By developing a description of the dependence of this binding energy on the up, down and strange quark masses that allows a controlled chiral extrapolation, we explore the hypothesis that this state is to be identified with the H dibaryon. Taking as input the recent results of the HAL and NPLQCD Collaborations, we show that the H dibaryon is likely to be unbound by 13 _ 14 MeV at the physical point.en©2011 American Physical SocietyJournal article002011238710.1103/PhysRevLett.107.0920040002942684000032-s2.0-8005199953827940Thomas, A.
