A Simple Algebraic Model for Few-Nucleon Systems in the Presence of Non-Abelian Superselection Rules

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2017
Traditionally, the dynamics of a quantum physical system is described on the basis of the field models, where the fundamental role is played by the algebra of quantized fields and its automorphisms (forming a compact group).

Isospin sum rules for bottom-baryon weak decays

open access: yesEuropean Physical Journal C: Particles and Fields
Isospin symmetry, as the most precise flavor symmetry, can be used to extract information about hadronic dynamics. The effective Hamiltonian operators of bottom quark weak decays are zero under a series of isospin lowering operators $$I_-^n$$ I - n ...

Dense quark matter with chiral and isospin imbalance: NJL-model consideration

open access: yesEPJ Web of Conferences, 2018
Isospin asymmetry is the well-known property of dense quark matter, which exists in the compact stars and is produced in heavy ion collisions. On the other hand, the chiral imbalance between left- and right- handed quarks is another highly anticipated ...

Strong-Isospin-Breaking Correction to the Muon Anomalous Magnetic Moment from Lattice QCD at the Physical Point. [PDF]

open access: yesPhysical Review Letters, 2017
All lattice-QCD calculations of the hadronic-vacuum-polarization contribution to the muon's anomalous magnetic moment to date have been performed with degenerate up- and down-quark masses. Here we calculate directly the strong-isospin-breaking correction

Isospin relations by counting [PDF]

open access: yesAmerican Journal of Physics, 1982
A method is given for finding the relations between reaction cross sections or decay branching fractions that result from isospin conservation. The method was discovered long ago by Shmushkevich but is not widely known. It makes no call on the usual machinery of amplitude expansions and Clebsch–Gordan coefficients, but works instead by apportioning ...

Maximum Mass Limit of Generalized MIT Compact Star: A Theoretical Study of Thin Shell Dynamics and Gravitational Lensing

open access: yesFortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract In this study, the properties, equilibrium, and stability of compact objects within the framework of teleparallel gravity with the generalized MIT bag model are investigated. By incorporating the modified field equations, the influence of the generalized bag constant on the structure and physical characteristics of quark stars and neutron ...

a0(980)–f0(980) mixing in χc1 decay [PDF]

open access: yesEPJ Web of Conferences, 2019
We investigate the isospin breaking in the χc1→π0π+π−${\chi _{c1}} \to {\pi ^0}{\pi ^ + }{\pi ^ - }$ and χc1→π0π0η${\chi _{c1}} \to {\pi ^0}{\pi ^0}\eta $ decays and its relation to the a0(980) – f0(980) mixing, which was measured by the BESIII ...

Comparative Transcriptome Reveals ART1‐Dependent Regulatory Pathways for Fe Toxicity Response in Rice Roots

open access: yesPhysiologia Plantarum, Volume 177, Issue 4, July/August 2025.
ABSTRACT Iron (Fe) is an essential element for plants, but an excess supply can have detrimental effects. Fe toxicity induces complex physiological and genetic responses, and due to this complexity, the knowledge of transcriptional regulatory mechanisms under Fe toxicity is very limited.
