Why Isospin Is Not Dynamically Broken
نویسنده
چکیده
Isospin invariance, P and CP could well have been dynamically broken along with chiral invariance by the quark-antiquark condensate (<{q>. #0) . We show, however, that under appropriate circumstances, the conservation of isospin, P and CP is "natural". (Submitted to Phys. Rev. Lett.) * This work was supported by the Department of Energy under contract number DE-AC03-76-SF00515.

An isospin analysis of B → ππ decays yields sin 2α, where α is the usual CKM angle α ≡ arg[−V td V * tb /(V ud V * ub)] without hadronic uncertainty if isospin is a perfect symmetry. Yet isospin symmetry is broken not only by electroweak effects but also by the u and d quark mass difference — the latter drives π 0 − η, η ′ mixing and converts the isospin-perfect triangle relation between the B ...

An isospin analysis of B → ππ decays yields sin 2α, where α ≡ arg[−VtdV ∗ tb/(VudV ∗ ub)] and Vij is a CKM matrix element, without hadronic uncertainty if isospin is a perfect symmetry. Isospin, however, is broken not only by electroweak effects but also by the u and d quark mass difference. The latter drives π − η, η mixing and converts the isospin-perfect triangle relation between the B → ππ ...
متن کاملIsospin symmetry breaking and the nuclear shell model
The effect of isospin symmetry breaking on level statistics has been examined with the nuclear shell model. The eigenvalues and electromagnetic transitions were calculated with the program OXBASH for the nuclide 26Al for conserved isospin and for broken isospin. The long-range correlations of the eigenvalues, as measured by ∆3, show good agreement between the experimental results and the calcul...
متن کاملStudies of the QCD and QED effects on Isospin breaking
The isopin breaking effect due to different masses and electric charges between up/down quarks are stuided non-perturbatively using lattice QCD+QED. Up, down, and strange quark masses are determined using K±,K0, and π± meson masses as inputs. The charge splitting of Kaon mass, mK± −mK0 , is broken up into the part coming from up, down quark mass difference and that from electromagnetic effects....
