Direct lattice calculation of m_d - m_u

Direct lattice calculation of m_d - m_u [electronic resource]

We describe an independent method for determining the strong-isospin breaking mass parameter, 2d = md - mu, which utilizes the baryon spectrum. We use a prudent partially quenched choice of splitting the valence quark masses symmetrically about the light sea quark mass. This choice has the consequen...
