Yang-Mills action from open superstring field theory
(2003-09-01)
We calculate the effective action for nonabelian gauge bosons up to quartic order using WZW-like open superstring field theory. After including level zero and level one contributions, we obtain with 75% accuracy the ...
One loop conformal invariance of the superstring in an AdS(5) x S-5 background
(Int School Advanced Studies, 2002-12-01)
It is proven that the pure spinor superstring in an AdS(5) x S-5 background remains conformally invariant at one loop level in the sigma model perturbation theory.
Pure spinor partition function and the massive superstring spectrum
(Int School Advanced Studies, 2008-08-01)
We explicitly compute up to the fifth mass-level the partition function of ten-dimensional pure spinor worldsheet variables including the spin dependence. After adding the contribution from the (x(mu), theta(alpha), p(alpha)) ...
Explaining the pure spinor formalism for the superstring
(Int School Advanced Studies, 2008-01-01)
After adding a pair of non-minimal fields and performing a similarity transformation, the BRST operator in the pure spinor formalism is expressed as a conventional-looking BRST operator involving the Virasoro constraint ...

Some superstring amplitude computations with the non-minimal pure spinor formalism
(Int School Advanced Studies, 2006-11-01)
We use the non-minimal pure spinor formalism to compute in a super-Poincare covariant manner the four-point massless one and two-loop open superstring amplitudes, and the gauge anomaly of the six-point one-loop amplitude. ...
Covariant map between Ramond-Neveu-Schwarz and pure spinor formalisms for the superstring
(Springer, 2014-04-04)
A covariant map between the Ramond-Neveu-Schwarz (RNS) and pure spinor formalisms for the superstring is found which transforms the RNS and pure spinor BRST operators into each other. The key ingredient is a dynamical ...
Twistor origin of the superstring
(Springer, 2015-03-24)
After introducing a d=10 pure spinor lambda(alpha), the Virasoro constraint partial derivative x(m)partial derivative x(m) = 0 can be replaced by the twistor-like constraint partial derivative x(m) (gamma(m)lambda)(alpha) ...
