The transition from quarks to hadrons in a heavy-ion collision at high energy\nis usually studied in two different contexts that involve very different\ntransverse scales: local and non-local. Models that are concerned with the\npT spectra and azimuthal anisotropy belong to the former, i.e.,\nhadronization at a local point in (\η,\φ) space, such as the\nrecombination model. The non-local problem has to do with quark-hadron phase\ntransition where collective behavior through near-neighbor interaction can\ngenerate patterns of varying sizes in the (\η,\φ) space. The two types of\nproblems are put together in this paper both as brief reviews separately and to\ndiscuss how they are related to each other. In particular, we ask how minijets\nproduced at LHC can affect the investigation of multiplicity fluctuations as\nsignals of critical behavior. It is suggested that the existing data from LHC\nhave sufficient multiplicities in small pT intervals to make feasible the\nobservation of distinctive features of clustering of soft particles, as well as\nvoids, that characterize the critical behavior at phase transition from quarks\nto hadrons, without any ambiguity posed by the clustering of jet particles.\n
