Supertwistor description of the pure spinor string
Israel Ramirez, Brenno Carlini Vallilo
We describe the pure spinor string in the using unconstrained matrices first used by Roiban and Siegel for the Green-Schwarz superstring.
Worldsheet dilatation operator for the superstring
Israel Ramirez, Brenno Carlini Vallilo
In this work we propose a systematic way to compute the logarithmic divergences of composite operators in the pure spinor description of the superstring. The comp…
Stress-tensor OPE in N=2 Superconformal Theories
Pedro Liendo, Israel Ramirez, Jihye Seo
We carry out a detailed superspace analysis of the OPE of two N=2 stress-tensor multiplets. Knowledge of the multiplets appearing in the expansion, together with the two-dimensiona…
Exact renormalization group with optimal scale and its application to cosmology
Benjamin Koch, Israel Ramirez
Assuming an effective gravitational action with scale dependent coupling constants, a consistency condition for the local form of the cut-off scale is derived. The approach is appl…
