THE FOUR-POINT FUNCTION ON A SURFACE OF INFINITE GENUS
Simon Davis · Modern Physics Letters A · 1994
The four-point function arising in the scattering of closed bosonic strings in their tachyonic ground state is evaluated on a surface of infinite genus. The amplitude has poles corresponding to physical intermediate states and divergences at the boundary of moduli space, but no new types of divergences result from the infinite number of handles. The implications for the universal moduli space approach to string theory are briefly discussed.
