Time resolution of TileCal and searches for heavy metastable particles
Pagáčová, Martina ; Leitner, Rupert (advisor) ; Němeček, Stanislav (referee)
Title: Time resolution of TileCal and searches for heavy metastable parti- cles Author: Martina Pagáčová Department: Institute of Particle and Nuclear Physics Supervisor: Doc. RNDr. Rupert Leitner, DrSc. Supervisor's e-mail address: Rupert.Leitner@cern.ch Abstract: In the present work, the timing of the ATLAS TileCal is stud- ied using the single hadron collision data. The time resolution and also the mean time response depend on the energy deposited in a given cell. The results are compared to the previous analysis with jets and muons. Precise time-of-flight measurement using TileCal can be used to identify the heavy long-lived particles predicted by the models of physics beyond the standard model. Their mass can be reconstructed by combining with the momentum measurement in the ATLAS inner detector. Finally, the mass resolution of an exotic particle with mass M = 600 GeV is estimated. Keywords: ATLAS experiment, TileCal, time resolution, stable massive particles

Response of the ATLAS Tile Calorimeter
Adámek, Tomáš ; Davídek, Tomáš (advisor) ; Faltová, Jana (referee)
TileCal is the Hadronic calorimeter covering the most central region of the ATLAS experiment which is one of the four major experiments at the Large Hadron Collider (LHC) at CERN. Main area of interest of this bachelor thesis is to examine the energy response and resolution of tested modules to electrons. Furthermore, the goal of this work is to make correction to the energy response with respect to the periodic structure of TileCal's cell.

Odezva kalorimetru Tilecal na miony

Title: Tile Calorimeter response to muons Author: Tomas Javurek Department: Institute of Particle and Nuclear Physics Supervisor: RNDr. Tomas Davidek, Ph.D. Supervisors e-mail address: davidek@ipnp.troja.mff.cuni.cz Abstract: The aim of present work is investigation of Tile calorimeter (subde- tector of ATLAS experiment) response to muons. Muons can help to monitor spatial non-linearities in this hadronic detector. Graphs of unifromities are used for these purposes i.e. dependence of dE/dx (deposited energy per unit length) on azimuthal angle φ and polar angle θ which is represented by pseu- dorapidity η. Finally the dependence of dE/dx on energy was also studied. Keywords: TileCal, muon, uniformity, energy loss
