Left-handed string and CHY amplitude at one loop
Yuqi Li, Warren Siegel
We propose a generalized left-handed (chiral) gauge choice for the genus one Riemann surface, realized through a singular gauge transformation of worldsheet coordinates. The transf…
Towards -finiteness: -deformed open string amplitude
Yuqi Li, Hao-Yu Sun
Revisiting the Coon amplitude, a deformation of the Veneziano amplitude with a logarithmic generalization of linear Regge trajectories, we scrutinize its potential origins in a wor…
Remarks on the critical dimension of left-handed string and its quasiconformal nature
Yuqi Li, Warren Siegel
The chiral string without a singular gauge limit is argued to have the same critical dimension as its corresponding conventional closed string. Thus, its central charge would be th…
Chiral Superstring and CHY Amplitude
Yuqi Li, Warren Siegel
We calculate the chiral string amplitude in pure spinor formalism and take four point amplitude as an example. The method could be easily generalized to point amplitude by comp…
