String coupling constant

WebString theories have a coupling constant. It determines the probability that a 1-dimensional string of energy will separate into two separate energy strings. But unlike in particle theories, the string coupling constant is not just a number, but depends on one of the oscillation modes of the string. WebIn string theory, the dilaton field ϕ describes how strongly strings couple to one another. More precisely, in perturbation theory, the open string coupling constant is the …

Webstring coupling constant is no fundamental parameter that can be set to a certain value but corresponds to the value of a quantum eld (the dilaton). Selecting the value of the string coupling therefore is a matter of the theory’s dynamics.
