  • We introduce novel relations between the derivatives ($\partial^{n}\rho(\lambda, m_{l})/\partial m_{l}^n$) of the Dirac eigenvalue spectrum ($\rho(\lambda, m_{l})$) with respect to the light sea quark mass ($m_{l}$) and the $(n+1)$-point correlations among the eigenvalues ($\lambda$) of the massless Dirac operator. Using these relations we present lattice QCD results for $\partial^{n}\rho(\lambda, m_{l})/\partial m_{l}^n$ ($n=1, 2, 3$) for $m_{l}$ corresponding to pion masses $m_\pi=160-55$ MeV… CONTINUE READING
