Massive Vertex Operators and Conformal Algebra of the Bosonic Open String Theory in Flat Space-time
Chuan-Tsung Chan, Wei-Ming Chen
A systematic scheme is developed for solving conformal algebra of the massive vertex operators in the old covariant first quantized string theory. Using the first massive level in…

Vertex Operators and Scattering Amplitudes of the Bosonic Open String Theory in the Linear Dilaton Background
Chuan-Tsung Chan, Wei-Ming Chen
The operator formalism of the first quantized string theory is applied to the stringy excitations in the linear dilaton background. In particular, the normal-ordered vertex operato…
