Hidden-charm pentaquark states through the current algebra: From their productions to decays [PDF]
, 2020 There may exist seven $\bar D^{(*)} \Sigma_c^{(*)}$ hadronic molecular states. We construct their corresponding interpolating currents, and calculate their masses and decay constants using QCD sum rules.

BMS current algebra in the context of the Newman–Penrose formalism [PDF]
Classical and quantum gravity, 2019 Starting from an action principle adapted to the Newman–Penrose formalism, we provide a self-contained derivation of BMS current algebra, which includes the generalization of the Bondi mass loss formula to all BMS generators.

Celestial current algebra from Low’s subleading soft theorem [PDF]
Physical Review D, 2019 The leading soft photon theorem implies that four-dimensional scattering amplitudes are controlled by a two-dimensional (2D) $U(1)$ Kac-Moody symmetry that acts on the celestial sphere at null infinity ($\mathcal{I}$).

Three-dimensional higher-order Schrödinger algebras and Lie algebra expansions
Journal of High Energy Physics, 2020 We provide a Lie algebra expansion procedure to construct three-dimensional higher-order Schrödinger algebras which relies on a particular subalgebra of the four-dimensional relativistic conformal algebra.

OFF-CRITICAL CURRENT ALGEBRAS [PDF]
International Journal of Modern Physics A, 1995 We discuss the infinite-dimensional algebras appearing in integrable perturbations of conformally invariant theories, with special emphasis on the structure of the consequent non-Abelian infinite-dimensional algebra generalizing W∞ to the case of a non-Abelian group.

CURRENT ALGEBRAS AND QP-MANIFOLDS [PDF]
International Journal of Geometric Methods in Modern Physics, 2013 Generalized current algebras introduced by Alekseev and Strobl in two dimensions are reconstructed by a graded manifold and a graded Poisson brackets. We generalize their current algebras to higher dimensions. QP-manifolds provide the unified structures of current algebras in any dimension.

The Linear Algebra Mapping Problem. Current State of Linear Algebra Languages and Libraries [PDF]
ACM Transactions on Mathematical Software, 2019 We observe a disconnect between developers and end-users of linear algebra libraries. On the one hand, developers invest significant effort in creating sophisticated numerical kernels.

MHV gluon scattering amplitudes from celestial current algebras
Journal of High Energy Physics, 2021 We show that the Mellin transform of an n-point tree level MHV gluon scattering amplitude, also known as the celestial amplitude in pure Yang-Mills theory, satisfies a system of (n−2) linear first order partial differential equations corresponding to (n ...

Current Algebra of Super WZNW Models [PDF]
, 1993 We derive the current algebra of supersymmetric principal chiral models with a Wess-Zumino term. At the critical point one obtains two commuting super Kac-Moody algebra as expected, but in general there are intertwining fields connecting both right and ...

Simple-current algebra constructions of 2+1-dimensional topological orders [PDF]
, 2015 Self-consistent (non-)Abelian statistics in 2+1 dimensions (2+1D) are classified by modular tensor categories (MTCs). In recent works, a simplified axiomatic approach to MTCs, based on fusion coefficients Nijk and spins si, was proposed.
