The QCD phase diagram for nonzero isospin-asymmetry [PDF]
, 2017 The QCD phase diagram is studied in the presence of an isospin asymmetry using continuum extrapolated staggered quarks with physical masses. In particular, we investigate the phase boundary between the normal and the pion condensation phases and the ...

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

Two Micron‐Size Dark Dimensions
Fortschritte der Physik, Volume 73, Issue 8, August 2025.Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

A Simple Algebraic Model for Few-Nucleon Systems in the Presence of Non-Abelian Superselection Rules
Учёные 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
European Physical Journal C: Particles and FieldsIsospin 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
EPJ 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 ...

Isospin relations by counting [PDF]
American 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 ...

Fortschritte 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 ...
