Algebraic properties of an integrable t-J model with impurities
(1999) [Artigo de periódico]We investigate the algebraic structure of a recently proposed integrable t-J model with impurities. Three forms of the Bethe ansatz equations are presented corresponding to the three choices for the grading. We prove that ... -
Algebraic properties of the bethe ansatz for an spl(2,1)-supersymmetric t-j model
(1993) [Artigo de periódico]We investigate the algebraic structure of the supersymmetric t−J model in one dimension. We prove that the Bethe ansatz states are highest-weight vectors of an spl(2,1) superalgebra. By acting with shift operators we ... -

(2020) [Artigo de periódico]A combination of four searches for new physics involving signatures with at least one photon and large missing transverse momentum, motivated by generalized models of gauge-mediated supersymmetry(SUSY) breaking, is presented. ... -
A consistent noncommutative field theory : the Wess-Zumino model
(2000) [Artigo de periódico]We show that the noncommutative Wess–Zumino model is renormalizable to all orders of perturbation theory. The noncommutative scalar potential by itself is non-renormalizable but the Yukawa terms demanded by supersymmetry ... -
Coupling of fermions to the three-dimensional noncommutative CP/sup N-1/ model : minimal and supersymmetric extensions

Lorentz symmetry breaking in the noncommutative Wess-Zumino model : one loop corrections
(2006) [Artigo de periódico]In this paper we deal with the issue of Lorentz symmetry breaking in quantum field theories formulated in a noncommutative space-time. We show that, unlike in some recent analysis of quantum gravity effects, supersymmetry ... -
On the finiteness of noncommutative supersymmetric QED/sub 3/ in the covariant superfield formulation
(2003) [Artigo de periódico]The three-dimensional noncommutative supersymmetric QED is investigated within the superfield approach. We prove the absence of UV/IR mixing in the theory at any loop order and demonstrate its one-loop finiteness. -
