Superspace Expansion of The 11D Linearized Superfields in The Pure Spinor Formalism, and The Covariant Vertex Operator
Maor Ben-Shahar, Max Guillen
11D pure spinors have been shown to successfully describe 11D supergravity in a manifestly super-Poincaré covariant manner. The feasibility of its actual usage for scattering ampli…
Taming the 11D pure spinor b-ghost
Max Guillen
We provide an alternative compact expression for the 11D pure spinor b-ghost by introducing a new set of negative ghost number operators made out of non-minimal pure spinor variabl…
Green-Schwarz and Pure Spinor Formulations of Chiral Strings
Max Guillen
Bosonic and RNS chiral strings have been defined from a singular gauge fixing of the respective Polyakov and spinning string actions, enforcing, among other things, the finite natu…
10D Super-Yang-Mills Scattering Amplitudes From Its Pure Spinor Action
Maor Ben-Shahar, Max Guillen
Using the pure spinor master action for 10D super-Yang-Mills in the gauge , tree-level scattering amplitudes are calculated through the perturbiner method, and shown t…
One-loop matrix elements of effective superstring interactions: -expanding loop integrands
Alex Edison, Max Guillen, Henrik Johansson +2
In the low-energy effective action of string theories, non-abelian gauge interactions and supergravity are augmented by infinite towers of higher-mass-dimension operators. We propo…
Scattering Massive String Resonances through Field-Theory Methods
Max Guillen, Henrik Johansson, Renann Lipinski Jusinskas +1
We present a new method, exact in , to explicitly compute string tree-level amplitudes involving one massive state and any number of massless ones. This construction relies on…
A Pure Spinor Twistor Description of the Superparticle
Diego García Sepúlveda, Max Guillen
We present a novel twistor formulation of the ten-dimensional massless superparticle. This formulation is based on the introduction of pure spinor variables through a field redefin…
Pure spinors and supergravity
Max Guillen
In this Thesis we study first- and second-quantized approaches describing supergravity using pure spinor variables. We introduce the so-called pure spinor superpartic…
A Pure Spinor Twistor Description of Ambitwistor Strings
Diego García Sepúlveda, Max Guillen
We present a novel ten-dimensional description of ambitwistor strings. This formulation is based on a set of supertwistor variables involving pure spinors and a set of constraints…
Notes on the 11D pure spinor wordline vertex operators
Max Guillen
The construction of the ghost number zero and one vertex operators for the 11D pure spinor superparticle will be revisited. In this sense, an alternative way of defining the ghost…
Supertwistor description of ambitwistor strings
Nathan Berkovits, Max Guillen, Lionel Mason
A new ambitwistor string is constructed based on a ten-dimensional supertwistor model for the massless superparticle. Although covariant quantization is complicated by reducibility…
Notes on the pure spinor superparticle
Nathan Berkovits, Eduardo Casali, Max Guillen +1
The pure spinor superparticle has been shown to describe linearized supergravity in a manifestly covariant way. A number of authors have proposed that its correlation…
Equations of motion from Cederwall's pure spinor superspace actions
Nathan Berkovits, Max Guillen
Using non-minimal pure spinor superspace, Cederwall has constructed BRST-invariant actions for super-Born-Infeld and supergravity which are quartic in the superfields…
On the equivalence of the 11D pure spinor and Brink-Schwarz-like superparticle cohomologies
Max Guillen
The pure spinor formulation of the superparticle allows a simple realization of covariant quantization, unlike the Brink-Schwarz-like superparticle. We explicitly sho…
Simplified D=11 Pure Spinor b Ghost
Nathan Berkovits, Max Guillen
A -ghost was constructed for the non-minimal pure spinor superparticle by requiring that where is the usual non-minimal pure s…
