Isospin odd πK scattering length
We make use of the chiral two–loop representation of the πK scattering amplitude [J. Bijnens, P. Dhonte and P. Talavera, JHEP 0405 (2004) 036] to investigate the isospin odd scattering length at next-to-next-to-leading order in the SU(3) expansion. This scattering length is protected against contributions of m s in the chiral expansion, in the sense that the corrections to the current algebra r...

متن کاملIsospin symmetry breaking in mirror nuclei
Isospin symmetry is one of the fundamental symmetries we can identify in nuclei. This is related to the approximate charge symmetry and charge independence of the strong interaction. On this hypothesis, the level schemes of mirror nuclei (with exchanged number of protons and neutrons) should be identical. Of course some differences appear due to the fact that the Coulomb interaction breaks isos...
متن کاملOdd Independent Transversals are Odd
We put the final piece into a puzzle first introduced by Bollobás, Erdős and Szemerédi in 1975. For arbitrary positive integers n and r we determine the largest integer ∆ = ∆(r, n), for which any r-partite graph with partite sets of size n and of maximum degree less than ∆ has an independent transversal. This value was known for all even r. Here we determine the value for odd r and find that ∆(...
