Polylogarithms in tree-level open string calculations
If you have a question about this talk, please contact Dr Dorigoni.
Recent investigations have revealed a beautiful structure in open string tree-level amplitudes: they can be organized in terms of classes of multiple zeta values, which in turn provide the link to a related Hopf-algebra structure. While the open string tree-level function can be written in an extraordinarily simple form, the actual calculation was subject to difficulties and thus confined to low multiplicities and low orders in the inverse string tension. In this talk I will describe how to employ polylogarithms in order to algebraically obtain results for any multiplicity efficiently. Those results can be used to test the underlying algebra for previously unaccessible scenarios.
