We present preliminary results from the first attempt to reconstruct the spectral function in the nucleon and A channels from lattice QCD data using the maximum entropy method (MEM). An advantage of the MEM analysis is to enable us to access information of the excited state spectrum. Performing simu
The chiral extrapolation of the nucleon mass, M n , is investigated using data coming from 2-flavour partially-quenched lattice simulations. A large sample of lattice results from the CP-PACS Collaboration is analysed using the leading one-loop corrections, with explicit corrections for finite latti
