ON RENORMALIZATION OF POISSON–LIE T-PLURAL SIGMA MODELS

Acta Polytechnica, 2013
Covariance of the one-loop renormalization group equations with respect to Poisson–Lie T-plurality of sigma models is discussed. The role of ambiguities in renormalization group equations of Poisson–Lie sigma models with truncated matrices of parameters ...

Vacua, walls and junctions in GNF,NC

Nuclear Physics B, 2019
We discuss vacua, walls and three-pronged junctions of the mass-deformed nonlinear sigma models on the Grassmann manifold GNF,NC=SU(NF)SU(NC)×SU(NF−NC)×U(1), which are non-Abelian gauge theories for NC≥2. Polyhedra are proposed in [1] to describe Bogomol'

A Note on Wess-Zumino Terms and Discrete Symmetries

, 1998
Sigma models in which the integer coefficient of the Wess-Zumino term vanishes are easy to construct. This is the case if all flavor symmetries are vectorlike. We show that there is a subset of SU(N)XSU(N) vectorlike sigma models in which the Wess-Zumino

European Physical Journal C: Particles and Fields
The transverse momentum spectra and integrated yields of anti- $$\Sigma $$ Σ hyperons ( $$\overline{\Sigma }^{\pm } $$ Σ ¯ ± ) have been measured in $$\text {pp}$$ pp and $$\text {p}{-}\text {Pb}$$ p - Pb collisions at $$\sqrt{s_{\textrm{NN}}}=5.02$$ s ...

Yang–Baxter sigma models based on the CYBE

Nuclear Physics B, 2015
It is known that Yang–Baxter sigma models provide a systematic way to study integrable deformations of both principal chiral models and symmetric coset sigma models.

Supersymmetric Poisson and Poisson-supersymmetric sigma models

Journal of High Energy Physics
We revisit and construct new examples of supersymmetric 2D topological sigma models whose target space is a Poisson supermanifold. Inspired by the AKSZ construction of topological field theories, we follow a graded-geometric approach and identify two ...

Twisting gauged non-linear sigma-models

, 2008
We consider gauged sigma-models from a Riemann surface into a Kaehler and hamiltonian G-manifold X. The supersymmetric N=2 theory can always be twisted to produce a gauged A-model.

Soft theorems for two-scalar sigma models

Journal of High Energy Physics
In this paper, we study the scattering amplitudes and soft theorems for the sigma models with two scalars. We show that if the particles are Goldstone bosons, then you necessarily get Adler zero with no possibility for non-trivial soft theorems.

Infrared properties of two-dimensional SU(N)/H nonlinear $\sigma$ models at nonzero $\theta$ angles

SciPost Physics
A general strategy is proposed to explore the low-energy properties of two-dimensional nonlinear $\sigma$ models with $\theta$ terms. We demonstrate its application to nonlinear $\sigma$ models with the target space $SU(N)/H$, which include $\mathbb{C}P^{
