On the importance of NNLO QCD and isospin-breaking corrections in $$\varepsilon '/\varepsilon $$ [PDF]
The European Physical Journal C, 2019 Following the 1999 analysis of Gambino, Haisch and one of us, we stress that all the recent NLO analyses of $$\varepsilon '/\varepsilon $$ε′/ε in the Standard Model (SM) suffer from the renormalization scheme dependence present in the electroweak penguin

Electromagnetic and strong isospin-breaking corrections to the muon g−2 from lattice QCD+QED [PDF]
Physical Review D, 2019 We present a lattice calculation of the leading-order electromagnetic and strong isospin-breaking corrections to the hadronic vacuum polarization (HVP) contribution to the anomalous magnetic moment of the muon.

Isospin breaking decays as a diagnosis of the hadronic molecular structure of the Pc(4457) [PDF]
Physical Review D, 2019 The LHCb Collaboration announced the observation of three narrow structures consistent with hidden-charm pentaquark states. They are candidates of hadronic molecules formed of a pair of a charmed baryon and an anticharmed meson.

Probing Mechanical and Chemical Instabilities in Neutron-Rich Matter [PDF]
, 2001 The isospin-dependence of mechanical and chemical instabilities is investigated within a thermal and nuclear transport model using a Skyrme-type phenomenological equation of state for neutron-rich matter.

Isospin Conservation in Neutron Rich Systems of Heavy Nuclei
EPJ Web of Conferences, 2018 It is generally believed that isospin would diminish in its importance as we go towards heavy mass region due to isospin mixing caused by the growing Coulomb forces.

Two- and Three-Pion Finite-Volume Spectra at Maximal Isospin from Lattice QCD. [PDF]
Physical Review Letters, 2019 We present the three-pion spectrum with maximal isospin in a finite volume determined from lattice QCD, including excited states in addition to the ground states across various irreducible representations at zero and nonzero total momentum.

Investigation of Low-Density Symmetry Energy via Nucleon and Fragment Observables
, 2007 With stochastic transport simulations we study in detail central and peripheral collisions at Fermi energies and suggest new observables, sensitive to the symmetry energy below normal density.

Isospin dependence of the three-nucleon force [PDF]
, 2004 We classify $A$--nucleon forces according to their isospin dependence and discuss the most general isospin structure of the three--nucleon force. We derive the leading and subleading isospin--breaking corrections to the three--nucleon force using the ...

The pn interaction and isospin symmetry
Frontiers in PhysicsA possible correlation between isospin symmetry/breaking and the average proton-neutron interaction of the last particles, δVpn, is discussed. This correlation is tested for Tz = ±1/2 mirror nuclei in terms of a differential of δVpn, Δ(δVpn), and their ...
