Scattering and duality in the 2 dimensional OSP(2|2) Gross Neveu and sigma models [PDF]
, 2010 We write the thermodynamic Bethe ansatz for the massive OSp(2|2) Gross Neveu and sigma models. We find evidence that the GN S matrix proposed by Bassi and Leclair [12] is the correct one.

On the B-twisted topological sigma model and Calabi-Yau geometry [PDF]
, 2014 We provide a rigorous perturbative quantization of the B-twisted topological sigma model via a first order quantum field theory on derived mapping space in the formal neighborhood of constant maps.

Sigma models with negative curvature
Physics Letters B, 2016 We construct Higgs Effective Field Theory (HEFT) based on the scalar manifold H^n, which is a hyperbolic space of constant negative curvature. The Lagrangian has a non-compact O(n,1) global symmetry group, but it gives a unitary theory as long as only a compact subgroup of the global symmetry is gauged.

"Six SIGMA" standard as a level of quality of biochemical laboratories
Sanamed, 2022 The principal role of biochemical laboratories is responsibility for reliable, reproducible, accurate, timely, and accurately interpreted analysis results that help in making clinical decisions, while ensuring the desired clinical outcomes.

Gravitating $\sigma$ Model Solitons
, 1998 We study axially symmetric static solitons of O(3) nonlinear $\sigma$ model coupled to (2+1)-dimensional anti-de Sitter gravity. The obtained solutions are not self-dual under static metric. The usual regular topological lump solution cannot form a black

Gauged (2,2) Sigma Models and Generalized Kahler Geometry [PDF]
, 2006 We gauge the (2,2) supersymmetric non-linear sigma model whose target space has bihermitian structure (g, B, J_{\pm}) with noncommuting complex structures.

Renormalizability of the gradient flow in the 2D O(N) non-linear sigma model [PDF]
, 2014 It is known that the gauge field and its composite operators evolved by the Yang--Mills gradient flow are ultraviolet (UV) finite without any multiplicative wave function renormalization.
