    • Acceptance dependence of fluctuation measures near the QCD critical point. 

      Ling, B; Stephanov, MA (American Physical Society, 2016-03-28)
      We argue that a crucial determinant of the acceptance dependence of fluctuation measures in heavy-ion collisions is the range of correlations in the momentum space, e.g., in rapidity, ycorr. The value of ycorr ∼ 1 for ...
