Scattering in the adjoint sector of the c = 1 Matrix Model

Understand

Closed string tachyon emission from a traveling long string in Liouville string theory is studied.

• The exact collective field Hamiltonian in the adjoint sector of the c=1 matrix model is computed to capture the interaction between the tip of the long string and the closed string tachyon field.
• The amplitude for emission of a single tachyon quantum is obtained in a closed form using the chiral formalism.
