Abstract

Notes

  1. 1.

    The resolution is determined by the width of the slope of the turn-on curve. A sharper turn-on curve indicates better offline resolution.

  2. 2.

    On a turn-on curve, one identifies the plateau by the x-value such that the efficiency is approximately 99%. A trigger with a lower plateau is more preferred as it reduces the selections needed to be applied on the offline object.

  3. 3.

    The gTowers selected correspond to an η range of the original proposal of gFEX. These studies will need to be updated again using current Monte Carlo simulation upgrade samples and an updated η range.

  4. 4.

    These studies need to be redone with equal rate settings.
