"Baryon interactions from Lattice QCD by Luscher's finite volume method and HAL QCD method"

Presented by Takumi Iritani, Stony Brook University

Thursday, December 17, 2015, 12:30 pm — Building 510 Room 2-160

Both Luscher's finite volume method and HAL QCD method are used to analyze the hadron-hadron interaction in lattice QCD. However, some systematic discrepancies are reported between them.For example, Luscher's method shows the bound states of both deuteron and di-neutron at the heavy pion mass,while these channels are scattering states from HAL QCD method. In this talk, to understand the deviations between them, we investigate the baryon interaction from both methods with the same lattice setups.From a systematic comparison of two methods, we clarify the problems in the previous studies. We also discuss the improvement of the analyses.
