Workshop, Chengdu, China ShinIchi Esumi, Univ. of Tsukuba8 Bulk expansion initialfinal Path length (angle w.r.t.  n ) dependence of energy-loss would be a dominant source of high p T or reconstructed jet v n. Depending on the shape (amount and direction: blue part), the lost energy re-distribution should then influence the low to mid p T v n and possibly also affect the bulk expansion in the later stage.
