The Sharp Lepton Quandary: Reasonable Cautions

  • James J. Griffin


Surprisingly, the new APEX experiment designed[1] to measure a definitive invariant mass distribution1 of the sharp pairs previously observed[2, 3] in similar heavy ion studies reports null results[4, 5]. Although it asserts no direct conflict with any data reported by EPOS/I, and critics claim that its published analysis is inconsistent [6, 7] and not contradictory to EPOS/I, the APEX report nevertheless seems to have encouraged the view that the earlier (EPOS/I) observations were erroneous, and by extrapolation, that the whole (e + e ) Puzzle data set can be dismissed as an unfortunate set of physically meaningless statisical fluctuations.
