On the Weyl anomaly for chiral fermions
Enrique Alvarez, Luis Alvarez-Gaume, Jesus Anero +1
We compute the parity-odd part of the Weyl anomaly for chiral fermions in a background gravitational field. We start from a manifestly real form of the Lagrangian (that is, not onl…
Quantum noncommutative ABJM field theory: four- and six-point functions
Carmelo P. Martin, Josip Trampetic, Jiangyang You
Following our previous paper Quantum noncommutative ABJM theory: first steps, JHEP {\bf 1804} (2018) 070), in this article we investigate one-loop 1PI four-, and six-point function…
Entanglement through high-energy scattering in noncommutative quantum electrodynamics
Carmelo P. Martin
We analyze the tree-level generation of entanglement through some key scattering processes in massless quantum electrodynamics on canonical noncomutative spacetime with space-space…
One loop analysis of the cubic action for gravity
Enrique Alvarez, Jesus Anero, Carmelo P. Martin
We analyze some aspects of the cubic action for gravity recently proposed by Cheung and Remmen, which is a particular instance of a first order (Palatini) action. In this approach…
Tree-level four-point function for a scalar field conformally coupled to Einstein's gravity on Euclidean AdS4
Carmelo P. Martin
Using the AdS/CFT correspondence, we compute the tree-level four-point boundary scalar correlation function for a scalar field conformally coupled to the graviton field on Euclidea…
