A bstract We determine the light baryon spectrum on ensembles generated by the Coordinated Lattice Simulations (CLS) effort, employing N f= 2+ 1 flavours of non …
The masses of the low-lying baryons are evaluated using a total of ten ensembles of dynamical twisted mass fermion gauge configurations. The simulations are performed using …
The scalar strangeness content of the nucleon, characterized by the so-called strangeness- nucleon sigma term, is of fundamental importance in understanding its sea-quark flavor …
We perform an analysis of the QCD lattice data on the baryon octet and decuplet masses based on the relativistic chiral Lagrangian. The baryon self-energies are computed in a finite …

Inspired by the recent discovery of the Ξ cc++ by the LHCb Collaboration, we study the magnetic moments of the spin-1/2 doubly charmed baryons up to the next-to-leading order …

We study the chiral expansion of the baryon octet and decuplet masses in the isospin limit. It is illustrated that a chiral expansion of the one-loop contributions is rapidly converging up to …

We perform an analysis of Lattice QCD data on baryon octet and decuplet masses based on the chiral SU (3) Lagrangian. Low-energy constants (LEC) are adjusted to describe baryon …
We study the latest N f= 2+ 1+ 1 and N f= 2 ETMC lattice QCD simulations of the nucleon masses and extract the pion–nucleon sigma term utilizing the Feynman–Hellmann theorem …

The leading-order chiral Lagrangian for the baryon octet and decuplet states coupled to Goldstone bosons and external sources contains six low-energy constants. Five of them are …
