Y-Formalism and Curved Beta-Gamma Systems
Pietro Antonio Grassi, Ichiro Oda, Mario Tonin
We adopt the Y-formalism to study beta-gamma systems on hypersurfaces. We compute the operator product expansions of gauge-invariant currents and we discuss some applications of th…
Y-formalism and ghost in the Non-minimal Pure Spinor Formalism of Superstrings
Ichiro Oda, Mario Tonin
We present the Y-formalism for the non-minimal pure spinor quantization of superstrings. In the framework of this formalism we compute, at the quantum level, the explicit form of t…
Branes in Super-AdS Backgrounds and Superconformal Theories
Paolo Pasti, Dmitri Sorokin, Mario Tonin
We demonstrate how actions for interacting superconformal field theories in (p+1)-dimensions arise as a result of gauge fixing worldvolume diffeomorphisms and fermionic kappa-symme…
Space-Time Symmetries in Duality Symmetric Models
Paolo Pasti, Dmitrij Sorokin, Mario Tonin
A way of covariantizing duality symmetric actions is proposed. As examples considered are a manifestly space-time invariant duality--symmetric action for abelian gauge fields coupl…
Twistor--like Formulation of D=10, type IIA, Superstrings
P. Pasti, M. Tonin
The twistor--like formulation of the type IIA superstring --model in D=10 is obtained by performing a dimensional reduction of the recently proposed twistor--like action of the…
Twistor-Like Formulation of Heterotic Strings
M. Tonin
In this talk new formulations of the Green--Schwarz heterotic strings in dimensions that involve commuting spinors, are reviewed. These models are invariant under --extended…
