Vainshtein, and V.I. Zakharov, Nucl. Phys. B147, 385 (1979); B147, 448 (1979) Output spectral function with MEM Input OPE One hadron state m t ρ(t) 11 Borel transformation

The obtained bottomonium spectral functions contain contributions of excited states To investigate behavior of the excited states, we analyzed “residue’’ of peak (integral value of peak) We used least squares fitting to exclude contributions of continuum (one peak + continuum as Breit-Wigner + step-like function) 2012/6/22Heavy Quark Hadrons at J-PARC 2012 Υ Υ(1S), Υ(2S) and Υ(3S) 20 ・ Our method cannot separate these states
