No parity anomaly in massless QED3: a BPHZL approach
Oswaldo M. Del Cima, Daniel H. T. Franco, Olivier Piguet +1
In this letter we call into question the perturbatively parity breakdown at 1-loop for the massless QED_3 frequently claimed in the literature. As long as perturbative quantum fiel…
A Vector Supersymmetry Killing the Infrared Singularity of Gauge Theories in Noncommutative Space
Daniel N. Blaschke, François Gieres, Olivier Piguet +1
We show that the "topological BF-type" term introduced by Slavnov in order to cure the infrared divergences of gauge theories in noncommutative space can be characterized as the co…
A Vector Supersymmetry in Noncommutative U(1) Gauge Theory with the Slavnov Term
Daniel N. Blaschke, Francois Gieres, Olivier Piguet +1
We consider noncommutative U(1) gauge theory with the additional term, involving a scalar field lambda, introduced by Slavnov in order to cure the infrared problem. we show that th…
Nonrelativistic Supersymmetry in Noncommutative Space
Gustavo S. Lozano, Olivier Piguet, Fidel A. Schaposnik +1
We analize a model of non relativistic matter in 2+1 dimensional noncommutative space. The matter fields interact with gauge fields whose dynamics is dictated by a Chern Simons ter…
Observables in Topological Yang-Mills Theories With Extended Shift Supersymmetry
Clisthenis P. Constantinidis, Olivier Piguet, Wesley Spalenza
We present a complete classification, at the classical level, of the observables of topological Yang-Mills theories with an extended shift supersymmetry of N generators, in any spa…
Superspace Gauge Fixing of Topological Yang-Mills Theories
Clisthenis P. Constantinidis, Olivier Piguet, Wesley Spalenza
We revisit the construction of topological Yang-Mills theories of the Witten type with arbitrary space-time dimension and number of ``shift supersymmetry'' generators, using a supe…
