Performance of the Atlas Forward Calorimeter and search for the invisible Higgs via vector boson fusion at ATLAS

Calibration of the ATLAS forward calorimeter and a study of the top quark production cross-section measurement in the dilepton channel

“…In the test beam setup the pulse shape was sampled seven times every 25 ns (7 , taken from SPICE simulations [21] of the FCal electronics readout [22] (and later verified using test beam data [23]).…”

“…The channels chosen were those with significant energy deposition over the electronic noise (A > 5 x a), to ensure the resulting pulse shape was that of a physics pulse shape, and not noise. More details of this procedure are found in [23].…”

A study of hadronic calibration schemes for pion test beam data in the ATLAS forward calorimeter

“…With the basic structure of the modular weighting scheme in mind, the next step in complexity for a weighting scheme can be explored. In what will be referred to as the radial weighting scheme, motivated by previous analyses [21], the energy deposits in the various FCal readout channels are assigned to radial bins based on the particular readout channel's radial 1 distance from the impact position, as illustrated by To determine the bin to which a particular readout channel or cell is assigned, the projected (x, y) position of the beam particle on the surface of each FCal module for a given event is first determined and set to be the centre of the concentric radial bins.…”
