Gravitational Scattering Amplitudes and Closed String Field Theory in the Proper-Time Gauge
Taejin Lee
We construct a covariant closed string field theory by extending recent works on the covariant open string field theory in the proper-time gauge. Rewriting the string scattering am…
Solving Lauricella String Scattering Amplitudes through Recurrence Relations
Sheng-Hong Lai, Jen-Chi Lee, Taejin Lee +1
We show that there exist infinite number of recurrence relations valid for all energies among the open bosonic string scattering amplitudes (SSA) of three tachyons and one arbitrar…
String Scattering Amplitudes and Deformed Cubic String Field Theory
Sheng-Hong Lai, Jen-Chi Lee, Yi Yang +1
We study string scattering amplitudes by using the deformed cubic string field theory which is equivalent to the string field theory in the proper-time gauge. The four-string scatt…
Covariant Open String Field Theory on Multiple -Branes
Taejin Lee
We study covariant open bosonic string field theories on multiple -branes by using the deformed cubic string field theory which is equivalent to the string field theory in the…
Deformation of the Cubic Open String Field Theory
Taejin Lee
We study a consistent deformation of the cubic open bosonic string theory in such a way that the non-planar world sheet diagrams of the perturbative string theory are mapped onto t…
