High energy scattering of highly excited strings

Regular Seminar Vladimir Rosenhaus (IAS)

14:00 IC
room zoom

The n-point tachyon amplitude is a classic and well-known result in bosonic string theory. Rather than studying tachyon amplitudes, we will compute scattering amplitudes involving highly excited string states. Along the way we review and elaborate on the DDF construction of string vertex operators, and describe properties of a generic excited string. Based on work in progress with D. Gross.
