through space and interac ...
, including related areas such as
supergravity,
supersymmetry
In a supersymmetric theory the equations for force and the equations for matter are identical. In theoretical and mathematical physics, any theory with this property has the principle of supersymmetry (SUSY). Dozens of supersymmetric theories e ...

How are these related?
There is only one dimensional constant in string theory, and that is the inverse string tension
with units of area. Sometimes
is therefore replaced by a length
. The string tension is mostly defined as the fraction
:
Tension is energy or work per unit length. In natural units
and
, and hence
has dimension of length/energy or length/mass. Since
has the dimension of action, i.e. momentum times length, it follows that in natural units mass =1/length, and so
has the unit of area.
The slope
of a Regge trajectory
in
Regge theory
Regge may refer to
* Tullio Regge (1931-2014), Italian physicist, developer of Regge calculus and Regge theory
* Regge calculus, formalism for producing simplicial approximations of spacetimes
* Regge theory, study of the analytic properties of ...
is the derivative of spin
or angular momentum with respect to mass-squared, i.e.
:
Since angular momentum is moment of momentum
, i.e. length times mass with
,
is dimensionless in natural units, and
has units of
or area like the inverse string tension.
